'Lucky'? I was looking for a tube amp that had any kind of reasonable specs (low distortion) and found the popular brands did not even come close.
To avoid distorting the source material beyond recognition through speakers with any kind of accuracy, <0.1% THD over a 5-50k frequency range is needed. The ATI line of SS amps for instance spec at <0.005%. I think the Cary line is pretty much 1-2% (at 20hz-20khz). You do the math.
You like a 'warm' soft sound? Put cotten in your ears. It will accomplish the same thing. Really.
'Supposedly, there exist a few triode amplifier designs of exceptional transparency. Usually their power output is below 20W and insufficient to drive most speakers' (Seigfried Linkwitz).
The very low distortion Hafler DH-200/220, Muse 160, ATI, (and Bry$ton or the really $$ Jeff Rowland) solid state designs start looking good about now.
