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....

My feeling, rightly or wrongly, is that well designed stereo amps do, for all practicle purposes, separation as well as monoblocks - with much of the theoretical advantage being more part marketing than real improvement, except in the case of poorly designed gear with poor cross talk performance. Of course, you do need monoblocks for high power tube applications - got to put all those tubes somewhere:) I too am using light loading, can't here much (any?) difference so if it is easier on the tubes, less distortion and more linear output, why not. Roger's repsonse to me had nothing to do with mono versus stereo, simply said I might (might) get more bass output if I went with the RM200, he was not leaning towards a move to the mono option - but, I have not heard it, so....
I sort of feel that way too (I do use Atma-sphere monoblocks as well, in the colder months:), and also us various Quicksilver monoblocks). My hesitation with pulling the trigger is that like Clio9, the manufacturer was very hesistant to make any such claims for the benefits of going mono; which gives me pause since it would be an easy sale for him. Boy.....
Anthony, I sometimes wish Roger did not put that darn mono swith on the unit:) Oh well, I think I might manage to leave good enough alone (for now). Now if I could get my hands on some NOS Mullard EL84s......
His stock EL84s are Ei? When I bought the amp he was "raving" about the Genalex Reissues, you might want to give them a try in 10,000 hours - $100-120 for a matched Quad from Jim McShane, a bit more from Roger.
Well, since the Merlins are 8ohm, 6.5 min (VERY EASY TO DRIVE)I feel that much better with sticking with 1. I like and believe in the idea that, other than power output, fewer power tubes sound better than more output tubes in the circuitry. Along with my belief that lower powered versions of any circuit will sound better than hiogher powered versions - unless you need the power.
Anthony, can you hear any difference between using the 4 ohm and 8 ohm taps with your Audiokinesis speakers?
Ecclectique. love your note, and I think you are right about
looking at tubes rather than going mono. I will have my eyes
out for some NOS to "play" with. I never heard any
type of Amperex tube I did not like. Since posting, I've
been listening to a lot of music through the RM10 (with my
Lightspeed Attenuator)and it clear to me that Anthony
(Clio9) and Roger Modjeski are right, stick with a single
stereo amp in my situation. I am going to give the GE a try
when I can find them from a trusted tubemongerer. Ooops!
found them at Brent Jesse $80 per pair, not bad. Well get
some.

Cheers! Paul.
These are the original 1960s grey oval plate GE tubes. These are not the round plate?
The GEs are in the mail. Clio9, you sticking with the Ei 12ax7s? Roger and Sal seems to advise that.
No, not yet. What price should I be able to get a quad for? I take your $100 price was for a matched pair?
