Maybe this will help you to better understand the issues. It's part of my post from another thread, but applies here:
Even though it's a little off-topic here, I feel I should explain WHY (very genrally speaking ;~) tubes seem to be better than transistors at 'preserving' an audio signal: it is in fact because of a tube's SHORTCOMING as an 'electrical valve' - it is slow to turn on and off (like a light bulb.) And so there is some 'overlap' as one tube (of a pair) hands the signal off to the other tube. Transistors by contrast, are extremely high-speed devices which turn on and off instantaneously -- and if a pair of gain stage transistors are not PERFECTLY (and laboriously) matched, there will be a little time 'gap' as one hands off the signal to the other, where some subtle parts of the signal will be lost.
Unfortunately, many audiophiles believe that electrostatic speakers require gobs of current (NOT) and so drive them with huge solid state amplifiers. Thus missing out on the enormous pleasure their electrostatic speakers could provide! They need only stop and remember that the amazing Quad 57 was, from the very beginning, driven with a low-powered tube amps. Later on, no solid state amp has ever been able to improve their amazing ability to reproduce the human voice.
Thanks for your kind indulgence ;~)
