ICEpower Digital Switching Amps?

Justin_time...Thanks for a sensible discussion. I would really like to see a "white paper" with technical details on the various deficiencies of the ICE modules, and ways to correct them. In particular I am puzzled by the reported need for a robust and expensive power supply for circuitry that draws so little current. I will accept reports that such a power supply improves performance, but I really doubt that it is the current delivery capability per se that does the job, and I think that if the real reason is discovered a much simpler and cheaper solution can be found.

If you read what I wrote, I did not say that they "stand on equal ground".

You do not know how many I have sold, or how many competitors amps I have had to analyze (for any number of reasons). Don't assume facts not in evidence. I do not know who or what you are, but you are not a designer of power amps. I know a lot of the "big names" in the industry, and I am certain that their opinion will more closely mirror mine than yours.

As for "robust and expensive power supply", would you care to be more specific? The ICEpower modules require 3 power supplies to operate. Takes up room, costs $ to implement. Even if you take short cuts.

Ar_t, perhaps I've missed your post where you stated who you are, but for those of us reading this thread would you please identify yourself. As a designer/manufacturer of amplifiers, and someone with experience beyond us end users, it would be proper to tell us who you are to legitimize your claims, and to adhere to Audiogon guidelines.

AR T, Sorry about getting testy. If I misread your intentions, you have my apologies. All I can say, is the listeners at my place, and other places, where we have tested a wide array of amps over time, it has been the differences in the new module powered amps, H2O, TacT, Evo, eAR, and others, that have elicited the most starting reactions. Various Pass, Classe, Krell, Plinius, Mark Levinson, to name some, have not been as easy to tell apart.

Can you explain why the ICE 500A module needs 3 power supplies? I would like to see your product line. Can you direct us to your web site? Thank you.

These comments that are made to the effect that........if it doesn't have a big analog power supply like the H20 amps then it's somehow substandard don't jive with me. Linn does a great switch mode power supply amp. JRDG has done the switch mode and conventional power supply and these are all outstanding products.
