Default FWIW, Shuguang and Psvane 6SL7 & 6SN7's

I've been using these in Inspire amp for almost 4 years. No issues. Speakers are Klipsch Heresy III's. They simply sound better than any old production tubes I have had.

Sound wise, IMHO, the CV-181-Z is on the rich/dark side.
The CV-181 T is a bit more open.
The CV-181 T-II grey glass bronze base is more open, perhaps a bit tilted up.
The WE 6S*7 and WE 6S*7 is more balanced.
The UK version is a nice tube too.
The Sophia Blue 6SN7 is outstanding but pricey.

The Full Music tubes are also quite good.

Running 6V6 in a triode amp produces what, around 4-5 wpc? That's not enough power for me so those amps aren't an option. My amp produces 17-18 wpc and that's a bit low for my system, I'd much rather have 25-30 wpc. But as long as I don't crank it way up, it sounds great with the 17. I have run it with tubes producing as low as the 4-5 watt range, but that's giving up 6 dB of headroom.

Maybe someday I will find a high efficiency speaker which I like, and doesn't cost $30K. The search continues ...
Ya just never know with speakers. I'm using 6F6's with probably 4W maximum with Proac DT8's. On paper they don't appear to be efficient enough to run with low power. Using them in a small 12 squared room and they go as loud as needed. They are also a killer match, really great combination. The cost is a ways south of $30k!

I like ProAc speakers. I am familiar with the DT8. A medium efficiency speaker, spec'ed at 90db, I read a review which estimated them at 89db. My present speakers are 90-91db, so a bit louder than what the DT8 would be in my room. I've run mine with 4-5 watts, and they are fine at moderate listening levels, but if cranked much at all, there is a definite loss of dynamics and some audible clipping on deep bass notes.

If I didn't have a fairly high-end speaker, I'd give the DT8 a listen. Looks like a very well put-together design. I truly love my present speakers, when driven by my 100wpc or 260wpc amps, they really sing. They are great with my Inspire as long as I don't overly push them. I don't play them as loud as I used to or in a room as large as I used to have. Back in the old room, I twice drove them into clipping with the 260wpc amp.

Much of it truly comes down to personal preference starting with speakers. Speaker tone and types of sound and presentation we enjoy tends to vary from one person to the next. Of the speakers I've heard and preferred (tonally) in rooms larger than 12'x12' most were lower sensitivity, 92db@1w/1m and below. And, when the particular speakers made a memorable impression on me they sounded their best (in most cases) with good solid state -OR- tube amp(s) with at least 25wpc. Improved dynamics and better driver control won me over and 100wpc tube amplification with the right amplifiers can sound great too.

With all the speaker talk I'm sure some here have tried or own what I have, the Omega Alnico Compact Monitors? They're 94db, I actually feel they need more power than the sensitivity rating alludes too. With my Fire-Bottle I have to run kt88 for 12wpc to really feel like they're being fleshed out with good dynamics.

My end game for speakers is the Omega Super Alnico High Output XRS, they're his top of the line tower speakers with better sensitivity rating at 97db. Not only would I be getting the extra speaker for bass, but the better sensitivity would increase that performance flat overall. They're $5k tho so not sure when I'll be picking them up...

His Alnico Hemp Cone drivers produce the most organic and gorgeous mid range I've ever heard. Not that there isn't better out there, surely there is, but the Omegas house sound is exactly what I like. Unfortunately the Monitors I have produce nothing of impact under 50hz, of which I'm sure the towers will fix. Someday...

The Proac speakers have very flat impedance which makes them a great match for lower power amplification.

Interesting. I was considering The Omega CAM's.

FWIW, I've been using Klipsch Heresy III's for 6-7 years. They are 99db but the impedance dips to 4 ohms. In a 14 x21 room placed in corners the bass was adequate. I moved in with the GF and in the present room I could not place them in corners and the bass was as you describe with the CAM's. I added a HSU VTF-2 MK5 sub and the bass was back in spades. It was easy to integrate, is very tunable and the 350 watt amp is fine with efficient speakers. I thought I might need 2 subs and called HSU. The rep thought one would be fine and he was correct.

Perhaps a sub or two from Omega may be the ticket?
