I recently picked up the S300 (stereo amp version, 150wpc into 8 ohms) and have been burning it in for the last week or so. So far so good...and IMHO better than the Bel Canto eVo2i integrated amp (although I'm driving it with a tubed preamp, so that accounts for some of the differences).
I'm going to be hosting the December/Holiday NY Audio Rave in December, and I think we're doing to be continuing on our digital amp theme that started last month...so you can look out for comments then.
