My brother would like to change from a valve power amp to ss. He has no intention of changing his DCS Rossini or Estelon XB speakers. His VTL 200 has had to go for repair and has purchased a Quad 909 on here as a temporary measure, so is in no rush to get a replacement. Easy to get a dem would be Vitus, T & A, and Constellation, but also considered Pass Labs and Boulder. Has many know, getting dems is the biggest problem. Has anything passed him under the radar which would be a good match. The Estelons are not a difficult load and budget would be £10k with a little flexibility.
