Conrad-Johnson Premier 350 discussion

[Puma Cat]

This thread is for discussion of the famous Conrad-Johnson Premier 350 amplifier:

From the C-J website:
Hybrid Solid-State Circuit.
The Premier 350 benefits from an interesting hybrid of solid-state technologies. The distortion characteristics of an amplifier are dominated by it's voltage gain stage. We have selected FETs for this application, because, like tubes, and unlike bi-polar transistors, they produce almost no strident odd-order harmonic distortion. The output stage of an amplifier must efficiently couple the high amplitude signal produced by the voltage gain stage to the loudspeaker system to assure the power and control needed to produce a musically accurate response. Bi-polar devices have been specified for the output stages of these amplifiers because they offer about 1/4th the output impedance of a MOSFET, resulting in much better control of the loudspeaker. This is most noticeable in faster, more solid bass response.

Zero Feedback.
Negative feedback is an engineering technique used to reduce measured distortion. While feedback does achieve this goal, it also introduces aberrations in the tran-sient response characteristics of the circuit. The Premier 350 uses conrad-johnson's unique auto-linear gain block for the voltage gain stage, which achieves low distortion with zero loop feedback by exploiting the symmetrical distortion properties of n and p channel fets.

Solid Power Supplies.

Power supply circuits present a parallel signal path to the audio circuits. Ideally this signal path provides ac signals with a zero impedance path to ground. Any deviation from this ideal is reflected in the reproduced audio signal. Thus the power supplies are as important to audio performance as the audio circuits and must be accorded equal attention in design. The Premier 350 features a discrete dc regulators to power the critical voltage gain stage.

Quality Parts.

As with all Premier components, the Premier 350 is constructed from the highest quality, carefully selected parts for unrivaled sonic performance and reliability. The circuits employ polypropylene and polystyrene capacitors extensively, except in the main power supply storage, where special high-speed electrolytics are used because of the extremely high capacitance required. The audio circuit and related power supplies utilize precision low inductance laser-trimmed metal foil resistors. The obsession for parts quality extends to the high quality, gold plated input jacks and output connectors - even the internal wiring is chosen on the basis of its sound quality in its specific application.

Thoughtful engineering, specification of the finest available component parts, and painstaking care taken in production make this an audio amplifier without peer in music reproduction. We invite you to arrange an audition with your conrad-johnson dealer to confirm for yourself the extraordinary musical performance of the Premier 350.

Dealer's bro in law had one in storage never opened. Nixed home theater room. I did major outreach at right time. Talked to CJ and confirmed unit was new and authorized. Seller even double boxed and did 2 day fed ex. I am so grateful. I feel very fortunate.

Here is system it is going into.

Maggie 3.7s are stable at 4 ohm so PR 350 should effortlessly handle them.

Another shout out to ToneAudio and AA which really incented me to join the CJ family. Same music-first, holistic, equipment with loyal fan base as I read in Shindo forums.

[Coppy]

We need Coppy to chime in...he's got a Pr350 IIRC....

I'm here... just tuned in to this thread. You folks know how I feel about this AMP, it's an incredible bargain for this level of performance... can't let it go. Some say it's a bit delicate but I've not had any issues although I'm careful not to connect/disconnect anything while it's on or has been on. Those big caps inside retain a good deal of their power long after it's shut down. As has been said, be careful not to short the outputs... ever. I think some folks at dealers who are constantly pulling equipment in and out for demo have had difficulty when they were too casual about connections.

Now that's said, enjoy the dynamics... the P350 will drive just about anything. And it's response is dead flat. It's still a reference amp for reviewers overseas. It's difficult for them to use our beloved tube amps as the don't always match speakers. Here's a ToneAudio review if it comes through on this post...

Hmm... maybe not. Got to figure out how to add this PDF file. In the meantime, enjoy the music.

Stephen... how are the KT120s doing?

:music:

[Puma Cat]

Coppy,
The KT-120s are doing great, and the interesting thing is they seemed to have created a wonderful synergy with the CT-5. I spent the evening listening to the CT-5 last night with my Rega P5 and I'm going to have to rethink things. The fuller, weightier, and punchier presentation of the KT-120s has filled in some of the gaps I've always felt the CT-5 had compared to the Premier 17. Namely, while the CT-5 was quieter, faster, more detailed and transparent, it was thinner, leaner, flatter, more neutal and smaller in presentation than the Premier 17.

The KT-120s seems to have really brought the CT-5 to another level in terms of these gaps. Gotta say, the CT-5 sounded REALLY good last night. The other remarkable thing is how good the Rega P5 is compared to my much more expensive Michell/SME V/Koetsu UV.

Interesting thing to think about, about how a power tube in an amp can create greater synergistic results with a preamp.

It never ceases to amaze me how simply getting properly matched equipment together makes such a huge difference in the sound. Some of the world's best equipment can be so disappointing paired badly together. And, it's not at all obvious why that is or how to match things except trial and error. Why do Transparent cables work well with Wilson speakers? Certain interconnects work better in certain systems? There are a few obvious electrical issues like impedance and damping factor but look at what a tube change in your amp did for the amp/preamp combo. The output of the CT-5 was probably always there but only now can your amp fully express it. Maybe we need a thread on just this subject. Glad to hear everything is working so well for you.

Bob

[Puma Cat]

Bob,
Yes, I think we need a new thread on just this subject! ;)

I'm listening to the CT-5 right now again, and it sounds fab; it's strikingly quiet for a tube preamp.

[dpod4]

Just plugged my CJ350 in, after listening to my reference CDs thru my VAC 300.1a amp. Wow, I guess that's what bass and punch is supposed to sound like thru my Magnepan 3.7s! I kid you not, I muted and unmuted my Velodyne DD15+ and could no longer hear the subwoofer...my Magnepans are now taking over the low end via the Premier 350. I was bracing myself for loss of delicacy at the top, but right of the box, first 1/2 hour turned on the CJ is much better in the mids and highs than I was expecting -- not overly bright nor rolled off. Nice to know the spatial soundstaging inherent in my VAC preamp carries over to the SS amp. Other thing I am noticing is incredible combination of macro and micro dynamics.

[chessman]

Sounds like you have a winner. Congrats!!

[joeinid]

Lets get a CJ Premier 350 re-issue group buy going !!! I'm in!

When I called CJ a few weeks ago they said it would be $15-16k + to build that amp today. From initial listening I am not surprised. Not quite as liquid smooth as my VAC (not broken in tho) but sheer force and presence is mind boggling.

Gee guys

I almost wish I did not sell my prem350 a few years back.

that said, my prem 8a's are the better sounding amplifiers, especially with 3d floating image, tone and upper frequency extension and "air"

still, would have been nice to use during summer :-)

Agree it is tough to beat tubes for nonfatiguing natural fluid holographic mids and highs. I can't imagine selling my VAC 300.1a

[Coppy]

Gentlemen, start your engines...

dpod my friend... I should add two more suggestions:

First... as you doubt already know, that thing is a heavy 85 lb. and is not a well balanced lift. The left side is so much heavier than the right. It's a hoss to move around... and please be careful. The cooling fins on the left side all have sharp edges and will show no mercy to your forearms.

Secondly... although this may be a good thing as you already like the sound...this was one of the first units in which C-J used proprietary teflon caps. I don't remember a break-in issue but the sound should only get better for you with time. I've never found the sound at all fatiguing and none of the reviewers that I've read did either. Is it as holographic as my LP140 tubes, probably not but it sure is faster with tighter lows. Back to the Ravens.

Enjoy the champaign beast! :yes:

If it will come through, here is an excerpt from Roy Gregory's review in HiFi Plus of the P350 referring to the teflon caps: /Users/rbc7/Desktop/Screen Shot 2011-11-24 at 10.50.27 PM.png. Got to figure out how to add this stuff here, but maybe you can look it up on their site. There were reviews in both HiFi+ and ToneAudio. I might also have the original C-J product flier someplace. If so I can e-mail a picture to you.

I can remember discussing the caps with Tor Sivertsen (then sales manager for C-J) when I bought the 350 some years ago.

Thanks, Bob. I had read where most of the weight was on the left side so I was super careful lifting and placing it. Thanks for the good counsel. CJ and others have also advised about the burn in for Teflon caps - 300+ hours to hit their stride so I will be certain to listen for changes although I think it sounds awesome out of the box. Your description is very accurate. The sound is very fast. I feel like all veils have been lifted without any glare or edginess being present (I'm very sensitive to overly strident or etching sonics). Cheers.

dodp4,
How is the Premier 350 settling in?

[dpod4]

dodp4,
How is the Premier 350 settling in?

Thanks for asking. I now know why this component has a cult following and why Jeff Dorgay encouraged me to be patient and find one. It is amazing. Just noticed tonight listening to a Naim cd recording on my modwright 5400es that the Pr350 is sounding even better - more richness and meat on the bones. I sent an email today to CJ stating how happy I am (a portion pasted below). While my (broken-in) VAC 300.1a amp has a hard to equal, impossible to beat holographic harmonic magic to it, the CJ is pleasing in similar and different ways and better in others like micro/macro dynamics etc. I could not be happier (unless the loud startup pop wasn't part of the circuitry). The fact I landed a NOS in-perfect-condition unit makes me even more grateful. Sorry to gush but this 350 is perfect for my Magnepan 3.7s and my ears. I'm now a CJ fan for life. Thx to die-hard CJ loyalists on AA as that incented my search.

In part, sent to CJ earlier today and was told it was being forwarded to mssrs Conrad and Johnson:

"....I hooked up the Premier 350 into my high-end 2 channel audio system and let it compete against my tube amplifier. It held its own in a big way and that was right out of the box! The sweet, delicate nature of this amplifier is matched by its deliberate grip and dynamic finesse. It is a perfect solid state amplifier, delivering the power and speed of solid state, and the spatial imaging, delicate mids/highs and non-fatiguing sound of tubes. My favorite piece of equipment has been my Benz Micro LP-S moving coil cartridge. I think it was just displaced by the Premier 350. Amazing, amazing, amazing. Hard to believe after it breaks in it will sound even better...."

You've got quite a system there; it's impressive. How do you like the Soundsmith Ebony Voice? I've always liked the Ebony Voice when I've heard it in Peter's rooms at audio shows; I prefer it to the Strain Gauge, the Susurro and the new "cactus needle" cartridge.

Thanks, Stephen,
The Voice Ebony is very fast, detailed, open and airy. Throws a massive soundstage...biggest I've heard . I'm not sure I have the VTA dialed in and I'm not sure how much of what I am hearing is the triplanar and/or the modified empire table. I need to spend more time with it and compare to Innovation and Graham/Benz. I am thinking I wish I had stuck with just one table (ESP now since it has two arms). I grew up with an Empire 698 so the Atmasphere was an impulse purchase. Will likely sell it if anyone is interested here....a turnkey system with a new triplanar arm (mfgd in this past summer). I had a local audiophile friend over who's ears I trust a lot and encouraged me to keep it. Darrin

[dpod4]

Update. Pr350 is becoming more awesome each day. Listened to sacd Rickie Lee Jones last night (Pirates, Woody and Dutch track). Best I have ever heard it bar none. Nothing between me and RLJ vocals. Heard details never noticed before. The CJ350 remained sweet but lifted all veils.

This is the album/track I remember listening to as a teenager with my maggies and modified hafler amp and empire ttable/grado setup. All the Maggie traits I remember and love but more detail sweetness dynamics and MUSIC. Front to back imaging depth is amazing. What amazes me is amount of detail and extension coupled with perfect sweetness. Not as holographic as VAC tubes tho....

It's a lot like a Burmester 911MkIII except perhaps just a skosh warmer and "rounder", but not by much. If you can imagine a 911 MkIII done by C-J you'd have the Premier 350.

The word that comes to mind is "giddy" to describe how I am feeling about the pr350. A few hundred hours and it sounds 40-50% better from its original awesomeness. Fuller, richer, more musical, more textured harmonics, tighter slam. It is a perfect amp, especially driving my stable 4 ohm Magnepan 3.7 speakers. Darrin

[Rayooo]

Dont' get me wrong, I love the JC-1s, just wish I could've had a listen with PR350 and my 3.7s prior.

It feels like winning the lottery for sure. Same way I feel about my 2004 VW R32. Soooo fortunate to have purchased one. If anyone is in Portland OR area feel free to drop me a line and I will have you over to listen to my setup. The CJ 350 has me in a state where I am not thinking about "what to upgrade next?" I know one day I will likely add a second VAC 300.1a tube amp, but I'm super super super happy right now. Am grateful to all the CJ loyalists on AA as it tipped me over the top on my hunt for the CJ PR350. First counsel came from Jeff Dorgay offline for which I'm grateful. Darrin

[dpod4]

By the way, my FAVORITE quality of the CJ Pr350 is what I love about Maggies...

The 350 strips ALL VEILS between me and music...total transparency and presence...but with absolutely NO GLARE, ETCH, SHRILLNESS, SIBILANCE or FORWARDNESS WHATSOEVER. It is like a magic trick...all punch and clarity of best solid state plus all the richness and sweetness of tubes. An amazing hat trick. Sorry to gush again, but man, this amp kicks it.

[dpod4]

Dont' get me wrong, I love the JC-1s, just wish I could've had a listen with PR350 and my 3.7s prior.

Those JC-1s are legend...wait for it...ary. The dealer who sold me my VAC amp recommended the JC-1s as his go-to reference on the solid state side.

You guys are driving me crazy with you universal drooling over the prem350:D

There is one locally available in Aust but the guy is asking too much.

How much do used one's go for now?

Anyway, can't go into debt as I have a significant change in the system about to happen.

I think used ones go for 4-5k. Thing to remember tho is this amp today new if CJ built them would cost $15-17k. It easily competes with my $19.5k VAC amp.

Listening to Rickie Lee Jones tonight I realize a few hundred hours burn in for the Pr 350 is equivalent to putting butter on toast.

The price is pretty high, new retail was $7500, median price in the Audiogon Blue Book is $4790.

I looked it up also and he has $15K new retail. Way off. He should be sending me a picture. I'll see how low he will go. :thumbsup:

Yes, it is high. The 15k was probably the Aussie retail back when our $ was .56 to the US. It is basically a lie, as all audiogon pricing should be in US retail, and that was never 15k.

I was tempted but too much for me at this time. But its all supply and demand right.

Please note that this is being sold by a dealer in Perth and the prem350 is on consignment fronm one of their customers.

Personally I would wait for one in the US to come up. Freight will be EXPENSIVE to the USA.

You can say that again.

Not only that, but you then have to pay to ship to C-J and back after the conversion once you do get it in the U.S. That will be a minimum of another $200.

If the price was right, I'd just have him ship straight to CJ with a proper RMA.

[microstrip]

Is it a big deal to convert a Premier 350 from 230V to 120V by Conrad Johnson?

Not a big deal, but you have to know how to do it. I did the opposite a few years ago. You have two transformers to re-wire - as far as I remember there is a smaller one behind the faceplate that powers the switch-on relays and control system. It was not easy to find!

But I stand by the design...so if you own something of mine, and want...I'll really unleash it, with parts we couldn't possibly spec and still sell it for what we originally did".

Am I reading too much into that? lol...that's the way I take it. I tell ya...for what they cost you on the used market, I'd take an RLD-1 and DNA-225, and let SMc spruce them up for me in a heartbeat.

Do some simple research. Jeff Behr is a well respected member of audio asylum and has a long history of owning cj gear. He certainly would not mention Ed's name at cj if it was not legit.

I absolutely meant no offense. I don't know Jeff Behr, or Asylum at all...so I was just speaking in general. "Divorce" and "widow"-sales are common scams, on Craigslist and such. You've seen the ads: "don't know what this is...it was my late/ex husband's; it's really heavy and says Krell on it"...lol.

Plus...I've been trading used gear for quite some time...close to 10 years or so; granted, probably not as long as some of you...but I've NEVER seen a deposit ahead of local pick-up. But I'm obviously glad it worked out for Joe...and jealous...and again, didn't mean to disparage anyone personally.

Some time ago I read in another forum that cj stopped producing the Premier 350 because they were not making money on it, as manufacturing costs were too high and they would have to raise the price to keep it in production to a point it would not be a good value compared to their tube amplifiers.

Joe, when you get you amplifier check is all the fuses ( B+, B- ) are the correct ones of proper type, and if the RCA connectors are firm. It was one the problems of this amplifier - it the internal nut became loose, the plug would could start rotating and break the ground wire - something that could damage the amplifier, as the body of the connector is insulated from the chassis. Also always disconnect the power cables from the mains when exchanging the input cables or preamplifier. The ON-OFF switch has a poor de-bouncing system, and sometimes switches on again if you do not push it firmly in a decided way to switch off

Other that this the amplifier is very reliable - but avoid shorts in the output. The only protection are the fuses and sometimes a transistor breaks faster than the the fuse. On my 350 I always insert some plastic spacer between the binding posts, as they are very close.

[microstrip]

(...) I assume nobody took their SS amps seriously until they were gone. CJ is known for tube gear and people only focus on that aspect of their business.

Not true, :nono: at less in Europe. Here the Premier 350 received great reviews and critics when it was launched!

I am enjoying it very much. When I first fired it up, it sounded like a wet blanket was on top of the speakers. I knew from the CA200 what to expect, so I was not worried and also knew it sat unused for 4 years, so I just started swapping cd's. Now, OMG! This is a fantastic amp, absolutely incredible and I know it's only going to get better.

Joe,
Congrats on the Premier 350. I know you said it had been sitting for a few years. Do you know actually how they used it before it was "turned off" The reason I say this it may be that the caps are not fully broken in yet. It can take at least 100 hours or more to really open up. Some say between 300 and 500 is when you will start to really hear the magic. If it has been sitting I would say at least 50 hours before the caps are "happy" again.

Enjoy from another 350 owner :music:

Joe,

Is it the system sounding? Still happy with the Premier?

Mike

[Briz Vegaas]

I would like to know about CA200 with a pre vs the 350. It would be an interesting comparison given their similarities.

[lotus340r]

Hi guys, im new here and watching this thread with interest.

Next week i pick up an ACT 2 mk2 and also a premier 350.

I am totally new to CJ and also i've not owned equipment of this level before so am really excited. My last amps in 2011 were Dynavector L300mkii/HX1.2 which were very very good, especially for the price but I am hoping for something a little more from teh CJ combo.

I'm building up the rest of the system from scratch as well so it should be interesting.

That's one fine way of entering the CJ world. I am sure you will be nocked out by this combo. :yes:

[lotus340r]

Thanks guys.

I also have a Tron seven phono stage turning up. Turntable will most likely be a Raven AC or Raven 1 with 10.5 arm.

Not certain on the digital source yet. A few things are being explored.

Modwright 5400 is worth checking out. Punches way above its class.

[lotus340r]

Thanks dpod ? is that CD/SACD replay ?

I am looking for a DAC or streamer. It has to beat a Linn Klimax DS as that's the best i've heard so far.

Yes it is cd and sacd. Modwright was also coming out with inputs via a mod to turn it into DAC

I am using the ps audio perfect wave DAC mkii with USB hard drive wirelessly streaming into PerfectWave. Couldn't be happier. I heard the Linn. Very nice piece for sure.

[joeinid]

Congrats Joe!! Way to go!!!!!

Darrin,

Now I truly understand what you have been experiencing. This is one amazing amp. Explosive dynamics, bottomless bass and that glorious midrange and layering that made CJ famous.

Joe,

How's the system sounding? Still happy with the Premier?

Mike

Mike,

I have been glued to my CR-1's and the Pr. 350SA. Disc after disc, song after song from the many music streams and I am LOVING every minute! There are no better speakers, except maybe the TAD Ref. 1 big brother, but the CR-1's are PERFECT for my room. I really don't need the subs. My kingdom for a GAT :banana:

Joe

[dpod4]

"Explosive dynamics, bottomless bass and that glorious midrange and layering that made CJ famous."

Joe, that is the most perfect description of the Pr350 I have heard. By the way, I picked up an Audience Au24e powerchord and thru the Audience Power conditioner, it opens up the dynamics even more, and takes a veil or two away from the upper registers. I put in HiFi Tuning fuses in the PR350 and that also added more air and clarity. The Pr350 keeps getting better and better!

[lotus340r]

Guys, what interconnect for the pre and 350 do you recommend ? Something musical (not so worried about the hifi sonic checklist IYSWIM) but not too expensive. Maybe £200 ($350) or so secondhand. Thanks, Rich.

[joeinid]

Thanks Darrin,

I've had time to focus on the music ;) It is wonderful. My Pr 350 was in hibernation for 4+ years so I think she needs some break in and time to wake up a little. I sense a slight forward treble but I am not using it under ideal conditions. Even with all that said. This is a keeper, no doubt.

I have found three cables that work pretty well, one of them awesome.
1. Cardas Golden Reference
2. Harmonic Technology Magic Link 2 (especially good if anything in your system is on the bright side and you want to smooth things out)
3. Audience Au24 "e" interconnect is amazing with it...opens up the soundstage and micro detail

[dpod4]

By the way, I continue to be amazed at the understated excellence that CJ builds into their components. Mssrs Conrad and Johnson sure do know how to put all their efforts/time/money into making sure the final product is musical and big big big bang for the buck. It amazes how the Pr350 does so many things superbly that many more expensive amps miss. I think they have nailed the simplicity equation...fewer things in the signal path. Best parts and design possible.

So, you've got some great amps in house now, the Dart and the Pr350. How do they stack up or is it more a matter of personal preferences (Glenfiddich vs. Glenmorangie kind of thing?)

Hi Stephen,

I have to say they are both excellent but I think I need a better matching preamp for both of them. I'm trying to workout how I can get a GAT to try with them. My 077 is superb with anything Burmester and nice with the Dartzeel, maybe not as good with CJ 350. I think the GAT would be superb with the 350 and probably as good with the Dart. They could both be good on the right music. The 350 is an amazing piece but I'm not getting the true flavor because of the preamp, I feel.

[Rafale]

Prem 350 absolutely has to be reborn :yes:

How about the ET5? I have heard both the GAT and ET5 (not in my system unfortunately) and at least to these ears the differences are minimal.

Hi ronenash,

I had the ET5 and wished I had it now. I never expected to come up with the CJ Pr. 350 and sold the ET5 specifically to get the GAT. Other gear showed up in the meantime :yes: and I have not replaced the CJ preamp yet. I'd feel funny buying an ET5 again so I'd have to go for the GAT :thumbsup: I could save some money and get the ET5 again. I did like the ET5 when I had it.

[joeinid]

Update:

I was experimenting last night and decided to replace my Aural Harmony solid silver jumpers on the CR-1's to another pair I had on hand. Bluejean Belden 10-gauge 5T00UP with bananas. Well, the slight brightness I was hearing went away with the Belden jumpers and so did the big, wide and deep soundstage. I guess I'm not going crazy. It's not that bad (soundstage wise) but still noticeable. The silver jumpers seem to be a little brighter with the CJ 350 than the Dart 108 for some reason.

[Puma Cat]

Silver cables can be known to be a on the bright side. Maybe Wireworld makes a nice pair of copper jumpers you could use?

You wouldn't be the first guy in history to have sold a piece of gear only to realize you need it after all. VTSkier auditioned the ET5 and GAT, and also felt that the differences between the two were minimal. Perhaps an ET5 is the way to go. It would save you a lot of money and you could think about a TT to really hear what the Pr350 and TADs could do! ;)

[joeinid]

Stephen,

That's what I always like about you. Very practical. :) I'll have to think about my next move. Just when I think I'm done, I get pulled back in. I still want a better cd player/DAC, better cables/ac cords and power conditioner for now ;)

Joe, You know you want the GAT. If you go back to the CT5, you will always be wondering, regardless of the sonic differences.

I am never very practical :D

If you can stretch it, go for it. :thumbsup:

Understood. Think of it as a process. As the preamp is the heart of the system, I would give that priority over cables, AC cords and distributors. Those bits can be added piecemeal over time to get add layers of benefits as your budget allows.

[bgiliberti]

Understood. ... the preamp is the heart of the system...Interesting comment. I would have said power amp. The power amp seems to affect the sound more to me. Of course, I don't have vinyl sources.

[microstrip]

Understood. Think of it as a process. As the preamp is the heart of the system, I would give that priority over cables, AC cords and distributors. Those bits can be added piecemeal over time to get add layers of benefits as your budget allows.

I fully agree with you. The preamplifier should be the heart of the system. When I had to part with the ART II preamplifier, because it was too noisy when used with the cj premier 350 and my speakers, it broke my heart. :no: Only the ACT2 series 2 was able to partially repair it, unhappily I never managed to listen to a GAT.

Much later an used ART III showed in the used market - happily (for budgetary reasons, surely ... ) it was sold before my heart could take over my brain!

[dpod4]

I was surprised what a big difference to sonic footprint the preamp makes. In my system a VAC tube preamp is more different from a CJ tube preamp than is a VAC tube amp versus a CJ350 in my system.

[bgiliberti]

This with cd player outputs with same cable one into CJ preamp and other to VAC preamp, switching back and forth amp connection to each pre. No phono preamp in the comparison.

The CJ 350 amazes me. Hard to imagine a better amp for less than $25,000 with that type of musical power (600 watts into 4 ohms in one chassis). It sounds really good/best with tube preamp. It will help float the sound almost like a tube amp but with much better punch.

I have a 115 lb VAC amp and I can barely lift it 5 inches off the floor.

[slowGEEZR]

Darrin, if you don't mind, would you contrast the sound qualities of your VAC 300.1a to the CJ Premier 350? Thanks.

[dpod4]

Darrin, if you don't mind, would you contrast the sound qualities of your VAC 300.1a to the CJ Premier 350? Thanks.

VAC 300.1a is clean and pure with absolute harmonic integrity (a guitar sounds like a guitar, a piano like a piano); and soundstage is wide with great floating of images. The CJ 350 is less "airy" with a little more hi-fi to the sound, but there is better dynamics including micro and macro dynamics. The soundstage is not as wide but has more depth/layering front to back. The 350 has more growl and grunt on the low end but doesn't have as much transparency and accuracy and sparkle on top end as VAC. My Maggies require current and watts so the 150 wpc of the VAC come up short compared to stable 600 wpc into 4 ohms the CJ delivers. There is something about the VAC preamp and amp that suspends disbelief unlike any amp or preamp I have heard. There is something comfortable powerful and nonfatiguing about the CJ 350 I haven't experienced with an amp before.

[joeinid]

Very nice synopsis Darrin :)

Thanks!

[dpod4]

Very nice synopsis Darrin :)

Thanks!

Thanks Joe. I believe 2 VAC amps would beat the the CJ 350 but that is 40k worth of VAC amps!

[dpod4]

Thanks Joe. I believe 2 VAC amps would beat the the CJ 350 but that is 40k worth of VAC amps!

And I cant rave enough about the VAC preamps. Magic.

[joeinid]

And I cant rave enough about the VAC preamps. Magic.

When I was younger, I had a favorite dealer (gone now, unfortunately) that would let me "play" with all their gear. They had many great lines and one was VAC. I remember it well. This was a long time ago but it still left an impression on me. So I agree there is magic in those little bottles :music:

[slowGEEZR]

Thanks Darrin! I'm trying to decide what preamp/power amp combo to power my WP8's. I can't get all the various amps/preamps combos in my listening room, due to a lack of dealers in my area. I keep changing my mind on what preamp/amp combo to purchase! I want the pre and pwr amp to be from the same manufacturer. I waffle between Audio Research, conrad-johnson, VAC, and Lamm so much it sometimes feels like my head is going to spin. I want to keep the price below $20K, so used/demo is ok for me. Here are (some of) the combos I've been thinking about:

Audio Research – Ref 5/Ref 150. I wonder if 150 wpc is enough, but I've read that the new Ref 150 really takes hold of the speaker. I would only have to buy the Ref 5 used, the Ref 150 new. I can get from my dealer for an in-home loan, but only if I'm "serious".

The other choices would require each piece be used, in order to stay under $20K. Also, no way to get an in-home review.

Conrad-johnson – ET5/LP275M (or 140 or 125) Great looks and great sound. Downs: Older amp.

VAC – Renaissance Mk.3/Phi.3001a Hard to find a Renaissance Mk.3 used.

Lamm – Various combos appeal to me, but would have to buy older to keep under $20K.

It's too bad that EAR doesn't make a more powerful amp because I really like their preamp.
Luckily, I'm not in a great hurry and hopefully, I'll get a chance to listen to each.

[dpod4]

Hello. Just sent you an email. My experience with ARC is it is lean and treble centered, so with detailed Wilsons, for my ears, that would be too much. From what I've heard about the LAMMs those would be a good counter-balance to Wilsons. Warmth plus detail. Too much CJ may be too laid back; I'm not sure of your listening preferences. I can say without reservation, the VAC Renaissance Mk III preamp is utterly amazing. Without equal. Magic. Holographic. I have heard Shindo, ARC, MBL, ad nasium, and the VAC is, by a wide margin, the best I have heard...regardless of amp being driven, brand...SS...tube.

Linn speaker Kable ?

[lotus340r]

Thanks for the nethusiasm guys. Ha ha puma, yes english through and through.

Yes, its all a bit of a mad confusion here. The linn cable is all I have ! It must be 20 years odl or more. Some mogami is arriving next week. I have a cardas cross on its way for the pre to power and on sunday a Linn KDS/1 arrives which will have its own Linn silver interconnect. I'll have to work on the mains leads then and get a decent block although i'm considering something like the Burmester 948 as well. Turntable to be sorted soon as well, Raven AC in all likleyhood and I hopefully have a local carpenter making me a bespoke rack.

Joe, the obelisk are a beautiful sound, very non-hifi. These are the 1's though and I had the 2's last year and stupidly sold them. Truth be told the Mark 2's are worlds better.

CJ is totally new to me. Its all very exciting !

[joeinid]

The Burmester 948 should help. I need some help in the AC dept. myself. You've done well as CJ gear is awesome. The Premier 350 is a special amp.

[lotus340r]

Guys, just wondering what people find works best supporting CJ gear ?

Granite, slate ? I realise that something bespoke like SRA no doubt gives excellent results but these ar expensive and hard to come by in the uk.

i am using some temporary stands at the moment which seem to isolate the amps from the floor pretty well but when i put my hand on the boxes there is no shortage of vibration. Something tells me i should get the kit as far away from the speakers as possible.

[Puma Cat]

Rich,
For vibration isolation, I am using alight plywood board for my C-J preamp(s) resting on Herbie's Audio Labs IsoCups and Lampblack balls (middle shelf, right)

http://photos.imageevent.com/puma_cat/fujif31andf20photos/EAR324P-1.jpg

My LP70S rests on Herbie's Extra Firm Tenderfeet for vibration isolation, which you can't see in this photo. Both are in a Sanus Euro II rack.

I would stay away from granite or slate; my understanding of what works best is a very light but stiff board or platform, like the plinth in a Rega TT, for example. My Rega P5 and E.A.R. 324P phono stage also shown are resting on a bicycle inner tube inflated to about 10 psi. This works very well for vibration isolation, BTW.

[Briz Vegaas]

I use Nordost sort cones (AC & TC) It's circuit resonance control rather than vibration control so the feet couple with the chassis. My CT5 also sits on a concrete paver, I have a few different pavers and found a smaller more dense paver sounded best ( but looks worst of course).

Some CJ amps have built in solutions with transit screws I believe. I think the 17 is one of them.

Briz,
Have you had any issues with the metal (or whatever it is..) tops of the Sort Kones garfing up the bottom of gear? I'm concerned the material is pretty hard and would garf up the finish of the bottom of the component.

[rthomeint]

The red base under my Premier 11 is a home made base made with 1 inch particle board on the top and bottom with 1 X 2 pine for the sides. The whole thing is filled with sand. I made two these for a pair of Golden Tube Audio SE 40 amp I had briefly. I use the other one under my MV-52 that I use for a center channel amp. These bases weigh almost as much as the amps. On top of the Premier 11 I have a VPI brick which is basically 5 pounds of iron wrapped in a wooden case. Under Mac Mini and the HD3 I have a 3/4 inch piece of particle board painted black and the cones under the equipment are Black Diamond Racing type 4 cones. With a 2 pound weight on top of the Mac Mini for dampening.

Stephen, I've been looking to set-up some isolation control myself...and I very much like your IsoCups/Lampblack solution (so don't be surprised if I steal it :yes:). I was going to look into Boos Block though...and that seems to go against your idea of "light but stiff". Yet you use it for your TT. Can you explain the choices?

[Puma Cat]

CD,
The maple board setup works for the Michell because it's a suspended rather than rigid table like the Rega, so it's got vibration isolation "built-in" as it were. While maple isn't light per se, it's great for reducing resonances.

You can steal the Isocup/lampblack ball idea with pride; it's Steve Herbelin's design. Just don't put the balls directly under a component; they are very hard and can garf up the finish on the bottom.

['cisco]

Stephen.....can you tell me how you placed your Herbie Extra Firm Tenderfeet under your LP70S? peel and stick? just by sheer weight?

Since the CJ CA200 is just shy of 40lbs. ...would you recommend the "extra firm" version? :dunno:

Any advice would be appreciated....thanks
