I traded DNJ my Roland E50 for his HK Nano last summer. I love it. Getting another so I can have twice as much power and for backup. One, in stereo, covers the room I normally play very nicely. Around 75 people. There is a lot of headroom left. I haven't really cranked it all the way up. I like the nice warm tone a lot.
Not better than the Bose, but different. I just like to change things up sometimes.
