to bi-wire or not?

@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.

PS.  I use two separate cables for each speaker.

This thread got me interested in trying bi-wiring yet again.  I'd tried it in the past but didn't think there was much benefit if any at the time (different system components than now; different wire).  Tried it this weekend running Cardas Parsec cable to lower posts and Clear Day double shotgun wire to upper posts of Prelude Plus speakers.  (I know -   some experts say not to use different cable types.  We appreciate expert opinions.)  Amp is a Hegel H200 (two pairs of outputs for each channel) in HT by-pass mode using a Freya pre amp in JFET buffer mode.  This time around, I did think bi-wiring made a difference; very similar to the comments of @will62 - more air, detail, a bit more separation for instruments and voices, and better imaging (more stable, better defined, more 3D).  I'm not saying it was a huge night and day difference but improved enough such that music sounded "better".  Didn't hear anything that could be considered a downside.  If interested,  rather than agonize over theory, it's worth experimenting and trusting your own ears.
