Whats a great amp for Sonus Faber Concerto?


Hi guys,
I bought these speaker used about a year ago, i know they are pretty old. I dont believe i'm doing them justice with the receiver i have them connected to. I'm looking for an integrated amplifier. Which ones do you recommend? I would like to spend $500-$1000. Any amps (new or used) in that price range that would work wonderfully with these speakers?

Hi, I pop in here from time to time.

I own Sonus Faber Concerto Grand Piano and use an Anthem 225 Integrated. The power opened the speakers up more than any other gear I had, Monarchy monoblocks included.

I've been happy with all aspects of the Anthem 225.

Hope this helps !
I've owned the concertos for years and they sing with tubes.
I've used cj premiere 11 and Jadis defy 7.
I have not heard Rogue but there's once currently for sale at the classified for $999. Might be a good starting point
