Need a good biwire cable pair for b&w 802 d3 speakers?

Bad choice, no difference. 
1. McIntosh have an output transformer and low DF (40 or less). so speaker cables do not make a difference.
2. If you look at a Bi-wire or an equivalent full range cable, that has the same cross section, the  full range cable will perform better.
It show up on P-Spice analysis. It also makes sense when you think of how currents flow there.
Bi-Wire was a big sales point in the mid 90's. Forget about it. 

I found AQ to be good with the 802d3 I have. 
Had Oaks and also have Wels.

you raise some really good points. Can you clarify pt 1.

for those who believe in cables, what about ‘transparent’ cables.  Seems to be a really good Maine co that offers strong expertise.

$80 speaker cables for those 802 D3?? It does not make any sense. And if you are looking at that price "range", really, does not make any difference. Buy from Amazon or Home Depot
