Thank You, ml8764ag. I will retain the info. Down the road I may go with the Music Reference amp., but its really hard to say for sure. Every time I come up with a set of components I may consider for my next system, I come up with another set of workable synergy and technicaly compatible components that I like.
Yup knghifi, Roger Mojeski is one of my favorite hi-fi designers (a few others being Richard Vandersteen, Jim Winey, and Bruce Thigpen---guys whose products offer very high performance at their price points). I met Roger when he did a seminar at Brooks Berdans shop, during which he discussed the design of his then-new RM-10 amp. After the talk I asked him if he recommended that amp or his RM9 (nice score ml8764ag! Assuming the RM-9 Mk.2 you just acquired is the one that was here on Audiogon last week.) for use with my old Quads. He asked me what I was currently using, and when I responded a pair of Quad II originals and a Bedini 25/25, he asked me why I thought I needed a new amp for the Quads, that the model II was a real good one for those speakers. A manufacturer discouraging the purchase of one of his products?!
I really respect how Roger works on the design of his products for years before bringing them to market, fine tuning their circuits so as to make subsequent updates/mods very rare (not to mention repairs), their ownership therefore not a constant drain on ones bank account. He also designs for long tube life, running them very conservatively. The RM-9, still competitive with contemporary offerings from other designers, went through only one design change in over twenty years, from the original to the Mk.2. Same with his current RM-200 Mk.2 (a really creative piece of engineering which achieves around 10,000 hours of life from it’s two KT-88/KT-120/6550 output tubes per channel, creating over 100 watts per!) which has resided in the Class A/Tube category in Stereophiles Recommended list since Fremer reviewed it 2011. The original RM-200 had also been there during it’s time, gaining an underground reputation of being an over-achiever at it’s modest price. The Music Reference amps, especially the RM-10 and RM-200, also have a look of understated elegance that really appeals to me.
I wish I still lived in the San Francisco Bay Area, and could therefore enroll in the Audio Engineering course he teaches there!
congrats on getting the RM9. I happen to own an RM9 which has been significantly modded; an Rm10 and also Rm3 -Rogers crossover box, which is not being used right now.
The RM9 has amazing transformers, I base this on xx? years of listening, and also comments from the respected hot rodder who modded my amp.
I have put it up against OTL, high power SS amps. I am hard on my gear meaning it gets used a lot and for long periods.
With the KT88 tubes my Rm9 rivals SS bass, and yet it is delicate and smooth like the OTL's were in the high frequencies. I have it powering matrix 800's.
