I also received comments when I switched to the S900 from the 3000.
While I didn't receive compliments when I upgraded from JBL Eon10 G2s to FBT Maxx 2As, I never more get any complaints that I am playing too loud.
It sounds like the Bose are really in another league - especially in stereo!
The biggest compliments I ever got was when I upgraded from the Suzuki Q Chord
