Biwiring - a non-subject that will not gain you any sonic advantage
I really wish this subject of biwiring would just disappear up its own terminals. I don't have many ambitions in life but killing this discussion by deleting the biwire terminals and reverting to just one input pair is going to be at the top of my 2011 New Year's Resolution list for the remaining models that still feature biwire legacy terminals! You've given me a real motivational boost!
The terminals were fitted for one reason and one reason only: to give the user choice. Have I ever used them at exhibitions? No. Have I ever used them for critical listening? No. Have I ever used them during the design of the speaker? No. When we were offering the biwire terminals, right at the end of the design process (which has all been with single wire) I took a saw to the prototype PCB, cut in in half to isolate the bass and tweeter sections and then made a pretty PCB layout based on that. Did I listen to the biwired crossover before authorising production? No. Do I believe that even 0.00000001% of enhanced performance can be gained? No.
Of all the subjects ranged over in the speaker arena, this one is a complete and utter waste of time - in my opinion. But what do I know about it? I only design the speakers ....... !
Biwiring does do one thing very well though: it introduces the one and only, much appreciated 'fiddle factor' to allow individuals a physical and psychological interaction with their speakers. What else can you do to them other than dust and polish them?
