McIntosh MA 7900 impressions/experience?

I have an NAD M3 driving the new Bryston Mini T's and am looking at getting a McIntosh MA7900.

Want to hear people's impressions of the 7900 and how it would better or compare to the NAD M3.

Other suggestions? Please provide insight on the Mac. I need pre-outs for subs.

I have Mac separates and love them in my home theater - haven't heard the new integrateds from Mac.

Thanks for the help AGon
