sweet, euphonic, reasonably powerful tube amp?

Usblues - The room is a standard suburban living room with wooden floors, rugs, various furniture, sheetrock walls, and windows on one side, treated with Marigo dots. Domestic issues limit my ability to fiddle with room acoustics. The speakers are on the short side, on either side of the fireplace.

Those of you that recommend Quicksilvers or the Mac 275, first, thank you, and second, have you heard these amps in comparison with ARC or VTL?

Many thanks

Rodman - My VT100 is a mkiii, so I'm stuck with the 6H30. I'm reluctant to roll NOS tubes in an amp. Tube problems with an amp can be a bit more dramatic than with a pre-amp.

Pubul57 - Thanks for the thought about the CJ's. I had an MV75a 25 years ago, then tried a Premier 4 and thought it was too bright. Haven't tried anything since. I gather that EL34 tubes can generally be softer and more laid back? What CJ's do you recommend?

Thanks

Drastic - Thanks for your comments about the room, but as I tried to indicate previously, further work on room acoustics is not possible, for domestic reasons. Further, as noted, I've already treated the windows, the floors are covered with rugs, there is a fair bit of sound-absorbing furniture in the room, and oil paintins on the walls. The room is not ideal, but equipment I've heard in showrooms does not sound substantially different than in the room. I think the real issue is this: My ideal for hi-fi sound I'd like to listen to is mid-hall Carnegie Hall, and most equipment does not lean in that direction (and the same is often enough true for recordings). And, indeed, you're quite right, I AM trying to use not only the amp, but every piece of equipment I own, as a tone control, in the broadest sense (encompassing timbre, top end, bottom end, etc.). From time to time, I see comments that suggest that there is something wrong with that, and I just don't get it. It's as if there is one only one absolutely correct and ideal system sound, and if my system deviates from that, then I'm doing something wrong. I don't buy into that for a variety of reasons, but that's another thread.

Semi - Thanks very much for letting me know about the BAT vs. the ARC. I'm glad to hear of someone who's heard both. I've wondered if I might like the BAT 75 non-SE better than the BAT 75SE? I understand the SE extends the treble, etc., and am fearful that I may find that less to my liking.

Lissnr - Thank you for your comments about VTL - but I'm puzzled. As noted, I'm now listening to the VTL ST150 (which I think is 6550's) in triode mode. It's really very good in triode mode, I must agree. However, if I'm finding that to nevertheless seem a bit on the bright side, wouldn't I likely feel the same way about VTL's EL34-based gear? That assumes there is a "house" sound for VTL, but maybe the EL34-based gear sounds a bit different?

I'm in the process of looking into older CJ's, by the way. It's been on my list as a possibility for a year or so--now might be the time.

Many thanks to all, and I'm looking forward to any further suggestions.

This has been a terrifically helpful thread and I thank all the contributors.

Today I bought a 2nd hand CJ Premier 11, which I'm having sent to Bill Thalman to upgrade, etc. So I will experience what I guess would be a "mid-period" CJ sound, which should sound different from the VTL and the ARC. If it doesn't work for me, I'll try something else.

That having been said, let me ask the EL34 fans, what are some of your favorite EL34 amps that have the lush, warm and inviting sound to which you refer? (Maybe I should have bought one of those...and maybe that will be next...who can't help but be attracted to the notion of "audio as warm bath," after all?)
