I'm still going back and forth between the borrowed Bryston 4B3 and my CJ premier 12 tube monos (140w/side).
Basically the same impression every time. The Bryston has a bit more grip from top to bottom, a bit more tonal precision and clarity (well...tough call about clarity...both sound clear, the Bryston just a little bit more informative).
But the CJ is no wilting wallflower tube amp. It has at least as balls-to-the-wall energy and punch as the Bryston. And it has that "breath of life" tonality, where instruments and voices sound more texturally filled out and present, airy and "there" like I'm seeing through the electronics to the real event.
My dream is to try something like the Conrad Johnson ART amplifiers (e.g. original ART 275W/side, or the new ART 300 monos or ART 150 stereo amp). As I understand it those give the closest to the best of SS and the CJ sound.
I'm also currently playing with a JL Audio 110e subwoofer with my Thiel 2.7s.
Buried way back in this thread, 3 years ago, I was talking about integrating these subwoofers. Yes they have actually been sitting around that long because THAT is how much I dislike subwoofers! :-)
Anyway, it's getting interesting. I've been unable, as was the case last time I tried. to fully keep the midrange and upper frequency character I love about the speakers when using the subwoofer. I have a Dspeaker anti-mode I'm going to use today to see how that helps.
