Chris, let's hope you get some wires soon then. I think you're in for a treat. :)
I do not agree with going single-ended from pre-amp to amp. I have the 6010D and 8011AM's myself, and I find that a balanced connection is quite beneficial. The noise floor is even lower and I find the overall presentation a bit more relaxed. Perhaps subtle to many, but having tried both I for one can't go back to RCAs.
I'm currently running a Precision Reference XLR between preamp and amps, and that's a brilliant cable indeed. Be careful with Apex between preamp and amp - Synergistic says many people find the Precision better here so you might want to borrow both if you can, and compare.
Waiting for the Apex speaker wires myself, hoping to get them soon so I can give them a good workout! I've tried both Acoustic and Precision Reference speaker wires and they are both very good but not balanced enough for me. Since the Apex is in fact both these cables in one, it might be what I'm looking for. I find the tone of Acoustic superb, but compared to Precision it is lacking in speed and detail. Precision on the other hand is very detailed, extremely fast and airy, but also a bit too bright and lacks the warmth of the Acoustic. The combo should be perfect, I hope.. ;)
