If the steel conduit is magnetic/ferrous, I would consider another option, if possible. In fact, if the in-wall AC wiring is only 8 feet from the sub panel, I would suggest the wiring be replaced with cryo'd 10 AWG Romex, since it might be possible that braided in-wall AC wiring run through a steel conduit is coloring the sound in some manner. I've always considered a tri-braided cable to be an easy way to build a DIY power cord from scratch rather than a superior geometry. my 2 cents

Duster,

Thanks for your response.

It may be a local electrical code issue that dictated conduit had to be used.

IF I had been the one advising the guy I would have recommended he use 2 wire with ground MC aluminum armor cable. That is if it met the local electrical code conduit requirement.

As for what the guy has now I too think his problem is the braided cable installed in the steel conduit. I told him in the thread I thought that was more than likely his problem.

I sent off an email to the guy this morning asking if he had any luck solving his problem. Will see if he responds back.

If he does respond back and the answer is no I am going to recommend he hire an electrical for a day and just run a few new exposed Romex cables just on the floor over to his equipment. The electrician could just install some plastic outlet boxes on the ends of the Romex cables. For the duplex receptacles outlets just pull what he needs from the existing wall outlets.

Yeah, it might cost him around $800 but that's peanuts compared to what he has invested in his audio equipment. Not to mention he has been fighting the SQ problem from his system for a year.
