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.

Maybe an ET250S might be good enough

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

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!

Bob

Where does it say it has teflon caps?

certainly not in the spec's

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.

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.

Here is the link to the Roy Gregory HiFi+ review of the Pr350:

It does mention the use of Teflon caps....

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.
