I had a buzz in my Barons which didn't entirely go away when I used the Barons ground lifters (BTW - if you haven't already done so, try lifting only one ground, alternating channel to channel, that might help). Mine went dead quiet when I plugged them into a seperate dedicated line and an old power filter made by Power Wedge especially for amps but I never did get rid of a buzz when the amp was in pure pentode mode - should have sent the thing back to Mesa.
Art, You've got to get out more. At least on my 91db speakers I have 2 tube ams which don't buzz at all - ear next to the tweeter. I've got 2 tube and one SS that do, not counting the MB which I no longer use. :-)
