06-04-06: ArniI have auditioned NuForce Ref 8 and CI Audio D100 and D200 in my system. I don't know if they are ICE based amps.
Tvad,
I have read an Nuforce owner argue (Audiogon thread) that it was more musical and warmer than the Conrad-Johnson SE60 it replaced. Have you ever listened to an ICE power based amp in direct comparison to the type of amps you believe are "better?"
The NuForce Ref 8 that I heard in my system...and the NuForce Ref 9.02SE that I heard at the LA audio show this weekend were less warm than any tube amp I have ever heard.
Honestly, I believe warmth is a product of distortion, as the distortion fuzzes up the leading edges - among other things - and creates what we consider warmth. That in combination with attenuated highs.
Since digital amps have such low distortion specs, and have such wide bandwidth, I find it difficult to believe that they can be warm in any sense of the traditional audiophile definition of the term.
It's somewhat system dependent, I'm sure.
I'd have paid someone at the LA audio show if they could have pointed me in the direction of a demo room with a warm sound. The Acapella and Wilson rooms came closest. Even the Lamm room was not warm, although I liked the sound.
