Further reading revealed Bi-Wiring and Bi-Amplifier. Yamaha's A-S700 instructions are for Bi-Wiring which does nothing. Bi-Amplifier is not all that effective unless you do the crossover before the amplifier instead of at the speakers. Now that does something as it limits the frequencies in each amplifier, reducing harmonic distortion and keeping heavy base out of the tweeter/mid-range channel. That can help!
But for Yamaha to promote a meaningless Bi-Wiring scheme is wrong when they obviously know it does nothing for sound quality. That was my point.
In a slightly different vein is the use of expensive speaker wiring of hugh gage wiring. Unless your speaker wire runs are long, it is a waste of money, in my opinion. If my amp is putting out 120 watts (which would be impossible to stand near in any normal sized home) the actual current in the wire would be about 2 amps. Any 16 gage wire (like you get in good zip cord) can easily handle that with minimal line loss.
