Music Reference RM9 - user comments please

Now tube rolling:)

I have some nice EL-84s to roll in that amp. I will listen to the RAM tubes first though. For 12AX7 I have some nice GE 5751s I'm going to try too.

I asked the question on another forum, you ar sure the 5751 is perfectly ok in the circuit? One thing the RM10 doesn't need is more gain, so I would think that would not be an issue.

I don't see why not. I'm definitely going to try it for the same reason you're considering it. I get my amp Thursday. I'll let you know if it blows up upon use of the 5751s.

FWIW - I have a Berning Micro ZOTL I'm using as a preamp right now. It comes with 12AT7 tubes, but I have been able to use 5751 and 12AU7 with no issues. The 12AU7 lowered the gain the most. I may even try 12AU7 tubes in the RM-10.

Well, I still own the Music Reference RM9 Special Edition, I still love it, and I don't think I will ever sell it. After a few years, I starting missing my RM10 MKIIs, and bought them again this week - if 35 watts is enough power, it gives the RM9SEs a run for their money (the RM9SEs are 5x$$$).....

You know, with the Merlin VSMs it just might be that the 35watts from the RM10MKII is all I really need. I am even thinking of maybe selling my RM9 Special Edition, if I could convince myself I would not have instant buyer's remorse and the fact the Special Editions never, ever seem to come up for sale as Roger only made 16 and I get the feeling most owners will sell it at an estate sale. But, the RM10 is one hell of amp in my system.
