mono block or bi-amps which would you pick?

2 mono amps
 -  being close to the speakers you significantly shorten the distance traveled over speaker wire resulting in less entry points for distortions....AND....
 - since the length is shorter, you can opt for better-sounding speaker wires that may cost more than you'd otherwise be able to afford for long runs from the amp.

I went from stereo to monoblocks and never looked back so, mono it is.

Another vote for monoblocks. I will never go back to stereo again.

If there are mono amps of which you can afford four, you can bi-amp with mono blocks. But not all speakers benefit from bi-amping, which has more to do with the speaker's crossover than the amps. And not all speakers CAN be bi-amped. Many bi-ampers like to use a tube amp for the midrange and high-frequency driver(s), and solid state for the woofer(s), while others like to use identical amps. Do you plan to use an outboard electronic x/o? Bi-amping is more involved than just using two stereo power amps.

i just bought a German made horn speakers call Odeon Accoustic no#30 ultimate.   They are 93db 8ohms 3 way configuration ( serparate enclosure for each drivers.   The tweeter are compression drivers say 1.75 inches, the mid are 5.75 inches and the bass are 12inches.   Each of the drivers has it own enclosure separately with passive crossover built in.   Here is my dilemma:  is it better for me to run mono amps ( 100-250watts per side)  or i should buy two stereo ( 100watt bass ) & (100watt midrange/tweeter)  run it bi amp.   Price is no object; what would be the optimal that i can utilize my money, my resource to get maximum performance??  Please give me your advise??
