Music Reference RM Mono?

I am using an RM10 MKII (35 watts) with my Merlin VSMs (89db, smooth, high impedance)in an 18x12 ft room. Listen to jazz at moderate listening levels (I think)- it plays plenty loud with 35 watts. I was wondering if I would get any significant improvement by buying another and running them as monoblocks with 70 watts given the type of music I listen to and the size of my room. Any Music Reference lovers try the monoblock congifuration? Better? In what way? I'm think another 3db is volume isn't going to make any difference to me, but....

I have no experience with the RM10s, but I had a similar situation when I went from a single Monarchy SM-70 Pro to using two as monoblocks, driving 90dB Von Schweikert VR-1s in an 18x14 room.

The monoblock configuration was better in every way. The best way to describe it would be "effortless". The additional headroom makes for better bass, more vivid midrange, and smoother highs, all without changing the fundamental sonic characteristics that I loved in the Class A SM-70s.

I believe that the reason for the difference is that the two channels don't have to compete for the power supply. As for you, the ability to play 3dB louder was a non-factor for me, and I think that most of the monoblock advantage would remain even if the monoblocks only made the same power as the stereo amp channels.

For me, it was revelatory. I'm guessing monoblock RM-10s would produce the same results.

I think Roger is a scholar and a gentleman, having owned one of his EM7s at one point. However, I'm guessing that amp designers don't necessarily have the same priorities as we crazy audiophiles, hence his very practical answers to your and Clio09's questions.

If you're already using monoblocks, then you already have a pretty good idea what the answer is for you.
