To me Vertical biamping would imply one amp for the lower (BOTTOM) freqs and another for the upper (TOP) freqs. But this is unfortunately NOT the "definition". It is not about amplifier tiering. Vertical here means one amp drives one entire speaker (top-to-bottom) frequencies and the other amp the other speaker. It is such a confusing terminology that I wish were never "invented".
This configuration has the advantage of greatest channel separation. The downfall is that both amps have to be exactly matched and they have to handle the entire band which eliminates the optimization of finding amps that work so very well for one band or the other.
In any configuration, I feel that biamping only benefits the system greatly when you have optimized the speakers about as good as you can with one amp - you have reached that limit. Putting 2 mediocre amps and a mediocre active crossover (if this is used instead of the passive crossover in the speakers), and the extra cables, etc., will only result in not as good a sound as you already have.
