Two Stereo Amps, Bi-amp or Monoblock?

From what I have seen, the normal step-up from a bridgeable stereo amp is to buy another and use them in monoblock format. You could however buy another and leave them in stereo and simply use one amp for both channel tweeters and one amp for both channel woofer/midrange. I understand that this is not a full 4 monoblock bi-amp configuration, but I wonder if the bi-amp advantage is glimpsed to a large extent in this format and perhaps a better sonic improvement over running the two amps in monoblock. Thoughts or experiences? Aside from sonic benefits of either, what is the resulting power increase from the two formats? In the "bi-amp" format you would also have the ability (or advantage) to offer a different amp to the tweeters and to the woofer/midrange; whereas in the monoblock you would need to match the amps.

Thanks for the response. I sent this question to Steve Deckert of Decware (zen amp) and he replied:

"The pros of use as monoblocks is 3dB more power before clipping, and better separation. Also the ability to place each amp close to the speaker so you can use less speaker wire.

The pros of biamping is the ability to adjust the volume of the tweeters and woofers separately. Also allows you to voice each amp to more ideally compliment the signature of each driver."

I'm gathering that biamping with stereo (2 total amps) does not increase the power while biamping with mono (4 total amps) would.

Anybody have experience running Zen amps on De Capos in any of these configurations? I guess I'm concerned about the medium efficiency (92db) for a 2A3
