Sonus Concerto

I'm trying to upgrade my system.I have Classe Cap 151, Classe Cd .3, Mit T2 double bi-wire and SonusFaber Concerto. I'm looking for the best amp (used) that mates with my speakers and matching cd (used) that run direct to the amp.Any suggestions?
nobody will help? I'll help, come have some scotch we'll discuss this topic
Were you unhappy with the match you have? I own a CAP 151 and was going to purchase concertos this week.
