Audioquest made (makes?) a cable that has rf reduction built-in. I believe it uses a ferrite clamp underneath the jacket. You might try regular ferrite clamps around a decent PC. I would assume you'd get the same desired effect. I use ferrite clamps around all of my PC's. I can't say I noticed a big difference before/after, although I don't have a noise problem in my new house either and kind of brought these along to my new digs. - Tony
