Contrast/compare 50W tube amps

I've not heard Atma-Sphere. I found the BAT to sound clean and accurate, but didn't hold my attention. I just couldn't get into the music. The DeHavilland has a beautiful, refined sound, but they are too polite for my tastes. The Quicksilver Triodes will both slam with rock, and sound sultry with jazz, or vocals. I think they would pair up well with your speakers. Don't get me wrong, the BAT and DeHavilland are very good. And as is always the case in this hobby, it's a matter of personal taste. I just felt more snap and life to the music with the Triodes.

Hope that helps. Good luck.

Thanks Boa2, I understand that Mike builds these as a "custom" product $5800).I don't suppose these come up for sale very often?? The 6-C33C-Bs were always one of my favorite tubes.Any exposure to them used in an OTL?

Boa from reading your critques, it seems confusing, as you are prasing each, yet you say "its just not for me".
I prefer to give all the negatives and any positives about an amp/speaker and let the reader make up his own mind.

I wonder how you would feel about the Audio Research VS110?
"Oh its great N all, but not for me".
Whereas I come out directly and put the point directly, its too grainy, distorted and presents the music as if a smoky film were covering the music.
Plain and simple based on 3 speakers with it, Spendor 8, Cabasse Jersey, Magnaplanrs 1.6.
In spite of the fact that the ARC amp/pre combo placed a smoke screen over the music, I still was neither impressed with the Magnaplanrs nor the Spendors.
I just come out and say my opinion, there's no confusion at all, its direct. The reader can take it whats its worth.
Oh btw the California Labs cdp in that system may have put its cheap sound into the results. What a cheap sounding player that is. Did knowing to resolve the Audio reserach distortion.
They wanted like $3500 for that KT88 amp!

I'd have to disagree with the assessment made about the Dehavilland GM70.I run the Alon Lotus Sigs,open baffle,2001 model.They give tight quality bass,midrange in the you are there,and a very extended top end,the choice of tubes and interconnects can change the sound to either side of neutral,and will also dictate how much warmth.I play classic rock,jazz,vocals and I must say i'm very happy with the sound in MY SYSTEM..YMMV

of your list, quicksilvers are the ones with the magic. check cj, mac, arc, vac, and music reference as well, if a tube amp or amps is your destination.
