I have been using the MCX-2 in my DEMO System for some time, and thought it quite good.
But.....Recently upgraded my PrePro and have concluded that I had been under valuing the MCX-2.
With the new PrePro the sound is simply stunning. And of course the AMP is now able to show what it was capable of all along.
I would also think that ALL the MCX Series amps have been "in the shadows" and deserve to be talked about with some of the best amps made.
