The key is to have the EXACT same amps, cables, cable length, terminations, on all parts of the biamp setup otherwise you risk temporal and of course sonic inconsistencies from different drivers. Throw in exact same power cords and exact same interconnects too.

Ycables are not advised unless they are full and exact mirrors of the interconnect; no coming in with 8 conductors from the source and splitting to 4 conductors after the Y. If that is the only choice, use a preamp with dual outputs and run 2 full pairs to the amps.

Biamping is not always better, it also varies with the speaker in question regardless how you drive it.
