I have the T8's (current set-up is CJ PFR pream w / Ayre V-5xe amp). Someone that actually sold them a while back (as part of the Hales line)informed me that they best they ver sounded was when they were driven by the Classe' CAM-400 monoblocks. He suspected that the Large BAT's (SS) would also be a good match. He recommended lots of power.....which I disagree with but there you have it.
I know you desire tubes. One option might be a used VT-200 (ARC).
