Dedicated Line - Things to consider

We have two breaker boxes, the original, which is fully loaded with breakers, and a second added later that is closer to the street that has a few breakers in it. I ran 125 feet of 8-gauge multi-strand from the stereo location in the living room to that panel with a 20 amp breaker and put a 20/30 amp outlet on it inside my entertainment center. (My surge protector has a 20/30 amp plug.)

From the 20/30 amp outlet I ran the 8-gauge to a pair of hospital-grade outlets located just outside the entertainment center. The run is continuous and there are NO breaks in the lines between the various outlets. There is also a big ferrite bead over the wire where it comes out of the panel. Even the hospital grade outlets accepted the 8-gauge wire without problem.

This had the effect of removing "high-end hash" from my Yamaha Universal Player. It did less for my Oppo95, and I attribute this to a better power supply in the Oppo.

@toddalin  , I take it that you are in the "one circuit camp"?

I got a good deal on the wire and one circuit was all I needed.

It's just semantics, but a lot of these posts would be easier to read if they were worded a little differently. Most professionals don't think of wiring as originating at an outlet in a room and going to the electrical panel, quite the opposite.

As a DIYer nonprofessional I apologize and I'll try to remember this in the future.
