Confused by ICE applications

My understanding is just the OPPOSITE.
Manufacturer of the module makes the output/driver section and the USER supplies the power....be it SMPS or a nice big Toroid and a large selection of caps.
I will investigate if the ICE modules have an integrated PS. I know Cold Power and IR stuff DOESN'T.
It seems that if you bought a BUNCH of modules and were willing to warranty them, you could pretty much do as you please....change stuff for 'better' sound or even proprietary reasons...My GCC uses GainCell technology on the input side, for example and has some unique (selling point) claims.
If all ICE module users were using modules from the same menu, they'd all sound VERY similar.

Magfan - about half of Icepower modules have built in SMPS including mentioned 200ASC used in Rowland's 102, Bel Canto S300 and PS Audio Trio.

SMPS can put as much power thru 2" toroid at 100kHz as 10" dia, "big nice Toroid" at 60 Hz. In addition 100kHz is not audible and easy to filter out while 60 Hz is audible and difficult to clean. SMPS is regulated while linear power supply is not.

For those interested in the ICE amps, applications and some detail, please try this:: http://www.icepower.bang-olufsen.com/en/downloads/
It is a complete list of available products and some downloads.
Looks like the ASP series comes with on-board power which can also power an 'A' series module....Can you say Bi-Amp?
I am unable at this time to get at the Product OR DataSheets for the ASP series. Hope you have better luck

Just coming to similar conclusions.
Also, some of the 'd' amps run at 400khz which makes it even easier to filter out..
I'm sold! My GCC is a monster and Easily has my Maggies at full potential.
Now, about those pesky fuses!

Magfan - there is still some residue (about 1%) of 400 kHz but it is not harmful. Switching transients were already removed by output filter and 1% residue of 400kHz will radiate at 1/4 wave if speaker wires are longer than 615 feet.
