I think the SA-1000's split cabinet system gives far better portability (compared to the Traynor K4), as each cabinet is only 25 Lbs.

It would be interesting to hear how the stereo separation works on a cabinet that's only about 18" wide, but it may help with the phasing problems associated with some keyboards.
