Sean, I'm having the same problem, with a similar setup. Newly installed SB3, sits < 12 in from the preamp, and < 18 from TT. Moving coil cartridge, and the phono section is inside the preamp. (Naim)
Hum appears to be 60Hz. When I unplug the SB3 power lead, the hum drops 60-70% to barely audible level, can only be heard when the volume is cranked. With SB3 plugged in, hum is noticable easily at moderate volume level, but no music program. Hum is only present on TT input. Prior to SB3 install, NO hum or residual noise was present. I transcribe vinyl often and see the waveforms of what I record, and there is nothing like this in any files pre-SB3. SB3's SMPS is plugged into an outlet within the same room, but on a different side of the room. (May be same power "leg," haven't checked that). Moving the SB3 further away helps, but not as much as unplugging. Thoughts?
