Pioneer CDJ-350 VS Pioneer CDJ-400 – Comparison

http://www.djcdplayer.net/specs/pioneer-cdj-350-vs-pioneer-cdj-400-comparison

sadly they discontinue/legacy my poor CDJ-400's

Current Versions:

Firmware - 1.33

Drivers - 1.007

Thanks everyone, Hmm i may have to go with 350, the .WAV is very important and newer MP3 format is important to me. Also load times seem to be a fraction of the 400...

Has anyone had any issues with store bought mp3s not working on 350?

Have you considered the 850?  It's a larger format with very similar features to the 350 and not too much more cost-wise.

Suggesting CDJ-400's was not my intentions infact offered a link wit CDJ-400's Vs CDJ-350's review & look for the fine print they discontinue my CDJ-400's obviously shows theres no support for em. Plus wit CDJ-350 includes Rekordbox so obviously he wont need any Hardware Dongle/Rane SL1, 2, 3, 4 he has included wit CDJ-350!! or CDJ-850 FTW!! Too!!

@Pulse - if i can find a good deal on 850s because they seem to cost 200 bucks more which adds up when you buy two lol plus i like a smaller footprint on my decks because i have very little space at home and if i need to bring them to a gig they are a lot easier to carry...

anyway, i'll be looking into some 350's instead of 400's you guys have convinced me (i'll also keep an eye out for 850's)

@DjDedan > Obviously cost and footprint are a big factor - just wanted to make sure you knew all your options.  ;)

I own a CDJ-350 and would highly recommend it, and it also has an effect similar to one on the CDJ-400 which is loop divide - and it's a fantastic unique addition to the deck that you won't find on any other current Pioneer CDJ - even the larger, more expensive models.
