Decided to replace our existing (but fully working) Behringer Pro Mixer DJX 700, but sadly, the sound quality from the new VMX1000USB was no where near as good. Lots of features and connectivity on the new model which we wanted, but the sliders just felt too loose / flimsy with little response / feedback. Interestingly a colleague has the previous Behringer Pro Mixer VMX1000 and this sounded great as well - hence the reason for our purchase - so either there were a lot more compromises / cutbacks made on this new VMX1000USB model, or we just had one that did not perform as well. In summary, if you want a mixer that has lots of features and connectivity at a brilliant price, this model can't be beaten, but the sound quality is not the best, which is a shame compared to other Behringer products that we have owned.
