To pick this up again, I've tried both the Panamax M5300-EX line conditioner and Mapleshade power strip (Mk II Plus) with the same result. Starting with the Focal speakers and Dell monitor plugged into the conditioner/strip, if I plug the computer into the old style console the electrical noise is inaudible until I hold my ears tight to the speakers, and even then it's light. But if I plug the computer directly into the conditioning unit or strip, a high pitched hash/buzz becomes audible from the listening position (3 feet) and at times is even like soft music audible between the speakers. Of course, using the the strip gives a bit more clean and delicate sound than thru the console (MAC HC or Venom 3 for speakers and computer).
So I'm wondering, is there a way to solve this short of a regenerator or a specially built PC. Thanks,
