Well, my recent upgrade cycle is over (for now) and the rig pictured below is what I'm using. I just stacked everything together for a pic, I don't really run it with a cab on top of the amp, BTW. Lots of options. For a small room, the Bergie's are good by themselves, either/or. Slightly larger rooms call for the Epi into one channel of the Stewart (or mono-bridged if I feel like it). My priorities in putting this rig together were: power, portability and clarity. The Stewart and Demeter are a good match. Running those cabs, there's lots of clarity with my active, extended-range basses. Plenty of clean power but a nice, punchy tube front-end. The Demeter allows me to basically run my basses with everything flat and then cut rather than boost to taste. So far, everything seems fine. Rather pricey but worth it.
