Biwiring make any sense?

20+ years ago I had Paradigm Studio 60's and 4 Marantz MA500 mono blocks, with bi-wiring. 

The dynamic range seemed better, the bass slam also a little better.

My take away is the same gains can be achieved by putting the money for the extra speaker wires into some other part of your system.

Here is A video from Paul that might shed some light on your question

No.

Paul McGowan up above goes into detail on the matter, says it doesn't matter with regard to biamping, then  recommends biwiring!  Holy smoke!  I knew he liked wires.  Meanwhile, the rather overworked video referenced on Matthew's post up above really does a good job showing that biwiring is nonsense from an electrical standpoint.  I have to admit I am skeptical about those thin metal jumper straps often supplied.  The KEF's I'm looking at has that internal so you would have to guess that's real wiring.  Don't know about the PSAudio speaker.  I would like to hear some thoughts on those 2 speakers I was looking at before I release the $$$. As far as the biwiring goes, I think if you have the cabling already (I do), at least it wouldn't hurt.  If you don't I would spend the money elsewhere, maybe starting with better jumpers.  Thanks for the comments!

What about biwiring with  silver  for High frequencies  and  copper  for low frequencies ?
