How to decide if your system needs conditioning is the big question. Some thoughts:
1) If you see an improvement late at night.
2) Turn your volume up with nothing being played. How far do you turn the volume before hearing "white noise"? In my case I hear nothing even inches away from my speakers until the 12:00 o'clock on the volume. Since I listen at 8-9:00 them EMI/ RF is probably not a problem.
3) Try a "noise sniffer" sold, I think, by Quiet Lines or Audio Prism. If this thing has no noise probably not in your system.
Vrsola, you can get a mini-stealth for $499 from one of A-gon's "approved dealers". I forgot which one. They normally retail for $599. It is a 2 outlet version of the Stealth and the mfg'r told me identical in every other way.
