Digital Contamination of the Power?

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.

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.
