Yes, I follow all of Delof's guidelines and will stress the importence of keeping the left and right speakers cables as far apart from each other as possible, even when they are close to the amp.
Cable Arrangement Suggestions
How do you arrange all your interconnects, power chords, and cables to avoid/minimize interferences? Cheap suggestions especially appreciated. I have a home theater set up with cables for AV receiver, DVD/CD, RPT, two powered Def Tech towers, extension chord (for the far left speaker and cable tv amplifier), a cable tv splitter w/cables to the VCR and tv, VCR, cassette, LD, minidisc, and will be adding a DAC shortly. I have Radio Shack RF blockers on all my power chords. Other suggestions you've found useful?
