I upgraded from a firebox to the n12 and the difference in sound quality is amazing and the firebox is a brilliant bit of kit imho!, but i've never enjoyed recording and mixing music more since i got one and feel no need to ever want to change again (unless i win the lottery!!), there are of course a couple of downsides with it, like no saving of settings after a mix but i use the track sheets which you can d/l off the yamaha site so that's only now a very minor inconvienience, but overall its an awesome piece of kit for the price.
