Ok, I'm wanting to spend around £600 on a mixer. So far I'm most likely to get the DJM600 (Pioneer) as I've used it, I like the effects, smooth and good sounding mixer.

However, I don't want to discount other mixers. These are the others I'm looking at and I want to know any first hand experience you've had with them. How they felt, how easy it was to use the mixer to set up your cueing in the head phones et..., sound quality etc...

Denon DNX1500

Allen & Heath X:ONE62

Vestax PMC37Pro

Anyone used these and can tell me what they think is best. I want the clearest sound for the smoothest mixes, which would suit me best?
