I also did not care for the ba330 . it is more powerful than the kc200 so if you didn't like the 300 the 200 would not be better. I bought the bose s1 pro and I could not be happier. It comes with a rechargable battery pack or runs on ac with the same power. It is a little beast. Very powerful and since I got it I very seldom use my bose compacts, in fact I liked so much I bought a second s1 so I can run in stereo. Wow what a great sound for a little system. Just my opinion.
