Best amplifier for Sonus Faber Concerto Home??

I hesistate to suggest that certain amps would give you a more "clinical" sound with the SF Concerto because that would imply that the amps themselves are clinical sounding. But, if you are looking for speed and detail with SF speakers, I would expect Cary tube electronics to be among the least compatible electronics for getting that kind of sound. I personally like Naim electronics with SF (heard the Domus Concerto, the Cremona and the Homage Anniversario run on Naim systems and this was a great combination. They sounded too soft-edged and lacking in dynamics with otherwise great electronics that are less dynamic than the Naim gear (e.g., Hovland HP200/Radia).

I was just kidding about the Crown amp. I find it too harsh for even my DJ service.

You might look into Musical Fidelity as they make rather lean sounding integrateds. There are a bunch of used ones here on the site.

OK,
My next test will probably be with what my local SF vendor also carries:
- a MONRIO MC207
- a Pierre Lurne H1

I have also heard the best for the Manley Stingray, but its not really available for auditioning here in this part of the globe.

I'd think you might want to look into Ayre. Great gear that is perhaps a bit on the "clinical" (whatever that is understood to mean by now) side. And though I'm not a huge fan of either, given your stated preferences MF and Naim are reasonable suggestions especially if you are in Europe. However, I have to strongly disagree with Larryi's suggestion that Hovland doesn't mate well with SF. I have heard that combination and love it - perhaps not the final word in dynamics but not overly warm or soft to my ears. A refined, detailed pairing that wants for very little in overall musicality.

I ditto Steve5725's suggestion that you look into Ayre. I have not looked into their integrated amps, but I generally like their sound. The Ayre gear sounds nimble and very open on top without being harsh or mechanical. Actually, I find a lot of solid state stuff to sound dull and uninvolving and lacking in microdynamics. Ayre's stuff is an exception.
