I run a/d/s/ and ESX right now because I know of no other 8 channel amps
with crossovers as extensive as these and a reliatively inexpensive
price
tag.

Why don't you just get 4 2 channel Kenford amps? They would sound exactly
the same.

Because I want a single amplifier to triamp my front component set, with
more power going to the midbass drivers and each channel capable of
continuously adjustable bandpass filtering. Do you know of anyone else who
makes one of these? And if so, is it 40x8? And if so, can it be gotten for
under $250 on ebay?
