I use Serato Scratch Live. Not Serato DJ or itch. To me the Serato SL boxes brings out a really great sound out of my digital files. I enjoy using the equipment that I had prior to going digital. Such as my 1200's and Pioneer decks. This was one of my main reasons for becoming a SSL user. I'm not happy that Serato renamed itch with the same name. I guess it was done for marketing with the controllers. I love SSL for the stability, features and sound.
