RE: The NAD is contemporary with a Dynaco Mk3, is it?

"Better caps provide more transparency and top end resolution." Your comment. Since tube amps use better quality caps than the typical SS amp, doesn't that mean a qualitative edge for a tube amp over SS?

I also thing you're attributing things to me that I have not said. I have said that the higher source impedance of tube amps does interact with the impedance of the speaker to form a frequency dependent voltage divider. However, I have also stated in this forum that it only works with a speaker who's impedance varies by 4 or 5 to 1 from minimum to maximum. Your electrostatics are not a suitable test. If you doubt this, look at some of the amplifier tests in Stereophile, where the interaction shows up clearly in the amp's frequency response when measured with a simulated speaker load. It's a premise that is well proven and follows from basic EE theory. John Atkinson wrote an article on it, and it was in their archives. I can e mail you a copy if you can't find it; but I'll need your current e mail.

However, that's not enough. Even if you EQ out that frequency response shift, (and I have) there is still some remaining difference in the sound. I'm simply suggesting that the inherently better caps might be part of the answer.
