The noise oscillates on and off about two seconds on and four seconds off continually. The sound resembles the voice of a cricket. It's not loud but it's constantly there intermittently in the background in soft passages.
My components include an old Conrad Johnson pre-amplifier (just checked out by a technician who found no noise,) new Rega Planar 3 turntable, Grado Sonata cartridge, NuForce dual amps, Theta DAC, Oppo BluRay player used as transport and Dahlqust DQ 20 speakers.
There are no neon signs in the vicinity. I don't know any appliances that cycle on and off like the noise does. It's maddening! So much so that I avoid playing records.
