I agree about Wiring to the tweeter and Jumpers to the base. I also feel they make a difference. When I added AZ jumpers to my Hologram single wire cable, there was a clear improvement. Please also remember a clear advantage of single wire, when you change speakers. It seems more manufacturers are going back to Single pair terminals. What do you do with your expensive Bi Wires then. Just the situation when I changed to single pair terminal Acoustic Zen Adagios.
