one lives in medium-high density housing. It helps that we live way out in the country (tranquil village of about 40 homes.)
After using a few AC filter devices over many years, I decided to experiment by going back to basics. That is, no active/passive filtering between mains wall socket(s) and AC cable entry into audio components. I assembled an ultra-thick-copper-rail mains distribution board and invested in Cardas and Zu Audio mains cables.
Inside some components I installed small-medium AC line chokes and improved RC networks on outputs. Also I modded components with optimal power rail and other filtering, but with minimal device count, plus shortest signal and DC path, allied to premium internal cabling. One theory is that RF/inductance is best squashed/quarantined nearest active devices.
Also I've found that chassis-lined internal shielding can be most beneficial, having tried ERS and adhesive pure copper tape.
What I've found where we live is that music dynamics, in particular, seem to have an unrestrained dimension which was not as pronounced with previous external active/passive mains filtering. I'll be sticking to this "unfettered" method now.
Nonetheless, Al, I certainly agree that mains and other forms of unwelcome electrical/telecomms/wireless/extra-terrestrial interference are best avoided. They can affect audio performance drastically. Enjoy the music!
