One of the
HR-16 User Reviews at HarmonyCentral.com talks about the HR-16B and recommends it over the HR-16. Here is pretty much what it said, but you should read it yourself.
(Quote .... "twice the sounds of the original HR-16, better OS version ... The black HR-16B has better sounds than the regular grey HR-16. More sounds, and better suited to techno as well. Nice cymbals!! Hi-hats and Rides are really fine!"
