When biamping, the two amplifiers serve totally different types of drivers. Why then would the relatively subtle differences between two decent amplifiers be important, as some people say in favor of the vertical configuration?
As a serial biamper, let me say that I have configured systems for two reasons... (1)...To put the more powerful amplifier where power is needed...(2)....To put the better quality (low distortion) amplifier in the HI slot where distortion would be most noticable.
Each driver in your speaker system is optimized for a particular frequency range. Ideally the different amplifiers would also be optimized according to their application.
