power amplifiers with ICEpower module


Hi guys, what do you think of the new breed of "digital" amplifiers with the ICEpower modules, I mean sonically. My initial thoughts are neither positive nor negative. I think ICEpowered amplifiers are very clean sonically (very low distortion and coloration), but at the same time they are also a bit cool and lean sounding to me. My current reference is a rather low powered (50 W) class-A Accuphase amplifier.

The ICE, Hypex, Evo, EAR, Rowlands, etc. are not "digital" amps. Most of them are class D alright (because A, B, AB, and C are already accounted for), but D does not stand for digital. One amp is classified as class T (tripath).

Here, suit yourself!

With due respect, if the amp you heard is "cool" and "lean", then maybe it is something else because I have a different experienced. Or maybe, the power supply is not a good design.

I too have the ICE H2O. While it is not the "last" amp in terms of everything, it is nowhere near"cold" sounding in my application.

Just my opinions of course.
Dazzdax, you described some of what others are hearing, although some report the $15k Rowland 300 series may not have these drawbacks. Other amps using the ICEpower modules have tended to lacked life, dynamics, weight and immediacy in my experience. Some expensive loudspeakers acknowledged to have excellent dynamics and extended bass didn't sound at all that way at CES last month. I have omitted the names purposely so as to not sound overly critical and hope I have not offended anyone. I'm not familiar with your amp but imagine an ICEpower based amp might be a step backwards.

Essentialaudio, apparently you haven't heard the H2O, or your opinion might differ. My H2O amps outdo my former $16,000 solid state amps in life, dynamics, and immediacy. As to weight, that is a debatable attribute. I know a fellow who auditioned Rowland 201, 301, and 501 Rowland amps in his system before he decided on getting the H2O Signature monoblocks.
An alternate to the ICE module is the TriPath module, for which, unlike ICE, there is a good bit of technical info available on the web. Naturally, the TriPath folk say their approach is best, as do the ICE folk. IMHO it probably depends on what you wrap around the digital control module.

I use CarverPro ZR1600 amps which cost less than 1/4 of what you would pay for H2O or Spectron. The ZR1600 is darned good, and supposedly if you mod it, mostly by bypassing a bunch of input circuitry for pro sound applications, it rivals the best.
Muralman,

Come on Brian, you've read and heard enough from very experienced audiophiles that you know that dog won't hunt.

Amandarae, don't fall for Brian's usual response about components he doesn't sell. He is sooooo predictable.

Many who sell high-end products like Brian are threatened by "digital" amps. They challenge the high-end at reasonable prices (excepting the Rowlands).

ICEpower amps may not be the best amps available at any price, but many, many people who have heard them extoll their virtues as being "full of life, dynamic, with weight and immediacy."

But then again the vast majority of owners and audiophiles who rave about ICEpower amps aren't selling competing products that are getting killed by cheaper and newer technology.
