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...

Magfan,

The point you raised yesterday was the heart of my question. I'd seen the www.icepower... link and thought to myself: if everyone is using the same modules, won't the amps sound the same?

Kijanki and Dcstep have a partial answer: the lower cost Rowland gear is apparently similar or identical to the competition (say, Bel Canto); however, the higher cost Rowland gear has more modificaitons and may sound different.

I wouldn't expect Jeff Rowland to give precise descriptions of any modifications he makes to an ICE Power module when he uses it, but I would like a general sense of why his products are different than some other company's that uses the ICE Power units.
Dave,

Thanks for the report on JRDG equipment. I knew from past reviews that Jeff pays attention to things like case design (Stereophile made special note of it in their review of the Model 2). However, I've never been able to look into one of his components and the "official" web is mum on the modifications and particulars of the application of the ICE units. So, thanks again for spelling it out, that's exactly the information I was looking for.
