Confused by ICE applications

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.

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::

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.

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!

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.

Yep, been in touch w/designer. He had to tell me about the 'bridge' switch.....basically 2x juice MONO! Can you spell 's u b a m p'??
My first (guess / intent / urge) is to go with 4x12 gel cells for each rail....This will give REAL clean low ripple power and allow me to hear it at its best and perhaps also allow the sound of various power supplies and associated components to be fairly evaluated.
I suspect that with appropriate hi-sensitivity speakers, no need will ever apparent for more than 2x20 watts....which with appropriate speakers will drive you out of the room. 5amp hour batteries will provide 60 watt hours so should be enough for several hours of LOUD listening. Actually, 50v at 5amps is 250 watts, x2 rails.....well, you can do the math! I'm just confusing myself.
Believe me, I've read the Hypex / ColdPower stuff avidly. This is what got me started on this kick in the 1st place.
I was even thinking of springing for a HYPEX power supply and the 180 transformer. Should 'bout do it?
If I could post a picture....can you post here? I'd setup the macro and get out the AlienBees (lots 'o light, trust me) and take a few pics.
My buddy at IR is pretty helpful and one day I'll have him over for a listen and some Single Malt.
My PSAudio GCC250 really likes the Maggies.....it should be a fun comparo:
