Hi there,
I'm having some issues with my over all Hifi setup.
My Turntable going through the CA 540P Phono into the NAD 326 Int Amp and produces an electrical buzz/noise. I can hear this on the speakers and on the headphones, in particular on the Dr Dre active headies. when I first got the Phono amp I thought it was to blame so I got it replaced but same problem. I also notice when I touch the back of the phono amp the noise changes slightly.
I haven't put the record on yet, meaning the power to start the motor.
Here's the weird stuff:
1.When I disconnect the RCA connectors leading from the TT to the Phono amp the noise disappears.
So I think it must be the TT?
2. RCA are connected from the TT to Phono amp and I disconnect the power supply from the TT, the noise is still there.
Conclusion??: It is like the electrical interference is switching between paths, so when the TT is off the electrical noise goes through the RCA connectors and than through the Phono amp. What I don't get is if the TT's power supply is disconnected where is it picking up the noise from because when I take point 1. into cosideration? Yes the TT is grounded using the Phono Amp's grounding connector.
Ok to put the spanner in the works: I just got my Caiman dac and it also has this noise/buzz. When I touch the back of the Dac in particular the RCA plugs the noise disappears. I use my Dr Dre headies (it picks noise a lot more) and the noise is in stereo, now, when a track starts playing the noise shifts to the left can, dims slightly and is still audible at low volume.
I took the Dac to another room with a Mac, plugged it in and the same issue.
We've only moved into this house in March, It's a federation style Semi, however the Electrical box at the front of the house looks fairly new.
So do I have some weird electrical grounding issues or what?
Please anyone?
