@menuki , if I recall correctly you ordered both the DJ's and the DXP, and were deciding to keep only one of them. Which one of them (if any) did you keep? I saw you going back and forth on this thread & the Sig DJ thread, but not sure which one you actually ended up with (or why).
2) My main concern in blindly ordering the DXP is that I've read that the detail isn't as precise as the Sig DJ (or PRO I would assume). Is it a subtle decrease, or very noticeable when compared to the DJ?
Correct, I've owned the Signature DJ's, DXP, and Studio. The DJ's have a, to my ears, slightly better bass response (a tad less loose), albeit it's a bit boosted, not in a bad way though! When it comes to the mids it's quite hard to decide... I think the DJ's just slightly edged out on the DXP's, but they still have very decent mids. Generally, both have warm mids and the DJ's more so. Treble, also not really easy, the DXP has more treble, but it felt really nicely smooth on the DJ's, but the DXP's were never really sibilant to me.
Overall, I think I would've still gone with the DXP's, since the white color on the DJ's got a bit discolored, but that is really just cosmetical. I would heartily advise you order them both and return the ones you don't like. If that is not possible at all, then let me try my best to sum it up to help you out hopefully:
DJ's:
- Compared to the DXP's, more bass, smoother, less treble, might be missing a bit of higher frequencies in terms of quantity to some, but it's really easy to get used to their sound signature
DXP's:
- More treble, not prone to discolorations, a bit less mid presence, which also sound a bit further away since the pads are thicker (less plush than the real-leather ones on the DJ's, might be improved by wearing them longer), never really sibilant though, to me, the bass was just a little bit bloated though, which was also the impression of one of my coworkers who makes music
I now own the Meze 99 Classics and I'm very, very happy with them because the mids and overall soundquality / build quality (materials used beat the DXP's or DJ's by a longshoot IMO) is just stellar, IMO more presence compared to the DXP's, the DJ's mids were very much to my liking though. I really mostly gave back the DJ's because of the discoloration thing (yeah, I'm sensitive LOL) and ´the DXP's because of the bass.
STILL, both are really great headphones but if you get the chance, also maybe check out the Meze 99 Classics as well. It was really hard to decide whether to keep the DXP's, DJ's or even Studio's for a while (which were just too bright for me, lacking sub-bass) but the Meze's are kind of a nobrainer - but, I'm also a sucker for wood and the corresponding "wood-sound" if that makes sense. Wood does kill some resonances, and adds this kind of "signature" wood-feeling to the bass. Everyone who ever heard a wood-headphone will know what I'm talking about, but it's a bit hard to put into words. Imagine it like being able to hear what this particular wood (walnut wood in this case) "sounds like".
EDIT: Wanted to also add a disclaimer: I think the Meze's may actually have boosted Bass above neutral level, by just a bit, (in
most songs the bass just sounds so perfect though) this is not a problem for me at all and their sound signature is very, very addicting. Treble is also pretty smooth and described as grainy to some, to me it sounds pretty perfect since I'm treble sensitive, but there are people who dislike the Meze's, of course. There will never be a headphone which suits everyones taste, but I think I found my practically perfect match with the 99 Classics. There is not even any headband adjustment I have to make... I just put them on and I'm engulfed in their so very sweet sound and the world feels like a better place. I truly think everyone needs some Meze's in their life... they make me forget about all the audiophile stuff and makes me just want to listen to the music - isn't this what it's all about?
Anyway. I'm just a big fan of these.. every part can be replaced, so you could keep them for a very, very long time. IF Meze's provides spare parts for a long time that is of course.
I really hope my answer is in any way helpful to you and the best of luck with your decision!
