I have the S4 and use it along with my technics 1210’s.Was tempted the other week to maybe swap the S4 for a Z2, but after mulling it over I’ve decided I may swell keep the S4 as it works very well with my turntables, and if I get the odd gig I can roll up with the S4 and macbook in my magma backpack, easy,simple and very effective set up. At home all I mix on is the turntables now though as its more fun
