I had this problem with my phono section in my active preamp (a forte2.. I know, I know, not a very good preamp)when I moved and there was a radio station transmitter about 1 mi. away.. drove me nuts! finally when I bought a separate Benz PP1 for my low output benz mc, the problem went away! apparently this benz phono unit is much better shielded? I was going to try mu-metal shielding inside my other preamp.. would this have worked? I tried aluminum foil around interconnects with no effect.
Hearing local radio through speakers
I just bought a Rega Cursa/Maia and Planet for my B&W 602s with Audioquest Diamondback interconnects and Monstercable speakerwire. It sounded fantastic. I then took our christmas tree down and i moved my rack about 2' to its normal place. The only other thing i did was coil up the power cords (stock) with a rubber band. There is a local radio station tower about a mile away but i never heard this until i moved my system. Where do i start, Cardas caps, High $$ powercords?? Thanks and happy new year.
