Can Music Reference MR9 drive Tannoy DMT 215 II

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.

If the speaker specifications are correct(sensitivity) then these speakers can be driven with any 'good' quality low power amp(5-20 watts).High quality transformers and power supply mean more than mere power-watt ratings.I don`t believe you`ll ever risk clipping with your current amplifier even at very high sound levels.Your ears would give out before the amp does.
Regards,

I am just having them on the floor vertical and bases to bottom. Preamp I' used Supratek. Sound so good that I have to put all other speakers away for now. Only one problem is that there is a soft hum on both sides. Not to sure why but never had that hum on other speakers. Is there anything wrong with the Tannoy or the MR 9? Yours must be so quite Jburidan? How many inches from floor to the monitor? I am trying to build my own.

Found another issue is that the bass kind off too boomy, which putting mid range and vocal back. All I can think of it could cause by monitors sit flat on floor. So will try to sit them on the footer that off floor about 8 inches may help.
@ Clio9 and Charles1dad, thanks!

Very high sensitivity speakers (like yours) will easily reproduce ANY noise present in your system. Tube amps and preamps generally have some hiss present and occasionally some hum too. You might try lifting the ground with a cheater plug on the amp just as an experiment but it sounds like the hum is low in level and normal given your mix of equipment. If it's not too intrusive I wouldn't worry about it. The other speakers you were using were not likely as efficient as your current set which is why you didn't hear the hum.
