IMHO, speaker wire is less likey to change character between brands and makes than equivalent line level interconnects. In my system(s) (past and present) I *could* hear differences between some interconnects using *similar* construction. Once you get past a certain "threshold", it gets exponentially hard to discertain, or something. :-) For far more of the solid core copper speaker wires with spade lugs - all sound the same to me. So I just bought a used pair pair of tara labs space and time the looks good and has quality contruction and leave it at that. :-)
But I can tell you one thing, it *did* sound less veiled than 8AWG stranded monster speaker wire with bananas. But I don't think I could tell the difference when say AudioQuest and Tara Labs, if both used similar construction and materials. Heck if they were made well enough, they could probably be a little dissimilar, and I doubt I could assertain which was which! LOL! ;-)
I'd say if you can't tell the difference between interconnects, I *doubt* you'd be able to discern between speaker wires. YMMV.
