As F1 wrote I believe the issue with my Odyssey Dual Mono has something to do with the grounding scheme. Could it be with your Krell too?[/QUOTE]
I suppose that it could.
But the Drednought is supposed to take care of that problem, and I believe it does.
But then there is the operator error factor........
We might just be doing one little thing wrong somewhere.
Are you hooking the negative terminals on the Dreadnought to the negative terminals on the SDA??
I am doing that, and read somewhere on here that that was fine.
But that is my most suspicious connection in the system.
