I did, I owned couple of setups (CDJ2000 nexus 1 and 2, DJM 900 NXS also 1 and 2, DJM 2000 nexus). CDJ’s 2000 Nexus 2 for a very short moment after I bought the SC5000’s in almost same time, but pioneers were mostly later on sitting in a case… Nothing really superior or even impressing.
I used the CDJ’s mostly as Traktor controllers due to their limitations. Denon setup got me free from the macbook/traktor usage. Just still missing sampling in a way the remix decks are working with 2 normal traktor decks, but that’s a different story. I like also the Full metal front plate of the SC players. They are way more sturdy than flimsy pioneer plastic. Also the jog wheels are way better (aluminum) not plastic noisy grinding like CDJ’s have.
I am definitely not looking back to CDJ’s at all. Even since beginning of 2019 I always had Prime setup provided on all my gigs. The booking agency I am in took a good care of this, that my rider was always fulfilled - worst case scenario was a DJM mixer, but always Prime decks. In general I am very happy with Prime’s and now I am aiming to upgrade from SC5000 to 6000’s (all 4 decks).
