Can Music Reference MR9 drive Tannoy DMT 215 II

No problem. I drive mine with Art Audio Jota HC monoblocks with 22-24 watts per channel depending on choice of output tubes. Bass response is superb. With 100 tube-watts per channel, these speakers will blow out your eardrums before they ever clip. You're lucky to own the 215 DMT!

The sensitivity spec says 104 Db/2.83V @1meter. That is a loud speaaker! Seriously you could probably drive these with any amp you wanted to use. 100 WPC is more than enough headroom, I would think, to avoid clipping. I agree with the others.

Thanks alls for advices. I did try the RM 9 for few hours last night. It sounded really good. Amazing! I only listen mostly Jazz, Classical and some easy listentings so would never go to loud. I also monitor to make sure the power transformer stays cool and it does. I have read Jburidan post ran it with Art Audio Jota HC. (It is a beautiful amp!). @ Jburidan, thanks and I just want to make sure not to clip that why I am seeking for advice.
I was going to use it with Rotel RB 1090 but I just got hooked with tube. Taking advices seriously, I will stay low at volume to avoid damage the Tannoy.
Aloha

You're welcome, Kinhoang. I bought a pair of speaker stands from Sound Anchors. The proprietor has a set of 215 DMT drawings, and he makes sturdy custom stands for the 215s. Mine are mounted vertically with bass drivers on the bottom and port holes on the outboard side. Speakers are toed-in slightly so that the lines of sound converge just behind my listening chair which is about eight feet away from the speakers. This set-up was recommended by Peter Lanzilotta, who is a recording studio guru. It's amazing to think that many of the greatest recordings were final mastered on these very speakers that I use in my listening room!!!

Also, I have used 300B SETs with 8-12 watts on these speakers with no problem. But the Jotas do a better job controlling the bass.

Enjoy :)

Roger Modjeski measured my old RM-9 on his bench and we could easily see it was putting out close to 125 watts per side. That should be more than enough for what appears to be very efficient speakers.
