Digital Amp's

My Pass had zero feedback. These days, zero feedback is not an unusual thing. In fact, there are "digital" amps that employ zero feedback.

"I wonder about zero feedback amps. Haven't heard any. has anyone? How would you characterize their sound vs. the new digital amps?"

Woodburger- Muralman1 is correct,the Tact M/S 2150 have no negative feedback.

Muralman1- did you get a chance to check on those parts?

Muralman1, since I have seemed to ruffle some feathers I have only heard in my system the 2 class D amps I mention above in my post. Of those 2 class D amps I auditioned, my class A amps have a wider soundstage, better front to back imaging and deeper bass. As I also mention in my initial post the 2 class D amps are excellent amps but I happen to like my class A amps better.

Understood. No worry, we are all preened. :)

Muralman1. I do not doubt your statements here however, it would be appropriate here to qualify the speaker you were using to compare the two topologies and keep things in perpective.When you mentioned "None preferred the class A amp" over the ice amp..... Driving an Apogee Scintilla with any amplifier regardless of the amplifiers topology can be a compromise at best and certainly not an appropriate analogy here. Perhaps the very reason you elected to choose the H20 to begin with,no? Futhermore, what class A amps were you using for comparison? Most of us are aware that all amps are not created equal regardless of topology. While I have never heard the H2O, I have heard a few other ice amps and like Faziod....I wouldn't put them in the same leaugue as the better pure class A amps out there.
