xsparky,
Opinions vary on the audibility of speaker cable differences. I am talking about cables without trick networks or other electronic filters to tweak the sound. As far as the latter go, you are far better off with an equalizer. I do not hear differences among non-trick cables of adequate wire gauge.
As to Bryston speaker cables, I had a pair and was very happy with them. Recently I changed them for another similarly priced brand with a black covering, because I needed longer cables and I wanted them to vanish on the dark wood floor. I can't tell the difference, audibly.
By the way, I am not deaf! I hear plenty of differences among speakers, even among many electronics, and especially acoustic differences among rooms. For years, I played the flute in school bands and orchestras, and I'm an avid music fan. I just say that because it might put it more in perspective when I downplay cable differences.
I think the Bryston cables are fine products.
I wouldn't bother with biwiring. Any audible change is sure to be less than moving your listening position by twelve inches. Why not spend the dough on more music?
Have fun!
