Music Reference RM9 - user comments please


I am considering of getting a used RM9 for my Merlin-TSM, can any user of the amp comments.

"transparent and neutral presentation" seems to be his design goal, with no apologies to SS, but with the bloom you can only get with tubes.
I have had some people tell me they prefer the MkI versions of both the RM-9 and RM-10 because in their opinion they had more tube characteristics to their sound while the MkII versions sounded more like solid state. I think that is the knock on the RM-200 as well. It is pretty obvious that the MkII versions of the RM-9 and RM-10, as well as RM-200 sound characteristics will never be confused with classic CJ or Cary, but all three still sound like tube amps to me, and very good ones.
Clio09 – thx for the impressions. Yes I have read reports in the past about preferences between 1 and 2 versions. It really helps when you are close to the manufacturer for repairs / upgrades.

Well I just completed 3 years of what could easily be defined as analog Lunacy - so heh - why not use that as a lead into some Amp/Preamp Lunacy now.
Thank you for the link.
I owned an RM-9 mk I for 10+ years and had Roger replace the on/off button (most failed) add mk II chokes and move the fuse holders to the top plate. In many respects, I sadly regrets selling that amp. The El34 Seimen tubes in matched Quads from RAM Labs were remarkable and had a midrange magic that was fantastic on several pairs of Merlin speakers I had/have owned. I wish I would have kept amp.

Highly recommend output and V1 V2 tubes from Roger. They sounded the best and not be a little I may add.
"I sadly regret selling that amp." You don't know how many times I have heard former MR owners say that... fortunately it is still easy to get RM10s.
