Bi wire, bi speaker/amp

Anyone?

I would opt for two pair of Audioquest cables. Something like a GO-4 or Rocket 88, which aren't to expensive-even new. 
Just connect both sets to the amp(piggybacked) and run one set to one pair of speaker terminals and the other to the 2nd set.
You should notice a subtle difference in sound output quality at the very least.

I am curious about Bi-amping, and this may be a silly question. The amplifiers to be used should have their own volume control? Most of the stereo amps I have looked at do not have this unless they are an Intergrated amplifier. I thought the set up would be one preamp feeding two amps with each dedicated to either the high or or the lows. How does one influence either amp if both are controlled by the pre? 

Or or should it be two Intergrated amps?

That's one reason to use an active crossover.

@pack,
There are two ways to bi-amp. Horizontal and Vertical.
The former is uses two amps with each controlling one channel.
The second uses one amp for the higher frequencies and one for the lower.-I believe this is what you are asking about.
FWIW, I find this set up to be more problematic than beneficial, but I am sure others will disagree.
In any case, the preamp will provide the signal to each amp, that amp will relay the signal to the speaker. If you use the same amp for both high and low, there should not be a marked degree differing sound quality. But, if you use two different amps, you (theoretically) can influence sound reproduction.
As I mentioned, it can result in a new set of problems, but for some, it can offer positive results.
