If most class D amps use either the Ice or N Core Modules, can't one assume that amps made with either of those modules will pretty much sound the same? I know that various designers monkey around with the input stage and power supply, but an N Core sounds like an N Core and the Ice sounds like the Ice.
I have listened to roughly 6 or 7 Class D amps including the NAD Masters series, The Wyred4Sound amps, the Channel D, and others I can't really remember the names of and none of them even came close to the Odyssey Stratos Extreme which is in my system. The 2 words that come to mind is listener fatigue. Not in my system, ever.
