Shakeydeal,
The same gear is why I say you may not of had the synergy with the Sonic Frontier amp. It's that simple. I'm running a Meridian cd, Sonic Frontier Line 3 SE and Sonic Frontier Power 2 with upgraded tubes etc. with Audience cables into Harbeth speakers and think I'm in audio heaven. My initial post was because I have a Rel Strata iii hooked up by the specs from rel and was curious if this was correct because my research suggested I should have a hum coming from the sub if the amp was a differential and that the black wire fed to the left negative speaker location of the amp. This is how it was set up with no hum.
