John, I understand what you are saying as far as what Darren is inquiring about. But as far as bi-wiring being "useless" I find a very substancial difference with my 60s bi-wired. On the Sunfire amp, there is a seperate voltage, and current source, on the 2 channel amp. they are obviously both current and voltage, but the voltage (high power) to the lower sections/woofers, and current to the higher mids/tweeter offer the best of both. This is more "vertical" bi-wiring, and there are great audible benefits. Taking it to another degree, some run a high power solid state amp to DRIVE the bass end, and a "warmer" tube amp - or "tube like" amp to run the mids and highs. The vocals are VERY much enhanced. Bi-wiring (can) bring the 60s to a whole different level.
