Mike, I've got a bunch of cables you can check out too. I've got two pairs of Zu's best ICs, two of their Birth power cords, their top-end Ibis speaker cables, and a bunch of other stuff too.
The Zu stuff is still available, some of the other stuff isn't. It's kind of sad that even energy transmission wires change models so often, but c'est la vie.
I would guess that with a warmish system, going with more neutral wires could keep things away from the tipping point.
I'd be happy to bring my Signature amps over too, as they will definitely be a different flavor. And, no power cords!
You might have to bring that BPT over some time though!
