I recently had a conversation with a dealer regarding speaker wire. I wanted to make an upgrade and asked him what he had in my price range. My speakers are bi-wired now, and I wanted to keep them that way. He suggested that I get one pair of speaker cables of a higher quality vs. two lesser quality pairs. He also said that a lot of times a speaker will actually sound better with one pair vs. a bi-wire hook-up, as there is less interaction between the two pairs. Will I thought I'd try for myself with the cables I had, to see which sounded best. First I did some listening to familiar tracks with my current bi-wire set up, then removed one pair of cables and added jumpers. Well it wasn't a huge difference, but the single run sounded a little more coherent, and focused. I then took it one step further, and connected the hook-up wire coming off the crossover to one set of binding posts, now I didn't need jumpers. The improvement was such, that I had a hard time believing it. Things were not only sounding a lot more coherent and focused, but much smoother with greater detail and presents. Has anyone less found that a single run sounded better than a bi-wire arrangement. If I remember correctly, there are a few speaker manufactures such as Thiel, that do not believe in bi-wiring.
