benson compared with anything before the DJM-900nxs2, the analogue sound of the DJM 500 and 600 are much better for turntables.
I don’t know how true it is but I heard that in the early to mid 2000s Pioneer made their new Digital Mixers sound worse on Vinyl, to increase the wow-factor of the clarity that CDJs gave in clubs. If it’s true it definitely worked as part of the marketing strategy.
Eventually people just wanted to use Allen and Heath for the Analogue sound again but it seemed to take a while for people to realise what was happening and its taken until this new line of mixers to get good vinyl Pre-amps.
