[QUOTE=Carl Reid]The idea that bi-wiring effects or lack there of are due to individual speaker differences is intriguing.... Too bad I don't have any extra speakers lying around to conduct that experiment with...

As for your belief that serious speaker manufacturers must have a legitimate reason for putting the second pair of binding posts on their designs.... well.... I wouldn't be sure about that one if I was you... Dual Binding posts is practically an industry standard at this stage.... So it's not as if serious speaker companies have to justify having them... HOWEVER.... if a serious speaker company does not have them, then they have to be able to justify to the market, why the chose not to include dual posts... which will likely mean insulting and losing the business of any hardcore bi-ampers/bi-wirers/bi-curious consumers...

So rather than thinking that serious manufactures include the posts because they really believe in bi-wiring, you could just as readily conclude that they are just afraid to lose market share (which is not quite the same as trying to scam customers)...

Interstingly, I've been to several mid to high-end audio stores in the last few months auditioning speakers and was intrigued by the fact that none of them actually had their speakers bi-wired or bi-amped in their listening rooms.... Despite the fact that all the speakers (with the exception of Dynaudio) had dual binding posts...[/QUOTE

You may be right about the marketing part as maybe I'm being naive in thinking the really good speaker companies are so dedicated to their craft they wouldn't needlessly put them there for show.Still unsure on that one.I have noticed the same thing in regard to High end audio shops not having their demo speakers bi-wired.That could easily be about the extra labor and cable cost in running dedicated bi-wiring to all or most of their demos.I'm not positive but wouldn't true bi-amping create all sorts of source and connection issues with their amps,unless their mixing board was literally designed to handle that. If they're not bi-wired they can always sell you on the idea that things can only sound better not worse if you take it to the next level with bi-wiring.(even if they do or don't believe it will make a big difference)Not looking to just be contrary by the way as I figure we're just kicking this subject around a bit and that is how I've learned some neat stuff on this site.
