The Pioneer DJM 900 Nexus 2 is a great step up from the previous model. Better and smarter circuitry. Better sound, dual USB inputs. Phono/Line on all 4 channels (no more annoying setups!).
Re-engineered FX section. Filter FX greatly improved. An all over great upgrade from Pioneer DJ and at 96kHz 64-bit output. Pioneer steps it up as the mixer of choice for clubs worldwide.
If you have been using DJM 800 or 900 previously. This mixer will make you feel right at home. Same genius design, just a lot better.
