Has biwire speaker cabling become "old" ?


I notice some makers are not stocking biwire termination. Has biwire gone out of favor ? Was it sonically meaningless ?
Have speaker makers dropped it ? Do us owners of biwire built speakers need to resort to jumpers or aftermarket biwire cables now ?

more expensive cable price, doesn't necessarily mean better performance.  You must hear the cable in your own system to know if it helps.  If it does...bi-wire if your speakers are designed for it.  Use seperate cables for the top and bottom... The cables that have 2 spades on one end and 4 on the other are far less effective.  Keep the cables seperated
MIT delivers otherworldly musical vistas for me...all else is just wire.  There are patents involved!
Biwiring is BS!   Most of the time, no audible improvement IMO.

Been there, tried it.
My Krells have crossover boards for each section and my MIT M1.5 Biwires have dedicated networks for high and low pass signals...BIG DIFFERENCE!!
First off we should all listen before buying.  I was all bout MIT when I had my Quicksilver/Proac system.  It was years. I'm actually shipping my 330 shotgun CVT cables out tomorrow as I finally decided to sell them.  Bruce B actually rewired my preamp with his internal wire many years ago.  He among others make some great cables.  No doubt, but I liked the AQ cables much better with my Vandersteen/Ayre system.  I did listen to bi wire vs single vs the bi wire within ONE cable.  I wasn't able to afford the second set of Castle Rock to do a true bi wire, but I'm about to pull that trigger. I noticed a nice difference, however I also feel that upgrading components usually makes a bigger difference than upgrading cables (dollar per dollar).  For those who make a claim that bi wiring is BS, you have no credibility.  For you it obviously didn't work, but some systems are designed to be bi wired and it does make a nice difference.  

Dave, it's all good.  I do listen to Richard a lot.  He makes a ton of sense and I trust him.  That said, I have my own ears.  He and I seem to like similar sounds.  It wasn't like that years ago and I didn't want Vandersteens.  I listen differently now than I used to.  I have heard differences for years IRT bi wiring.  I have heard lesser cables with a true double run sound much better than a 5k single wiring with jumpers.  That's just me, but I'm sure a ton don't hear a difference.
