Digital Contamination of the Power?

Wow! Interesting experience for you George. I wonder if just a good quality power cord can take care of the noise or if one needs to actually employ some other device to inhibit the back contamination from the digital sources? That's all for the responses.

Keithmundy,
I use Shunyata Ztron Alpha digital power cords. Shunyata make these solely for digital components to alleviate the problems discussed so far. And they work very well in my set-up, compared to the non-digital cords.

Jon2020hi.
Sorry to say but a power cord won't stop the digital noise or switch mode noise rubbish from entering the household wiring, and if your hi-end gear is close to it, the airborne rubbish as well.
It emanates like a cancer through the wiring and through the air.

Cheers George

George,
Agreed. The power cord may not stop all of the hash but it does reduce it somewhat to the point of being significantly audible. We do the best for SQ with what we can have and what works, even though the problem is merely partially solved.
Cheers! J.
