I heard the Mc can setup at RMAF. MEH. Wasn't overly impressed. I felt the Oppo setup (cans and amp) sounded quite a bit better, but a hell of a lot less money. But admittedly, the Audeze LCD-3's sounded best to me. I tried lots of little tube headphone amps, and they were nice, but limiting in features compared to the Oppo headphone amp - which also sounds great.
The Mc stuff looked good, had good power, but the price of the combo was a bit high comparatively given its sound. YMMV.
