McIntosh MC-501 vs McIntosh MC-1.2KW

So, nobody here has compared??

Thanks to Wireless200 and Jbatlanta. I will go for the
MC-501 as a start.

I´m playing on the SF Stradivari. I have one dedicated 230V/16A line. Before this, my room was 8x7m, there I drove the Strads with the MC-602 easily, never run out of power. Now the room is half that size, so as power concerned, I think the MC-501 will do.
