High end speakers without bi-wiring?

I think a lot of this has to do with just being concerned about good speaker wires. Someone who is going to bi-wire their speakers is spending extra. Usually bi-wire should be and is lower gauge or thicker before they terminate. This heavier wire should provide better sound. The jumpers provided by the speaker company can be fairly thin. Not good. The jumpers don't provide the continuity that you would want if you purchased expensive speaker wires. Spend a grand on speaker wires that end up going through a ten buck jumper?

I do not bi-wire, but side-step the issue with those kinds of speakers I own by passing a single wire through both terminals to bridge. Hate the jumpers thing.

Alan Yun of Silverline told me his (or my) Preludes were more "coherent" when single wired. He also warned me not to lose the jumpers as they were costly. Of course I biwired them initially (after all, what does HE know?), and after listening for a couple of weeks (and since I hadn't lost the jumpers yet) I went back to single wired. The result was my learning the definition of "coherent", as he was 100% correct. With these speakers anyway...also, I have no desire to replace the little gold plated solid jumpers as I firmly believe they are the optimum connection between the posts. Any other options like using the same wire as the speaker IC, or spending big bucks on a two inch "jumper", seem VERY silly.

Thanks for all responses.
It's been a while, but I had tried Clear Day Shotgun cables, both biwire and single wire with double core. Price was the same. I could not quite notice the difference between the two. However, both cables were better than other cables that I had.
The maker of the Clear Day cables suggested to use double core shotgun (single wire), and that is what I use now. I've wondered since then whether biwire was the result of another voodoo science or not. Looks like there is no consensus on this subject, like many other areas in this hobby.
