Amp for Sonus Faber Cremona M's


I'm looking at upgrading my system and I think my speakers are going to be Cremona M's. My current amp is an Arcam A28 and that is obviously not an ideal paring for the Cremonas. Does anyone have experience with what pairs well with Cremonas? Budget wise I'm looking at something in the $5000-$8000 rage.

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.
I've posted this before, but here goes again. I'm using Pathos integrates in mono-block mode. I've had this set up for a couple years and think the Pathi and Cremora M's work very well together. If you can, give this combo a listen.
A used MC252 (250w/ch) is the lowest powered amp I would recommend. A used one can be had for $2500. A very nice amp - replaced mine (my first Mc amp) with a McIntosh MC452. My speakers are Sf Cremona Auditor Ms and REL B1 sub-bass system.
