I just bought a pair to replace my cdj 1000mk2.

Regarding the differences "aesthetic"
- Pitch metal
- Key "re-loop" Same as the master tempo, but lights up in orange (and therefore as the loop)
- Protection of mmc by a sliding cover

For changes more "technical":
- New graphic display (more information and better visibility), is particularly noticeable at the aficheur wave.
- Display in the center of the tray back in the tray, so seems bigger.
- Reading mp3
- Possibility to adjust the resistance of the plate is to say:
Bottom left wheel rule, the board is very "light", a back spin, and it turns bcp, much like the CDJ 800
Bottom right wheel, the plate is less flexible, much like the 1000, the first name.
In the middle or slightly right (gray area), feel like the mk2 looks like because roulments seem different, a little more fluid.
- Finally, to save her curls possibilté ds hot-loops, which allows to have four loops at the same tps, ca c is cool!

In short, qqs amliorations, much like the 100 MK1 mk2 qd is to retire lol.
Still very intuitive and a bit faster even than the 1000MK2, especially during a scratch after having made a search rapise, a loop ... etc.
