In the brief few days that I've owned the Compact I have changed my mind regarding the Bose L1 line. They are definitely a new direction in technology and they definitely do produce some very satisfying sound out of those contraptions. And they are relatively expensive for what they do.
I've used many good PA systems and there is no doubt one can be completely satisfied with the output of a well EQ'd and setup system. I thought my recent small setup of CM-30's and an EV sub (if necessary) was quite good. it was only three pieces and a few cables. The Compact, though, is my new system of choice. Why would I pay $1000 to replace a perfectly good system? I think I can only explain it by saying that the sound is appealing, the weight factor is way in my favor and, hell, I guess I just plain ol' like it.
I feel that those who are happy with their present systems should probably stick with them, but should make every effort to listen to a Compact used in a similar circumstance to your own and then try one for a job or two. It's a very subjective decision and only you can justify the payout/payback equation. I happened to sacrifice a keyboard for my Compact and am happy I did.
