Speaker Wires on Carpet


I was reading that carpet will interfere with the signal going through speaker wires if the wires are on the carpet. I was wondering if the amount of interference varies depending on whether the positive and negative wires are twisted together versus running straight and parallel to each other. Also, will certain types of wire jackets cut down on interfence?

I ask this because I have wires running next to the base boards on the floor in my (carpeted) dining room since that's the most unobtrusive place for them. I may consider some type of wire elevators if they are reasonably priced and look nice.

Thanks in advance for any advice.

Would glass also work as an isolator? I was browsing in Pier 1 and saw some glass knickknacks that were about the right size and shape (and price) for running cables over.

"I was browsing in Pier 1 and saw some glass knickknacks..."

I was watching an episode of Wild Boyz in Kenya and saw a little dung beetle rolling a perfectly round turd while doing a handstand, and I thought the exact same thing as Tony!

Brilliant minds think alike.
It's called thinking outside the box. The relevant issue is the isolation properties of glass. (And that glass won't stain the carpet, like the substance you propose.)

So...back to the original question. How is glass as an isolator?
Get them off the carpet. Period. One way is to buy those little Rubber door jams in a hardware store. Another way is to but elecrical Tape and turn it on its side. You dont want the static nasties of carpeting spreading their venom on your cables .
