I bought a bunch more of the WE10ga before I left to ride my bike across Iowa.
I biwire my speakers with a pair of 10 awg wires on top and a second pair on the bottom and I have considered trying star quad runs for 7 awg to top and bottom, but haven't gotten around to it yet.
As speaker cables, I think they sound great with a perfectly natural distribution of frequencies, if maybe a little mid-oriented. Bass is full, textured, and has impact when it is on the recording. Highs are smooth and natural IMO, but may not have enough emphasis for some.
I am running huge current into power hungry speakers so ymmv. I use spades soldered to my cables but would not argue with those who recommend no connectors. I like soldering the tinned wire for a more direct connection with the copper below the tin coating.
This wire is also perfect for power cables. I use a star quad configuration for 7 awg to my two 300wpc Class A monoblocks. A single twisted pair is just fine for front-end components and preamps. This is the same wire TWL and Mojo Audio used in their highly regarded power cords of a few years ago.
