I put a 1" copper tube on the IEC of my ARC CD3MKII. I got it at Lowes for $1.88. I didn't hear any difference. I suppose I could get my money back. I won't tell them what I used it for.
When I was a kid, people would put tin foil on their rabbit ears (TV antenna) for better reception. That didn't seem to help much either.
