IMO both your speakers and amp are your weakest links. You are a tube guy so IMO I would stay away from Sonus Faber, these speakers tend to be a little dark and tubes won’t help lighten them up. If you like tubes, try out the rogue Cronus magnum II with kt-120 tubes. I used to own 1 and they are underrated.
if you go tubes, try some ushers/Wilson’s/others that are not so dark.
