The Music Reference RM-5 Mk III (tube) preamp mated beautifully with my RM9, also has a killer Phono section. I replaced it with an Audio Research LS15 (tube) & PH3(tube) phono preamps. Cost twice as much, sounds better (not twice as good though!), and of course, now I have a remote!;)
Music Reference RM9 and Preamp Experiences
I would like to hear about preamps that RM9 users have tried and had good success with (I own a RM9SE). RM200 users proabable are somewhat relevant as well. So far I have used a Joule LA150MKII, the MR PiaB, and currently using a Dodd Battery Powered pre, but - as always - am wondering if there are other units I should give serious ocnsideration to. Thank you.
