Confused by ICE applications

Yeah, the 102, 201, 501 and Capri are out of a single billet of aluminum, with all the attaching points machinced in to .003" tolerance. They're incredible. The face plates on the 312 and Continuum are single billets, the sides and backs are billet also, but "only" about 1/4" thick. Rowland was the first with this and now others are copying, even using the same supplier that he pioneered with.

Join the confused club.
PSAudio makes use of the 3 different ICE modules in the GCC series of 'integrateds'. 100/200 250/500 and 500/1000.

What difference would it make if the ICE manufacturer didn't warranty a modfied module, if the Modifier DID?

Specs are *nearly* meaningless and I treat them as 'advisory' only...a pointer if you will.
And yes, DF is also near-meaningless. speaker load as in 'easy' or 'hard' is only part of it. Phase angle, and impedence are also factored in. Add in efficiency/sensitivity and there 'ya go.
Do my panels make much use of hi damping? I don't know and don't care....they sound fine with good, tight bass to the panels limit. While not overpowering, they wouldn't be so regardless of amp used...and I have the GCC250 which is 500 into the Maggies 4 ohms.
There are bunches of applications of the ICE modules and other class 'd' stuff out there.
cold power, International Recitifier, and others. I am currently trying to get my hands on the IR demo board to see what they came up with in the 60/side end of things.

Magfan - IR published paper (google it) on class D with complete design (schematics, PCB etc). Your Maggies are power hungry and Icepower might be a good choice.

I agree. ICE power would and IS a good choice for my Maggies. I use the PSAudio GCC250 to good effect.
I think, however, you've got it a little backwards.
You can buy the ICE modules or the ColdPower or any of 'em and than be responsible for the Power Supply yourself.
The IR unit, for example, needs up to about +-35v, so 5x6v GelCells would work fine.
Oh! I work for IR and have spoken with the designers::

Magfan - why not to buy Icepower modules with power supply built in like 200ASC? Switching power supply, when done right, can be better than linear one (also smaller and cheaper)
