I have heard it at my dealers but can't pass judgement on it yet. He has offered me to bring it home to campare to my MC402, but I won't do that as I can't afford to trade even if I liked it better. And I really haven't heard it in a comparison to anything other than the tube amps. But I did like it's sound through the Wilson Sophia 2's. It makes me wonder what it would do in my system. I would say it is sure worth your investment in looking at it.
