Looking for an Integrated Amp / SF Signums

I have a pair of Sonus Faber Signums on adjustable factory stands. My listening room is 24 X 26 with a lot of glass. I don't want to buy something that would lean me to upgrade anytime soon. There is a lot out there in various price ranges. What would be a good sound amp for these speakers? Budget dollars would be between 3-4k. Thank you in advance for your input!
