I use it for 1 year after having numark axis 9, pioneer cdj 200
I love the most, reliability and ability to "eat" all the old burned cd, some effects are not bad as the delay and filter the other I find them better in pioneer like flanger ... Not bad at all: the alpha track that lets you play two tracks on one cd, it is used quite often and the creation and editing of loops (loop) is very accurate, Sampler slot cue point as well. However I like less accurate tempo pioneer on this side is more reliable for me but who cares, a good dj to hold the ear with time
I like the least, the system fast forward, two buttons would have been simpler ...
I put it to 9 and also for instructions frankly not always easy in fact it's not really a platinum single, but once you understand it's not much limit. To know that I had to mix a full evening of the CDJ 1000 and although some of my cd did not pass while on my dnd9000, anything goes! Denon is well for me as well as pioneer to date
