Is true-biamping now cheaper and easer?

Crown now, in their XLS series, sells high powered stereo amps (300 -500 per channel/8 ohms, doubling into 4) that offer a highly variable low and high pass filtration that can be channeled selectively into the left and right outputs. Moreover, the gain of each output is individually variable. Hence, two-way, bi-amping is now easy (you select the cross-over point, and adjust the volumes of the tweet and woofer) and cheap, ~$300-500 per speaker. Just get rid of that awful passive crossover.

Is this a great possibility, or am I missing something.

P.S.In responding to this, please realized that I don't believe that one can hear either cables or amps (given they have the watts). I prefer objectivity, something one hear it 'blinded'!
