Its odd seeing the digital generation move to analogue and the analogue generation move to digital all at the same time.
I started on controllers and moved to DVS and analogue. imo, controllers, on their own, are boring.
If you respect the music that you spin, you dont wanna smash the shit out of it with effects, you wanna blend them up nice. With vinyl this takes care and patience, with digital it can be ridiculously easy. Which leaves you with a lot of time on your hands standing idle, drinking too much or excessive EQ tweaking.
I do agree with you on setup times though, its a pain in the arse dicking around with RCA's.
The X1 will handle all the transport controls, but you still need to plug it into the mixer like your DVS setup. It doesnt handle EQ's when you get it out of the box, you'll need to augment it with mappings. For such a small controller, you really dont wanna have to be switching control layers because you will eventually lose track of where youre at and fuck it up proper.
The NI series of controllers is the best imo, there are many more that are well made too. I liked reloops stuff from a while back, theyve gotten better too. Denon also make some excellent hardware.
If you can hold off till summer, head to BPM at the NEC in August and check out all the controllers in person. They really vary massively in quality of components.
