I'm a novice at this whole Home Theater setup stuff, but I recently upgraded from a Sony DAV-HDX265 HTIB system, and since the speakers had proprietary connectors, I had to rewire them to my new Pioneer VSX-819H. I bought this wire because it was cheap.
Never having spliced before, I used a pair of scissors and a box cutter. I had enough wire to do 5.1 surround in my small, living room. I just ran the wire along the room's moulding, since I have no idea how to do a proper wiring job. Therefore, I dislike the ugly, bronze wire insulation since it's completely visible.
In any case, the sound is fine. I was nervous that my Sony HTIB speakers wouldn't work, but they do, and probably sound a bit clearer. In the near future, I hope to: a) use the leftover wire to set up my Polk Audio PSW10 subwoofer according to Option #2, and b) to pick up a set of Polk Audio RM6750 satellites to replace my HTIB speakers.
Never had a problem with Dynex; would recommend this product to a friend.
