ICE power amps are all apparently a little different. But, that being said, they have more in common than BIG differences.
My PSAudio uses the same ASP module as the W4S 500 ref'd above so I'd expect 90% similar results with only very subtle differences.....many of which may simply be wiped out by a change in speaker wire or interconnect.
Keep in mind that module is ONLY 200rms FTC method and the 550 is only good for 60 seconds. The nature of real music makes that fine. As a note, the full output in the big ASP module as used in the REF1000's is only 30 seconds.
I like my 1.6/PSAudio combo. The only problem I had, which I suspect is more speaker than amp is it is a little 'hot' on the high end. I fixed that by rotating my panels in place, putting the pole piece to the listener NOT the Mylar.
