@bdp24 : Yes, I bought a NOS RM-200II from Music Reference shortly after Roger passed. I had a few conversations with him over the phone prior to that purchase, and some more via email. He asked about my specific system, listening habits, room size & set up, and associated equipment. He was very generous with his time, answering all my questions, asking me questions, and it seemed like he was truly interested in getting me the right fit(s). He told me how he specifically created the RM-200 for Magneplanars and other such speakers. But during those conversations he hinted that he held the RM-10 in higher regard overall. He told me that the RM-10 should be fine driving my Magnepans taking all that I told him into consideration. It was hard for my brain to accept that the 35 w/ch RM-10 could drive my large speakers adequately. I did buy a used RM-10, but I used it in another system. A year later, I bought the RM-200II from Tony at Music Reference and I was very pleased. I lived happily with that amp in the system for awhile until a power tube went & I didn’t have matched spares (ALWAYS keep spares!). I put a vintage tube amp that I kept as a backup in the system as a stop gap so I could listen to music. The amp is a HH Scott LK-150 (~60 w/ch). It sounded awesome in place of the RM-200, and the 60 w/ch was plenty for my room. That made me feel compelled to place the RM-10 in the system. Could this little 14 lb amp drive these giant speakers? Yup.. sure did. And as wonderful as the Scott sounded, the Music Reference was even better! When the new tubes arrived for the RM-200, I installed them, biased the amp, and left it in the system for a few months. It, of course, sounded great! One week when I was on “staycation” I conducted a 3 way amp shootout. The 3 amps all sounded amazing to me, with the RM-200 on the “almost too SS sounding” side, and the Scott on the “almost too tubey sounding” end. The RM-10 was right between them… “just right”. I’ve used a bunch of amps with several Magnepan models over the past 35 or so years, and this is about the best sound I’ve had in my house. I once had a Krell KSA-250… I should’ve never sold that one. I’ve been chasing that feeling of satisfaction for years. I believe I have that feeling now. As I wrote earlier.. I bought the Speltz Zeros so I could “light load” the RM-10 as Roger suggested. In the end, the man was right on. I should’ve taken his hints as an endorsement. He was clearly not trying to “sell me”, but steer me in the direction he thought was right for me.
