Possibly dumb question: can I use two cable runs for each channel, not bi-wired?

I'm moving my components into another room, in order to shorten the existing 30 foot cable runs to about 10 feet,
and will run the cable through the wall between adjoining rooms. I'm wondering if I can make use of the resulting "left-over" lengths of cable by doubling up each run, utilizing one pair of binding posts for each side. Has anyone tried this? Question #2: should the pairs be jointly terminated,or should I use bananas coupled with spades, so that there are 4 terminations at each post? I haven't sen any references to this in the past, so it may well be in violation of some basic rule of physics, but I thought I'd ask, anyway.

As far as being able to do it, I would say yes. This would be a true Bi-wire set up, but in your case, you would be doubling the cable to the same post. Would there be a sonic difference? Probably. How different depends on your equipment.
As far as terminations, I have heard many opinions. Some prefer Bare Wire as the most the most revealing. Though the banana/spade combo should work well.

Yes. Until I found the best single cable for my system, I had it bi-wired using two different makes to achieve the best sound. I just made sure to use bananas for one run and spades for the other. Or, you can use bare wire and spades, or bare wire and bananas, but I wouldn't try both with spades. I don't think you'd get a good enough grip that way.

In the end, it tended to be a bit "phasey", for lack of a better word, but it sounded nice.

All the best,

sure you can, but the question I have is why?

If you double the wire as you have suggested then the result electrically is that is you halve the impedance of the cable. This may tighten the bass response since the impedance of the cable is halved.
Try it, and use your own judgement.
