How can I check that I do have an indep., 20amp circuit installed for my "equipment closet" ? That is what I had specified for the electrical work in my basement, not sure the exact terms, I would have to look at the paperwork, whcih I don't have with me.
I think the electrician screwed it up because (a) he messed up a bunch of other things (he's a real idiot poor guy) and (b) when burner, a/c stuff starts it creates a sound/hum on my system, very weird. On the latter it looks like (but careful I am no electrician) the electrical draws caused by the heat system has a sudden, brief impact on the audio of the system ...
Also, if I use an amp with my Denon 3810, it introduces a hum. I suspect this might be due to the receiver. The receiver using only its own amps is absolutely silent. The amp is a Cinemax 5.
(btw, I was never able to tell a diff in SQ between with and w/o the external amp, stupidiest money ever spent !)
Any hints pls ?
