Anybody hear Murano ICE amps?

Elberoth2 I have not heard two ICE amps sounding the same.

-Class D amps are not in their infancy. Our understanding how to implement them is in it's infancy.-

Kijanki,

Can you describe some of the differences you may have heard? Are they subtle or clearly distinct? Do they share anything in common?

I'm very interested in understanding the major differences in sound out there today with this design.

Have you heard the class D amps from Cary? How do these compare?

Mapman - When I bought Rowland 102 I found opinions of others who tested Rowland 102, Bel Canto S300 and PS Audio Trio. My decision was also based on Rowlands reputation and price lower at the time than Bel Canto.

One of reviews of Bel Canto's S300 claims improvement in lower midrange after installation of antivibration cones. Rowland has case made of solid piece (billet) of aluminium - vibration is not very likely.

Dazzdax - Chris, if you read this - how different is your 1000W Icepower from the others?

Apparently a clean square wave in results in a fuzzy, noisy square wave out (of a Class D amp). I'm thinking this is probably not a good thing.

Fuzzy looking step response in the popular magazine's measurement chart is due to the way class D amps operate. Class D is a switching amplifier, with switching frequency in 500KHz and up. The fuzzy oscillation you see in the graph is the switching noise. It is much outside the human hearing frequency spectrum. In short, the switching noise does not affect the sound.
