Bi-amping LF with high-powered pro amplifiers

Has anyone tried bi-amping the low-frequecy portion of their speakers with high powered pro-amplifiers? I am think that one may be able to get the best bass definition using pro-amp such as the Crown macro tech series with >1000W/8 ohm with >5000 damping factor (rated all the way down to 1 ohm). I know most will argue that these may not be sonically equivalent to class A or A/B amps, but what would the result be if one were to direct the power from a Crown Macro tech amp to LF portion of the speaker, and use the likes of Ayre for the mids and highs?

The real question here is, how compatible will the bass amp be with your existing amp? If you are going to biamp it is better to use the same amplifiers so you do not here a change in character at the crucial crossover point. There are some exceptions to the rule such as subwoofers with a built in amplifier connected directly to the main amp via the amplifier outputs. Using this method the subwoofer amp will take on the character of the main amp while receiving a sample signal.

I bi-amp the low frequencies with a pair of Rowland 201s and a Model 10 on top. I use a Rane equalizer as an external cross-over to shape the sound to the room. The bass is rich and deep and does not suffer from any of the anomolies of digital amps used in other applications. I firmly believe that this combination out performs any conventional amp in the same price range.

Yeap...done many a time by many a peoples.
I currently use a Crown XTi my bass drivers. The Crown has a DSP with electronic crossover, EQ, delay, etc.
500W into 4ohms.
I use a tube amp on my mid/hi drivers (320Hz and up)
