Tannoy supplies jumpers for their higher tier speakers in the event you don't bi wire...last time I checked, Tannoy does not make speaker cables...so, I doubt it is necessary to use the exact same wire as used for the main run of speaker cable. If this is good enough for Tannoy, then it's good enough for me...I'll use their jumpers...although right now, I bi wire with two equal runs of Audioquest Type 4....
HOW CRITICAL ARE JUMPER CABLES
When using jumper cables instead of biwire speaker cables, do the jumpers need to be as good a quality or better than the actual quality of the speaker wires? The jumpers need to be 6” to 9” long. Also is it better to hook the main speaker wires to the low end and then run the jumpers to the high end or visa versa?
