When I said "Having now played my Yamaha CP33 keyboard with the Bose L1 Compact cranked up" - I should have added "on stage, at the gig location" So everything I have said applies to a live, large room situation. To answer Mac I have tried all three available Bose connections to hook directly with my keyboard ie, 1/8' stereo, left and right phone and 1/4" mono. The piano sounds the same with them all.

Bob your comment "The conclusion to this is no matter what you do, no matter how many different PA's you go through you will never get that killer full grand piano sound you get at home through your headphones or studio monitors" confirms exactly what I said in my last post. I have tried a pair of powered monitors and the pianos sound great but the Bose sounds wrong whatever I do. Recorded music and everything from my computer and synth sounds fine but SOME of the piano patches have much too much bass. Unfortunately this low end Bose doesn't have an EQ to correct the problem - which is why I tried to use the mixer EQ but that created it's own problems as outlined in my original post.

I did a lot of research on the Bose before I bought it and nowhere was there a whisper about piano sounds so I am a little disappointed with my purchase. Luckily SOME of the piano patches are OK and when I asked listeners to comment on the piano sound they said it was fine. Perhaps I am being too picky but I expected more from Bose. Also, would I be right in thinking that most performers are not interested in solo piano sounds - mainly guitars etc.
