I totally agree with Jeff on this amp.
I have had it in my office system for about a month and it is an awesome little amp. I replaced two Trends 10.1 amps with the Winsome. I have also played around with the Charlize, Sonic Impact, and a Monarchy SM70 in this system and I believe the Winsome is better than all those amps in my configuration ( Computer, Hag USB, Modified Bel Canto Dac II, Morrison Elad, Winsome Amp, DIY Speakers, DIY Sub).
There is just a bit more headroom with the Winsome and I think the mids are what make this amp shine. It doesn't run out of gas quite as quickly as the other Tripath amps listed since it has more power. Obviously you can run less efficient speakers with this amp than the Trends.
Anyway I have been happy with the purchase and definitely would recommend it to others. Besides kit was fun to put together as well.
