Monoblocks, passive bi-amped or passive tri-amped?

I have been doing lots of research, but to no avail. Some writers & speaker builders say you will get sonic benefits from passive bi or tri amping, some say you get nothing. Some say running 2 identical amps will give a 50% increase in power to the speaker…some say zero. IMO it seems logical that an amp pushing 1 driver, as opposed to many, would have an easier load, and thus more headroom, control, speed, detail, etc.

The options I’m considering:
250W D monoblocks
220W D bi-amped
140W A/B tri-amped

I can’t active amp…so need technical info on which of these would sound best, and why. Thanks!

Isn't most of the power demanded by the woofer? So, adding a second amp for the mids and high doesn't really take much load away from the woofer amp.(assuming a three way design) I agree that adding a second identical amp does not really double the usable power available to the speaker. The tweeter amp mostly goes to waste.

What does "passive" mean? To me, passive indicates something that is not powered. Do you mean you are not using an active x-over and letting the amps get all the signal?
