I have VR4 GenIII's & there is a 3' distance between the upper & lower module binding posts. I bi-wire these, as a 3' jumper doesn't seem practical to me from an economic standpoint vs. another set of cables. I did try using some inexpensive "jumpers" while auditioning different speaker cables & there was a difference in the quality of the sound, but to be perfectly honest, don't know what if any difference there would have been (compared to bi-wire) if I had used the same quality of jumper, as it was economically impractical to do that just for auditioning purposes.
Some 'philes who bi-wire use different brands or materials to further experiment; for example, copper for the bass & silver for the higher freqs. Additionally, a full size set of cables can be more readily sold if the user wants to try something else, etc.
As for bi-amping, using an electronic crossover is the best way to utilize multiple amps, as I have heard the same speakers with an electronic crossover then passive crossover & there WAS a very major difference between them. Most home stereo systems don't have electronic crossovers, so the bi-amp question, once you decide whether to use vertical or horizontal bi-amping, is if it makes enough of a difference (it will, regardless of configuration) for you to warrant the additional expense. Also, there is the question of using stereo vs. monoblock amps.
You'll have to experiment & judge for yourself and then decide if itÂ’s within your scope of diminishing returns
