Has biwire speaker cabling become "old" ?

Is it possible, however unlikely, they put 2 sets of terminals on the speakers for something other than marketing purposes? Maybe he didn't believe in biwiring, but he did believe in biamping.

Pure speculation on my part.
I recently read a review of a Vienna Acoustics speaker where the author mentioned how pressure was put on the manufacturer to ad an extra set of binding posts for biwiring. The pressure was coming from the American importer because in his opinion American audiophiles demanded biwiring.

I was very upset when I realized my speakers were tri-wired...

Curious if the pressuring importer also sold cables...

This is obviously a topic many people have questions about (myself included) based on the number and variety of responses. I recently recabled my Avantgard Trio horn speakers changing from the manufacture recommended biwire cable to a single high quality cable and then running a jumper to the powered subs. The result was much better sound which I attribute solely to the higher quality cable, not the configuration. I suppose if one could compare the biwire arrangement with the same cable used for the single run, the experiment would be complete. But that would have been outside my budget, essentially doubling my cost. Bottom line, in this case the single run cable array was the better option.

Silverline Audio recommends biwiring for all their speakers in their somewhat generic setup suggestions. When I found a used pair of Preludes years ago I found that one driver wasn't working so I called Silverline to see about a replacement (it was a wiring issue so I ended up not needing one) and Alan Yun (the owner/designer) answers the phone...a fun conversation ensued where he tells me the Preludes specifically should NOT be biwired as they're more "coherent" single wired. I tried both ways, and he was right...my conclusion is that it is taste and/or speaker specific, and nothing should be assumed without listening closely.
