Well and here is my two cents. I have an MC2000 driving a pair of Alto BE's, I tried Halcro, AR, Levinson. 6 years later, the bias still doesn't need to be reset... they are not on the "MK14 version", and the midrange is to die for. So, it looks cool, it has the best midrange I have heard personally, and I haven't had the tube blues. What's not to like? I added a subwoofer to make up for the loss of base, and I haven't heard Alto's sound better. Is it a bargain? Compared to what else I heard, I would have to say yes. Don't know about any other Mac though.
Cheers!
