At present, I use Serato Scratch Live with the SL-3 on two Technics 1200-MK5s. I love the flexibility that Serato and digital music offers, but I do have a pretty healthy collection of classic vinyl and I love to throw that down every once in a while. I also use the Pioneer DJM-800 mixer, and Allen & Heath Xone XD-53 headphones. To echo David Guetta in regards to the DJM-800, "it is my favourite toy"!
I love all genres of music, everything from house and trance to urban, to metal, to country and even classical. My sets will often span many genres, but I admit, I do like to play a lot of my biggest loves, funky, electro house.
