@millercarbon, though I agree that extra "connections" are a potential weakness, surely you can see that some designs intended by the manufacturer to be biwired have fewer connections, not more, such as my Von Schweikerts. They are to, totally independent speakers stacked on top of each other, each with their own terminals....another situation to consider is the multiple, internal "connections' that exist in a speaker with multiple drivers....if designed to be biwired, there could be potentially fewer connections in that configuration....SO, though, we do agree that logic doesnt apply, just trust your ears.....my Von Schweikerts are biwired with a custom set of Audio Magic cables, the low end and high end using different design cables each optimized for that frequency range....sound great....
My experience with bi-wiring
Not wanting to debate the issue, which has been done ad nauseum, I just wanted to share my experience in case it's of help to anyone else in a similar position. Originally I single wired my speakers with jumpers made from my speaker cable, but I had been curious about bi-wiring and read all I could both pro and con. The main thing I gathered was that it is a contentious subject that there is no consensus on. I was reluctant to spend the money on something that may not pan out, but as the maker of my speaker recommended bi-wiring, I finally decided to give it a try. I was impressed that there was a worthy improvement in detail/clarity across the frequency spectrum. Admittedly any change is speaker dependent and YMMV, but if your speaker brand advocates it, I suggest it's worth a try.
