Get your Pioneer serviced. It is an industry standard. You will never find a Denon mixer installed in any big clubs and no small clubs would pay the cost of the 1700 which is rumored to cost more than the DJM-800. If you want to be different then the Ecler Evo 4 or Evo 5. The Xone 4D has A & H's filters and nothing more.

looks like the denon will cost around 1700 or 1600, so yes its more than the 800, im taking my mixer for service tomorrow :) now the Evo 5 looks sharp,. anyone who owns one ? i would like some feed back about it

I used to own one. What did you want to know?

`well how is the sound on it ?

Equal if not better than the DJM-800. The effects are pretty dope also.

Care to elaborate on why you USED to own one, but don't anymore?

It was simply to big. I couldn't realistically bring it to any clubs I did and it was a little overkill for the house. I sold off a few mixer I had and kept the 57. This is getting sold next to go for either the Evo 4 or the DJM-800.

I also own one, and love the mixer. Used to own the NUO4 before that. Ecler makes some nice stuff, not many people in the US tho purchase them because denons and pioneers are pushed at GC. If interested in getting one let me know, I am a reseller and can get you one at better price than online.
The effects are awesome on it, shitload of midi mappings. Easy to bounce back and forth between setups. for instance, if your using timecode and you need to play audio CD. You can click button that (you need to map it) that will take that channel from TC(TimeCode mode) and switch to Audio. Not messing up the other deck that is playing TC. This is awesome if you ever have a hd crash and have backup music on cds. Plus many other features.
