Kgturner,
If the buzz is coming through both speakers at the same sound level, then I don't see how it would be a problem with the amps. Each amp would have to have the same problem. Not much chance of that. You may be right about your speakers being so efficient causing the problem. My speakers are only 88db. I think the problem could be solved by sending the Malbecs to me!
