Help me choice Audioquest speaker cables

I ordered the MAC MC611 monoblock amps and C12000 (12000c & 12000st) two box preamp and already own 800d3 Speakers. I will work towards purchase of equipment than set down for cable selection. But I have time to research opionions in the mean time. .

Your dealer offering demo Redwood for $6k is far closer to a kick in the teeth than a favor. That model has been discontinued for at least a couple years, and is now highly depreciated on the used markets. The model above it, Wildwood (also long discontinued), is significantly better in ever way (twice the silver content, much better sound) and 6K is still way too much even for THAT model. 8ft Wildwood have gone used as low as low 2K recently. Dealer seems like he wants to offload old stuff on you for premium prices. 

Mulveling, seams so..

Thx

Five months later and I finally finished gathering my equipment, as mentioned above: Speaker-B&W 800D3, McIntosh MC611 pair, Mcintosh ref. preamp 12000C/ST, McIntosh MEN220 room conditioner, AudioQuest Niagara 5,000 AC conditioner, HIFI Rose 150B streamer, setting on Solid Steel Hyperspike series stands. Cable lengths for equipment and speakers 1m. My dealer has agreed to provide a few of AQ speaker cables and IC to try with this system. We may do this before we add 4x Auralex 2"x4'x2' panels behind the listening couch since our room ceilings are high and the room echo's. It has been a full year in preparation and affording the expense. Now to chose cables. Any general suggestions on Silver vs Copper, which cable placements will most likely make a difference as well as if I should replace the AC cables on any of the equipment (of course the Niagara  does not come with a power cable. Thats everything so far.
