I have been reading about this as an audiophile who would have been skeptical initially. I recently sold my ATC SCM40's and stepped down to the Bowers & Wilkins CM5 due to the design of my living room. I never bothered trying this with the ATC as it was tri-wireable and that is just silly based on the rest of my kit. After reading a document from B&W on the subject, I connected the CM5 to my Yamaha A-S2000 with my old Audioquest Type-4 and my more recent GO-4 and I was amazed at the difference it made. The vocal centering was razor sharp and the soundstage was somewhat expanded. All of this time I had assumed that the bookcase behind one of my speakers was throwing the image off. I have actually ordered another run of GO-4. I know that $1300 worth of cable on a $1500 speaker is strange but there might be 802's or 805's in my future.
bi wire or not to bi wire
I only have 1 set of biwire cables and 1 set of non bi wire cables so I cant do extensive listening tests. But to o my ears my Usher speakers loose of bit of bass when I bi wire, but thats about it. What are the other potential advantages or disadvantages to bi wiring? Thanks.
