@blueskywalker ,
Ignore the snarky response above.
If I were you, I would PM John Rutan (audioconnection). He sells AQ and knows his stuff- and he won't try to sell you something. Tell him what your situation is and I bet he'll be able to guide you.
After that, contact AQ directly. They answer the phone and can help you, too.
Much depends upon your equipment, as well as you power lines. So, it is hard to pin down exactly what will work in your situation.
From my limited experience, AQ is building some seriously great cables these days.
