It would be hard to combine SET with SS I think since SS usully has more wattage than SET.
I was using ARC CA50 (45watts)on HF and Aleph 3 (30 watts) on LF. Theoretically, the HF should be 1.5 db louder, and I definitely can tell the difference. Good thing I am not a bass freak.
Anyways, in most cases, I would think horizontal bi-amping sounds better since each amp has a narrower frequency range to work with. This allows the PSU and whatever filters in the amp to perform more efficienty. In actual practice, you'd have a smoother sound and more realistic transients between HF and LF.
