Is this with your turntable and cartridge hooked up, or an open input? Are there any nearby WiFi equipped devices? Can you make a recording of the noise and post it here?
I do have bunch of WiFi stuff about a foot away. The flutter goes away when I unplug the WiFi stuff or even if I put my arms around around the Eros with the WiFi on. How much distance would be needed to eliminate the noise? Any kind of shielding?
