New dedicated lines have high noise floor.

Great feedback everyone.  Much appreciated.  I took the hospital grade MC cable recommendation from my electrician.  Jim, I think I need to read that passage several more times to get the gist of it,  I have a call into my electrician and will share the wisdom found here.  Thank you all.  I'll let you know how this turns out.  Pete 

Jea48, the 2 circuits are parallel on the panel.  Is that an issue?  The panel is a relatively new (9-years) 200 amp panel.  It is full with no additional slots.  I've got another 150 amp panel next to it which is also full.

Sometimes audio components sound far better on the same star grounding scheme. So by splitting your system across two separate lines back to the breaker box, some type of ground loop issue is occurring.

Have you tried feeding everything using the one power point, and does that make any difference?

Re: Hospital grade wiring, I would ditch it. Hospital grade does not mean good. For example hospital grade duplexes means a duplex that can withstand constant water splashing from cleaners washing the hospital rooms each day. In order to not corrode from the water, the metal in a hospital duplex must be all nickel plated, which is the worst sounding plating for audio systems.

This is a good example of how 'hospital grade' is good for its stated application, but awful for high end audio.
