Best cables to be used for pass labs X250.5, XP10

Best power conditioner and ac cables to pair up with the X250.5, and the XP10?

I have Pass XA100.5 and XP20. I use Harmonic Technology Magic balanced cables. Pass suggests using balanced mode and short, thick speaker cables with their amps. In my case, I use a long IC and a short speaker cable. I don't have experience with other cable brands in my system.

I own the Pass X-10 and the Pass X350.5 and I am using all Synergistic cables.
Check out my system posted.

I have the Pass XP-10, and tried various PCs on it. The best I found was the DCCA Source II cord.

I posted a thread abt AC cables w/Pass amps, if you do a search...The verdict was that AC cables don't seem to make a huge difference, but going into the wall directly was better than into a line "conditioner."

I use a PS Audio Xstram Statement and like it. It's kinda like adding a subwoofer.
