I've been thinking to myself whether it's really worth it or not to purchase additional hardware just to "bi-wire" speakers. Most capable B&W's come with the brass or gold jumper if you only have one set of cables going to the speakers. What is the difference between having the jumper in place vs. one cable per binding post if it's all coming from the same amplified channel on your AVR? My Pio 1014 has the ability to bi-AMP but what is the big deal of "bi-wiring" if the supplied power is coming from the same single channel? Isn't this exactly the same thing as leaving the jumper in place between the two pairs of posts? If anyone out there can shed some light on this I would really appreciate it! TIA!
