Confused by ICE applications


I've started to get interested in the switch-mode power supplies, but I'm confused by how the various amplifier makers use them. My current investigation is into the B&O ICE modules and Jeff Rowland amps.

From what I can see on the ICE web page, they only sell complete amplifier modules. If that's so, what does JRDG (or Bel Canto) do with them? I'd thought that ICE would supply the power supply and the output stage was then up to the end user...

Ric Shultz was making some ICEPower amps and I believe that he stopped. Maybe he'll sell you an module or two if he has any left, or he can give you leads on where to find them.

Is it just me or Icepower amps have an urgent sound. They sound more hyper-detailed than graceful and relaxed.
Wonderful_electric - I put blankets over my speakers to make sound of my Icepower amp less detailed, gracefully warm and relaxed.

Just took delivery of an International Recitifier AUDAMP7S stereo half-bridge class 'd' amp.
I'll be trying to build a battery operated 2nd system with it.
Unfortunately, it has NO built in PS, so it is either battery of +-55v or so....or the hardway of a conventional or SMPS.
There are NO 'exotic' parts....caps and resistors all appear to be off-the-shelf.
I wish I could post a picture!
Kijanki, I don't know if I mentioned this before, but I WORK for IR, in the 'fab' making power and other semiconductor devices. I have spoken to the design guys and they will eventually make a house call to listen to there stuff in a Magnepan system.
The voicing of these amps was not a major concern though many panel type listening tests were conducted.
