I have demo'd the McIntosh and thought it sounded very good. Very warm, great mid-range. Obviously, it is "colored", but in a way that is very enjoyable. It is an amp that will maintain some value (esp. if bought used), so there isn't much risk in trying one in your system. I would have bought one but don't have adequate space or ventilation.
I have never heard an RM-200, but was very interested in buying one and did a lot of research. It is relatively light, generates a fair amount of power, and supposedly does not get very hot. But in another thread in Audiogon, those who had heard it said the RM-200 sounds a bit more like a solid state amp than a tube amp, and recommended buying a used Moscode 401HR over the Music Reference. (Both are in fact hybrid amps, not pure tube amps.) A dealer who carries the Music Reference echoed the comment about the solid-state sound sig of the Music Reference.
As far as Roger Modjeski, he seems like a great designer and a nice guy. However, he seems to be a one-man show, so if he goes out of business you may have trouble getting the amp serviced and resale values will fall. Additionally, I found Roger to be difficult to reach by phone. It seems like 4 out of every 5 phone calls go straight to an answering machine. That ultimately discouraged me from buying his amp.
