Coupling Banana Plugs

OK. Since the couplers have uninsulated metal, make sure of course that the two couplers used for each channel cannot come in contact with each other, or with anything else that is conductive or grounded. You may want to wrap them with electrical tape.

Good point. I used some clear thick spiral wrap around the metal.

For your rear speakers, there's really no reason to use expensive cables. A spool of Audioquest or Monster should be all you need. Use anything more than that, and I don't think you'll be able to hear a difference.

Zd542, Swampwalker, thank you for your comments.
I had about 25 feet of Kimber 8TC and found another 18 footer used. This second set replaced a cheaper 20 foot pair.
With the cable now all the same, I found that it did increase the output and the sound quality.
