Amp for Joseph RM-25si ?

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...

Joseph dealer here---

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 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.

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.
