Actually, what would actually be helpful is if someone would buy a series of increasingly expensive jumpers, take good notes on the performance of each, and report back. That is instead of assertions with little or no experience, based on nothing.
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?
