Hello, I use the SI601 for 6 months is an exellent quality over price, it possde 8 DSP effects, 4 banks, so rather good team. The only inconvnient that may have to find is the lack of synchronization effects in bpm. Actually this is my first hardware mixing, so I can not compare with much MODELS. Pioneer cdj 800 mk2 is a prs can the equivalent of SI601, but not both team and is much more expensive. If I had to redo the purchase of my turntables SI601, I think I Do not hesitate, go there eyes closed!
