Help me choice Audioquest speaker cables

The only way to know is by trying different speaker cables in your system, in your home. That is the only way to know for sure which is best--for you. Either ask your dealer to lend you a 3-4 different AQs (or other brands/versions)--or go through The Cable Co. I just did this for power cables (for amps) and what I chose was not what I went in thinking would be best--for my ears/system. It's more work but it will be worth it in the end.

@jetter +1. The smartest way to play with cables.

The 4s11, 4s8 by canare are affordable references. 

Before you invest for an expensive cable connect a cheap cable to do the job. Usually dealer can install a standard cable for free after a big purchase. After that start auditioning some used high end cables if you think they sound better. Always buy a used high end cable, prices are dramatically less when you buy them used. If it doesn’t make a significant difference, try another one at another price range. Have playlist with detailed jazz songs, try same list on two different cables.

"drbay" great advise, I will ask the Dealer to supply both the 10ft demo cable and any others they have. Thx

I have B&W 800d3 also but with AQ Wildwood speaker cables, very similar to the Redwoods.  I’m pretty sure you will like the Redwoods.
