I have multi-elements that I can and do use separately and together. I'm happy with all my amplification gear. I can handle 25-500 people easily.
* Mackie 808S stereo powered mixer
* Mackie 300i 12" two-way passive speakers
* Soundtech 12" passive wedge monitors
* EV Sb120a 12", 300w sub-woofer
* Kustom KMA-100 15" 3-channel keyboard amp/PA
* Roland CM-30 6" Cube monitors (2)
The Mackie setup is clean, clear and powerful. I'm usually running a monitor channel, so the Soundtechs have been doing that job for about three years now. The EV sub is fantastic and I'm starting to use it more and more often with gigs of any size. The bottom it adds to the Mackies is sweet. The CM-30's have seen sparse use, but they too provide a nice clear sound in close quarters with smaller groups. The Kustom is a decent 15", 100watt amp with DFX; very compact, easier to cart around than any large keyboard amp I've owned - and I've had a few.
I too would like to try the Bose PAS but am just not playing often enough any more to justify such a purchase. I've spent the better part of a year re-configuring my keyboard setup. Hopefully that's done and maybe I'll start re-evaluating the amplification situation.
or maybe I won't
