Are there any easy ways to reduce interference from electric sources? (for example have aluminum foil surrounding my integrated amp) I am a college student with his first nice system, and I just want it to sound as crisp as possible. I am up for any unconventional, or otherwise considered cheap/ unattractive ways of combatting my issue. Also, is there anything I can do to protect my speaker wires from interference, or should I purchase speaker wire that has a protective shield? One last question, does anyone have any favorites when it comes to power management? I am just looking for a power strip that can reduce noise for ~$100
