Primaluna Dialogue Premium Integrated driving Magnepan .7 with Bypassed Fuses

@classic8 : Hello… I had MG-1.7s, and now MG-3.7s driven by a Music Reference RM-10 amplifier (35 wpc), and I listen to music in a slightly larger room than yours, at slightly higher levels with no problem at all. I’m enjoying some of the best sound ever with this combo after many years of using Magnepans with many different amplifiers. You should be just fine. Incidentally, I bypassed the fuses in my 1.7s for years without issue. I haven’t done so with the 3.7s. Happy listening!

@classic8 : One caveat I’d like to mention… I use Speltz Zeros to double the impedance that the amp sees, and I’m using the 8 ohm output taps. I didn’t notice a big difference in sound, but it made me feel more comfortable with using a lower powered amp with low impedance speakers (electrically). 

@classic8 : You’re welcome! To be clear… I used the RM-10 with the Maggies without them with no problem, but chose to buy them to make the amp/speaker synergy a happier one. Also, the designer of the amplifier (Roger Modjeski) was a strong advocate for “light loading” his (& other) tube amps. That would’ve been impossible without the autoformers. 😉

@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. 

@bdp24 : Yes, I’ve read many of your posts over the years. The RM-9 is an amp I’d love to try one day! Also, I’ve been considering possibly getting my hands on a pair of the ET LFT-8b speakers that you and others have written about… but I don’t have any complaints about my current set up, so why fix what ain’t broken? The RM-10 is definitely a special amp (imo), and I would recommend it to anyone who values quality over quantity. Within its limits, limits which have proven to be surprisingly broad, it’s hard to fault. The OP described what I consider to be a great environment for this amp. I’m sure the Prima Luna he asked about would be fine too (in terms of power), which is what prompted me to chime in. 

@classic8 : I’m very glad to hear that you’re enjoying the sound of your system. In the end, that’s the most important thing, isn’t it? I’ve found Magnepan speakers to be special… not everyone’s cup of tea, but special for those who appreciate what they do differently from conventional speakers. Also, after reading your initial post, I strongly believed your amp would power them well. Happy listening!
