Amp for Joseph RM-25si ?

Are you looking for tubes or ss?
Anything over about 100wpc will work great.
Manley Snappers and Gamut D-200 amps work particularly well with mine.

I would be looking for tubed amplification. It sounds like you are bi-amping your setup. I have a Forte amp I could use for the low end. If you are bi-amping, what changes did it bring to the overall presentation?

I had these speakers for many years with CJ tube gear--very nice combination. I briefly tried them with a Plinius integrated and they also sounded nice but they pair well with tubes.

Not bi-amping. Just an example of two diff. Amps that work particularly well with the rm25s.
I also have a 50wpc push pull Canary Audio amp (ca339) that works great with them.

Bnrlaw, thanks so much for your responses. Your amp choices look intriguing, and the Gamut D-200 is new to me, although I see the reviews of it are very favorable. Have you found a particular cable/IC to work better than another with your Manleys or the Gamut? I would also like to read what other RM-25si owners have experienced when they bi-amp...amps, cables, imaging, frequency response, etc. I have heard it can really make these speakers sing...

On the tube side, I've had great results running Manley Snappers, Rogue M-180/M-150 and Cary 120s MKII amps.

And if you would consider a hybrid amp, the Rogue Medusa does a very nice job also.

I am using a Butler hybrid with my RM25xl's, so it should work with your 25si setup. I thought the Bel Canto 1000 amps were real good, but drum's were TOO good for everyday use for me.

I used the Speltz cables with the Joseph's with an old Carver amp and they were Ok, but when I used the Bel Canto amp in the same setup, the Speltz were terrible. FYI. Never tried the Speltz with the Butler.

Always have used Analysis Plus oval 9 and oval 12 wire.
Tried it briefly with Auditorium 23 cable but liked ap better.

Thank you to all who posted a response to my question(s). I have tried the AP Oval 12 and found it to be a well-engineered, cost effective and great performing speaker cable. Between cable changes and room placement/toe-in the Joseph's are sounding much better.
Thanks again.

I’m running a BAT SS amp and tube preamp through my JA Pulsars. Amazing sound. Check out BAT.

@pix4work — You might want to talk to Don Sachs about his tube pre and/or amp (KT88).  He was refurbing and modding vintage HK Citation amps and such until he decided to design his own stuff.  He says his pre/amp significantly outperform the mods he used to do on the vintage gear, which apparently was already pretty good.  He sells direct and his prices are very reasonable given the refinement and parts quality that go into his electronics.  He could probably give you a good idea of what kind of improvements you might expect with his products given his familiarity with vintage equipment, and the kicker for you is that I believe he uses RM25s in his own system.  Just FYI and FWIW. 

Thank you rlb61 and soix for your responses to my post. Great cable, IC’s and attention to speaker setup can unleash the potential lying dormant in a system. I will be enjoying these changes for a while.

soix, I am intrigued by your comments on Don Sach’s tube gear and will be checking it out. FWIW, the vintage HK tube gear was really ahead of it’s time and is worth following up on, as well, and thank you for mentioning it.
