Bi-amping without using electronic crossovers is pointless. As Guido said
above, there's no point in it, and the results will almost always be
worse,
never better. If you want to play around with the treble/bass balance of
your 'speakers, then fine, enjoy yourself by all means, but don't expect
the
results to be better than what Martin Logan originally supplied. My advice
is to use the Bryston amp as this is one of the better engineered units,
and
keep the ARC for nostalgia, or indeed, sell it and use the money more
effectively.
