Amp for Sonus Faber Cremona M's

Im having great results with the AYRE V5-xe. but my cremonas are the originals , not the m's

I'm using Audio Research VS115 with my Cremona M's. I think there is good synergy between the two because both excel in midrange reproduction. I've tried various solid state amps (Classe, McIntosh, etc.), but the sound is a bit too bright and lacking in warmth for my taste. Others may prefer the sound of solid state. FYI most of my music listening is classical and for me, tubes come closer to recreating the sound of live music in a concert hall.

The Burson's timekeeper have an outstanding midrange with soft treble, not fatiguing. Everything gets better once you have 2 units on bridged mode. Worth checking.

I once heard a pair of SF Cremona M's being driven by a Marantz PM-8004, and could not believe what I was hearing - extremely impressive performance. Now I am not recommending this particular amplifier even though I know it will get the job done and costs less than your existing Arcam. But I am suggesting that you check out the flagship of the Marantz reference line, the PM-11S3. At 5K list, its right at the bottom of your budget and I am sure you would be impressed too.

BTW, I drive my 4 Ohm Vienna Bach Grands with the PM-11S3's little brother, the PM-15S2 and am so pleased, I will not be looking for another amp for a long time.
