Thanks for all your suggestions....I'll have to give Chris a call or shoot him and email and will check out the Virtual Dynamics site. I am hoping to avoid complete replacement of the breaker pane and taking apart of the whole system to find the problem.....
I have an electrician coming out to check out that everything is basically copacetic, no DC leak, good grounding, etc. and make sure the microwave, big old plasma, refrigerator and other bloodsuckers are properly isolated and supplied. THEN talk to him about a possible subpanel for any of the above in some combination and a dedicated, conditioned and grounded line for the audio......
Someone has suggested that 12g is the way to go rather than 10. I would think 10 in and 12 out makes sense, but have no expertise. The 3 outlets will likely be Avatar Acoustic Afterburner 8....
Thanks for all the help and I'll take any more you might have!
Enjoy the tunes!
