Dear Gregadd: You take an old review, nine years ago, and take a tube amplifier at it's best low limit on output impedance against a SS amplifier in the low-top worst case on output impedance.
Still in that way we can read on your link:
*****" The top trace is the Krell; the bottom, offset by 1dB for clarity, is the Connie-J. It varies by about twice as much as the Krell, reaching ±0.25dB. The tube amp's more depressed top two octaves were audible as a very slight lack of air. " ****
Regards and ejoy the music.
Raul.
