Actually, it's not.

In experiments a while back I determined that there was a difference
between single and bi-wiring, but I couldn't hear a difference between
bi-wiring and bi-amping. (Which, for the benefit of the "it's all in
your mind" crowd, *implies* bi-wiring as well.)

Mind you, with the setup the original poster is describing, it may well
be a gimmick...

Actually it is!

Just do the sums. All you are doing when bi-wiring is reducing the
resistance of the 'speaker leads and increasing the capacitance. These
are already pretty low unless you're using a very weird speaker cable.
Inductance here is hardly relevant.

Similarly bi-amping whilst still using the passive crossover in the
'speakers is equally pointless. All you're doing in this case is to
reduce the amount of current taken by each power amp as each is only
driving a limited frequency range. If that really does make a difference
the power amps in question are seriously flawed. Bi-amping with
electronic crossovers makes a great deal of difference for all the
reasons APR commented.

I would very much like to see a DBT on bi-wiring or bi-amping that shows
that the difference can be heard. The sums just don't point to that
possibility.
