Has biwire speaker cabling become "old" ?

So, is this lack biwire availability a cost cutter or a result of evidence that biwire (and bi-terminal speakers) is ineffective, that it was/is a cosmetic trend only ?

No real answer, but a lot of opinions. IMHO, the best answer and I quote well respected poster, Almarg,

"It may or may not make a difference. If it makes a difference, it may or may not be for the better."

Some manufacturers specifically design their speakers to be biwired, and others have just added the connections as a means of "audio fashion".

IME, I achieved better results with single wire and jumpers as opposed to biwire, and as I was trying the options, I found this article that seem to describe the difference I was hearing.

BI-WIRE, NOT ONLY AN ADVANTAGE

Bottom line is you try different configurations, and go with what you like.
