I couldn't agree with you more Ian. That is why the wife and I go to the "Y" before I load my CP Spacestation and head for a gig.
I am really afraid you can't compare this with Bose of anything else.
If I was to go back gigging regularly, I'd seriously consider the SpaceStation...much more simple than having to set up two powered speakers in stereo.
I played through a single Bose L1 and the experience was less than satisfying, especially due to the fact the Tyros4 doesn't collapse well into mono, and having two Bose to set up wasn't what I'd call ideal, although, I must admit, the sound of them was pretty awesome...then again, so was the price!
And you are right...you just can't compare the SpaceStation with Bose.
I trust your reviews Bernie, and, I've seen a lot of other positive comments on this great new system, so I suspect I'd have to have one if the conditions were there.
Ian
