Rodman99999: "Both amps will still remain saddled with reproducing the full signal, from your preamp."
Well...yes and no. Certainly each amp is driven by the full-band signal from the preamp, but each amp doesn't drive the same full-range signal from the preamp. This is because each amp is driving only part of the speaker's crossover. The amp driving a low-frequency end is presented with a load that increases its resistance dramatically as the frequency rises, and each amp driving a high-frequency end is presented with a load that increases its resistance dramatically as the frequency lowers.
Then if one has an amp with great-sounding bass and edgy treble, use it as a bass-end amp, and if one has an amp with great-sounding MR and treble but is a bit wimpy in the bass, use it as a upper-frequency amp.
Of course, the biggest problem with passive biamping with different amps, that of matching the different Voltage gains, still remains if one doesn't already have gain controls on the higher-gain amp.
IMO passive biamping can be rewarding, but it's not for novices unless you don't care if the tonal balance of your speaker systems ends up badly inaccurate.
