Audioquest speaker cables

So they use a different AWG with the bi-wire option?  The William Tell zero is 13 awg.

Yes. Both @ctsooner ​​​​@gdnrbob have the better AQ after hearing both. 

15’ is a significant performance hit, no matter the cable - i am sure you are aware.

Yes the AQ can and should be two sets of cables, so no concern about awg.

hope this helps, enjoy the journey and the music. Rutan at @audioconnection can demo both.

I  use AQ power cords and a Niagara 1200. I like what it does for my system. I have not used their speaker cables or interconnects. Have you considered triode wire labs products?

I looked at your system, i think the copper might sound better w brick fireplace and the B and W tweeter. Save some significant $ You could also try single cable w jumper to ease in cost wise, then add 2nd run later.

Yes, I believe the bi-wire is copper.  Yeah. I go back abd forth between getting the wires separate to save money upfront or biting the bullet and getting it all at once.
