to bi-wire or not?

Richard Vandersteen is a proponent for bi-wiring, but as akg points out, it is speaker dependent.
But, if the speaker manufacturer made the speakers bi-wire-able, then they probably should be.
I think your dealer should be able to provide a loaner pair for you to try, too.

To OP, does Joseph Audio recommend biwiring?  As gdnrbob said above, get loaners from your dealer and check it out for yourself.

Vandersteen crossover designs are optimized for true biwiring and I have, in 30 years of Vandersteen's, never run them any other way.

@vinylbliss I own Joseph Audio speakers and I kind of "bi-wire" them. Before I did so I asked Jeff Joseph if he recommended it. He said he didn't think it made much of a difference. I like the effect, but the way I'm approaching it is not transcendent by any means. I only did it because for not much more money I could get the end of my speaker wires to be quad wires on the speaker end (allowing one pair low and one pair high attachment) and single wires to the positive and negative poles on the amplifier. I don't consider this a true bi-wire, which as others note is two separate cables independently from the speaker to the amplifier.  

 I’ve talked this over with several local dealers who I respect and got  diametrically opposed opinions on this issue.   But the folks at Acoustic Zen and Used Cable  are big supporters of “true“ bi-wiring (by that they mean using two cables to each speaker).    Based on that I took the plunge and purchased a pair of “shotgun” bi-wire Acoustic Zen Satori cables.    As I have used these cables before in “mono” format I will report back my impressions of the difference.

 Thanks to all for their input.

I recently did a test with my system and could hear a difference in the sound quality when I bi wired.  It helped to separate instruments better in some recordings and the sound stage was a bit better.  I think it all depends upon the gear you have as to whether or not you'll hear any benefit.
