The smoothest amp you've heard?

You're right it doesn't really make much sense your speakers and room will have 10 times more to do with what you hear than an amp as long as it's used within its limits.

50kHz and 100kHz along with a SuperTweeter to reproduce ultra sonic frequencies is certainly worth considering.

Exactly how or why they would introduce phase shift down to 1/10th the cutoff frequency isn't revealed or explained.

In any case, why just those frequencies? What about 20kHz cutoff frequency causing a 2kHz phase shift?

I have not heard their newest ones, but the Audio Research D-150 is a beast, and accurately smooth as silk on Maggies.

I wish I had 3 of them!

Cheers!
