$2500 Tube Amp Recommendations

Hello
I have a pair of Sonus Faber Concertos (Bookshelf) at 88 Sensitivity
Source is VPI Scout
Granite Audio 770FP (Tube PreAmp)
Vandersteen 2wq Sub

I am looking for a used Tube Amp and want the best bang for the buck.

I only listen to blues/jazz vinyl

Recommendations would be appreciated
