So, I'm using Traktor and an MC-6000 for pretty much everything. 'Had the chance to demo SC-3900 decks and Denon's 1700 mixer a couple weeks back and now I'm suffering from not really enjoying my TP & controller setup nearly as much. Having command of the large scale hardware just really changed something for me. I felt so much more connected to the music and the audience with the 3900s. Before this experience, I never had any issues getting around with 4 decks on the MC6000. Now, it seems almost claustrophobic and un-engaging. But it's not like my setup doesn't "do" everything the CDJ type system did. Admittedly, I've been more than a little underwhelmed (annoyed, actually) with Traktor since the remix decks came on scene, as they essentially neutered my once all-powerful controller. Nevermind the fact that I just cant find a use for them.

So here I am seeking opinions.

What will I loose if I take the plunge and go with 4 decks of Denon 3900 (or 2900) & Engine vs. Traktor and the controller? Am I crazy? Is there a side of this I'm not seeing? Or is this just me being unhappy with a Vette after driving the Ferrari?
