monko, In this case, the OP had a problem well known to owners of the lower end of Rega turntables; hum that got worse as the cartridge approached the motor. Ralph offered the standard correct solution. No hi-fi rack and no amount of separation between TT and amplifier will fix that particular Rega-specific issue.
Rega Planar 3 hum resolve.
So, I called my local stereo shop to find out if Rega got back to them about my Planar 3 tt.( they've had it since Sat.) I noticed a hum that got more noticeable the closer I moved the tonearm to the spindle. Well turns out they sent my stereo shop a new tonearm which should be here tmrw or Sat. So hopefully that's the fix!
