Summary: I bought my first DN-X500 in 2006 when I retired my Urei 1620 in favor of a smaller and lighter mixer. And after 7 years decided to buy another as a backup and incase Denon discontinues the mixer. The DN-X500 is one of the best mixers you can buy period. It is very reliable and sounds amazing. It has plenty of features to run any gig wether club or mobile.
