Bi-amping can bring substantial benefits, especially when using an active crossover between the pre-outs and the power amps. The gains with passive bi-amping can be very worthwhile in many circumstances.
I have never seriously believed in bi-wiring. However, when re-organising my HT setup a few weeks ago, I took the opportunity to install two runs of wire to my my fronts.
Listening to the bi-wired output, it seemed better! I thought I must have been wrong about bi-wiring, even though it is illogical that it could seem to sound so different.
I determined to find out if what I thought I was hearing was correct, so I put in a switch system which would re-instate the connections between the two sets of terminals on the speakers, thus negating the bi-wire.
When I tested the system without knowing which setting it was on, I found that I couldn't tell the difference. All psychological/psycho-acoustic.
At this point, you may be assuming that I'm partially deaf.
However, I get better than average scores on such things as
PCABX tests .
Even if you can get great scores on some of those tests, it's probably still not worthwhile bi-wiring rear speakers!
