Thom_Fuckery …tbh there’s a lot of nonsense talked about them, its just a preference really. I first used a Rane 2016 in the mid-90’s and loved it so have owned a few…. moved to more modern-featured mixers for a while, then back to rotaries again.
The more recent ‘boutique’ mixers are all about sound quality really… less bells-and-whistles in the signal path = the best possible sound. This one is quite niche even by rotary standards, the bloke that makes them works to order by hand in his workshop, but are used by surprisingly diverse range of DJ’s… Gilles Peterson, Mr Scruff, Theo Parrish, Dixon.
