"My only concern / curiosity is that I am "starving" or "short changing" the woofer by splitting up the 8TC through internal bi-wiring, and adversely affecting the sound because of it.
I may look into "renting" an internally biwired 12TC from The Cable Company and listening for any differences. If I hear none I'm done."
You're not starving your woofer with the 8TC's. Its easy enough to check, though. Just but the jumpers back and connect everything to just one set of binding posts.
No reason to upgrade to the 12TC. Your equipment is very good but when you start to consider cables that cost more than the equipment, it makes much more sense to upgrade active components. Don't get sucked in to the cable trap.
