Stranded vs Solid Copper

djones51.. I’ve used small diameter copper tubing as a spacer in the past.. works great because you can custom make your lengths.
As for some of the other comments.. I’ve built a number of homes myself and have functioned as my own electrician under a friends license. Not particularly worried about burning the house down. Just trying to get a good solid connection for these new power cords I recently purchased.

You can use Wiremold, would look a lot neater IMO than EMT tubing. Use the starter box over the outlet, then run the channel housing the bare conductors along the wall on top of the floor moulding and up to a Wiremold surface box that holds the HG receptacle.

Thanks for the very good suggestion. Looks like they have a product to hide the vertical tv cables.
thanks

Not sure how the sound is affected between solid and stranded but the best thing for HIGH current is stranded because of the skin effect of AC voltage (it actually travels on the outer layer of wire). 

This is I know from being an industrial electrician. 

Myself Use Verastars excellent high purityCopper foil speaker cable,and Silvergold alloy foil interconnects . A flat foil has more surface area then  equal size awg guage wire.and very thin diaelectric. That may why it sounds very balanced . I have had several very good brands for me this is high enough 
in quality without breaking the bank.
