georgehifi, I completely agree that the Bel Canto REF600M sound nothing like Icepower. By the way, I certainly don't remember seeing any review of the 600M by Clement Perry. audiotroy may be confusing with an older model. The 600M are a Ncore implementation that is customized by Bel Canto.
And then, on top of that any of the Bel Canto Black products take it to another level and is much higher end than their e.one series. Plus, with Bel Canto Black, such as the integrated amps, you also get a superb DAC and firmware updates too via Ethernet. Their Ethernet implementation is outstanding and makes for a simple solution for the customer that also sounds incredible. Plus, I find the Bel Canto Black EX integrated to be just slightly warm of neutral, analogue sounding, detailed, very powerful and musically involving. Nothing has driven the ATC SCM40's in my room to their level of current performance as the Bel Canto Black EX integrated. The T+A PA 2500R before that did a pretty good job, as it is a nice piece, but not in the league of the Bel Canto Black EX. Others that have heard both in this system completely agree.
