Keep removing the various Barnacle bits attached to your NAD CDP until it becomes obvious which Piece is is the problem (junk)
Follow Ups:
I removed the NAD a couple weeks ago; was using it as a transport. Right now, the noise can only be heard when the ARC CDP is being used. It has always been coming from the ARC.
But, the Tripp-Lite Isobar has reduced the amount of time that the noise is present.
Unplug the ARC ?
First try it sans the Power Magic filter/conditioner gizmos.
Not convinced those things give benefit. possibly they are interacting?
Dunno though as I've never used such and My setup dead silent..NO noise whatsover. Same as when unplugged.
And I did Zero to get it there.. besides decent gear.
Have experimented for many months...
All power conditioning was removed, tried different power cords, cheater-plugs, the only components plugged into dedicated line were amp, preamp, and ARC CD, unplugged the ARC and noise was gone. (The ARC is SS, not tube).
The noise was eliminated when I had full system hooked up and ARC was plugged into a different receptacle and circuit.
I'll see what happens when the isolation xfmr arrives.
**But a new development yesterday; turned on the tube preamp and the noise/interference was present. Preamp was turned off overnite, so noise from CDP was present on cold start. DAC was unplugged.
Thanks to everybody for their interest.
