All right, so I moved some stuff around, removed my latest annoyance, and fired the system up again.
My latest annoyance is a Blue Circle Music Ring 1200.
I'd bought it off an AK'er like a year ago but hadn't put it in.
So, when idling, it's relatively quiet.
Put any kind of load on it so that it has to condition the power and it hums like a !#@$)*% &#&*#er. It's supposed to balance the load.
So, out it came, and the plugs went right into the PS Audio wall outlets I'd put in recently during the renovation.
Works much better.
Then I frittered the night away LISTENING TO ONE DISC AFTER ANOTHER. Can you believe that? When I have all these projects and all this puttering to do I'm listening to music.
Harrumph!
