I have just got a pair of Sonus Faber Concertino Domus. Now I'm looking for an integrated amp to drive them with and replace my Cambridge Audio 640A, which served me very well, but I believe is not too happy with the 4 ohms load of the Concertinos; feels overwhelmed in the bass deparment, falling short in the tightness department.
What do you think will be a good match?
Any of you owning SFCD? What are you driving them with? I don't intend to add a sub, I believe there is enough bass in there, only the Cambridge doesn't deliver it tight enough for my taste.
This goes for a music only system, no HT duty for them.

Thank you very much,
Alex
