Help me choice Audioquest speaker cables


What Audioquest speaker cables should I choice to hook up MAC C611 amps to B&W 800d3 speakers? Will be using MAC C2700 tube preamp. My dealer suggested I USE REDWOOD cables. 

128x128farne230

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. 

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.

My experience, many AQ models over many years:

  • Silver is better - usually gives a good bit more detail without getting too bright. But the "bigger" silver models are usually better, as the entry level models can often be a little lean / lightweight and sterile by comparison. 
  • Silver is worth it when you're searching for good deals on USED cables. However it's hard to justify their current "new" silver prices. In that case I'd say copper is more than good enough; use the saved money for other upgrades. 
  • I found the best improvement from Hurricane PC's is on power amps. But I still really like the old NRG-1000 cords. I'm also quite happy with NRG-1000 type cords on all my source and preamp equipment.
  • Speaker cables are #1 importance, then PC's on amps (and maybe Niagara) #2, then ICs and source PC's #3. 
  • There are often great used deals on older AQ models but the lines are VERY confusing at first and you have to watch out for counterfeits - especially on certain models: Sky, K2, WEL Signature anything. And all the new stuff :( 

It appears AQ has not mailed the cables to my local audio shop, so in the interim I have created a list of possibilities using AQ cables without auditioning.

Speaker cables (3Ft-3.5Ft): WIlliam Tell (silver) combo, Thunderbird Bi-combo, Firebird Bi-combo.

Interconnects: 3-sets of Black Beauty XLR (1m).

Thunder AC plug (1x) for Niagara 5000.

Not cheep but would like your opinions especially if you have auditioned these cables. 

Thx
