Shunyata Venom PS8 - Loud Buzz - How much current..........?

I removed my RPG 600S and decided to try out the Shunyata Venom PS8.
I have 2 sets of Bel Canto 1000 monoblocks plugged into the Shunyata PS8. The Defender is plug in as well.
The PS8 is plugged right into the receptacle and nothing else is there.

Loud buzz even when a single amplifier is plugged into the system.
No change in the original configuration. Power cord is the Pangea.

Its a little perplexing and not sure what could be the issue.


I think the smps inside Bel Canto 1000 monoblock is not collaborate with the Shunyata Venom PS8.  
Hmmm thanks for that input, you could be correct but its still bizarre and might have to probe more on that, thank you much
