Has biwire speaker cabling become "old" ?

Sorry, I was out of line....I apologize.  Sometimes I think common sense and experimentation can yield verifiable results without relying to heavily on any one mans gospel.  RV is a good egg however, just need to balance sage advice with actual trial and error sometimes to determine if what does it for the adviser delivers for the advisee!

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!!
