    These are Anaheim meet measurements and given meet conditions, distortion plots are sort of meaningless (no SPL calibration and background noise).

    Cans belong to bassluver @Luckbad. And indeed if one is all about the bass, these will not disappoint. IMO these are comfy and very elegant. The cups are claimed to be made out of Radiata pine which I guess is pretty sexy. These are also supposed to be hand made in Japan. They are big, or so she said.

    These seem to be relatively hard to find. From what I could find, they sell for about $9980 (HK) or about $1280. This probably is MSRP and dunno what the real current market value is.

    My impressions are meet impressions and will be brief: They are bassy and not bad. Others with way more experience with these should be able to fill in the gaps.

    Measurements (preliminary - these were sort of quick and dirty from the meet):

    Thanks! I'll try to drop them off at your place for a weekend sometime soon for proper measurements.

    I'm guessing CSD is pretty accurate. The cups are resonant and are part of their charm. They're barely damped.

    It's what makes them astonishingly good with classical music and kinda meh with faster rock.

    I'd say 90% of my JVC head time is classical or electronic, both of which it does very well.

    Most other genres get the Sennheiser HD650.

    Not far off from this:

    I have been wondering how to reduce the slight grain in the treble. Now I know it's definitely there since my subjective impressions match objective measurements.

    A couple tubes I've tried help at the cost of bass impact. The Master-11 also improves it, but I can't take that to work.

    Those goldenear plots do look close to what we got at the meet! To check other things out I would need more time with them though.

    Dunno many portable amps that would mittigate grain-ness w/o sacrificing bass either.

    What I find interesting is that I heard barely any bass at all when listening to them. Even when I put pressure to make sure the seal was good.
    I tried to play with the fit a bit, to no avail.

    I guess it makes sense now why people dismiss the HE-X when I hear them as an excellent headphone: they match my head shape. The JVC clearly don't...

    Yes. The fit may be a bit loose for some. If I get them from @Luckbad, I'll try to make some measurements with less-than-perfect seal as well.

    We should've pulled the Audeze pads off your HE-6 and put them on the DX2000. They fit perfectly and probably would've given you a better seal since you know those pads work for you.

    The JVC DX1000/DX2000/DX700 pads are weird as crap. It took me weeks to figure out how to get them to be comfortable and seal well. I used Audeze vegans for about a month before switching back to stock and finding a way to get them to work for me reliably.

    P.S. One of the measurements we took had a bad seal and the bass was indeed largely missing and super rolled off in the sub-bass.

    Good to see some measurements from this headphone, though considering how it measures up to the TH X00, I'm finding it hard to make the plunge and purchase one... has any one gotten around to modding these?

    I know a few people have tinkered with dampening behind the driver. Some have turned the drivers around (then immediately changed them back).

    A few have aftermarket cups on them.

    I thought they were cheaper. Luckbad tried to get me to buy a pair a while back ( :p ) and they were a few hundred short of $1K.

    DX1000s can be had new for less than $700. The DX2000 is the same, it's just the anniversary edition.

    There is a used DX2000 on HF for $600...

    If you were to try to dampen the resonance of the treble spots, what would you put behind the drivers?

    The drivers are mounted with screws directly to the wood cups and there's not much damping material back there.

    The DX2000 is identical to the DX1000. Here's a cutaway:

    The back of the driver looks like it has some film covering the hole in the cross section. Could that be reflecting back the higher frequencies?

    I would take out that piece of paper in the rear of the driver and replace it either with tea bag cover (not kidding), packing foam (will provide more details on which one) or really just about anything else that's a bit more breathable, or... alternatively, some kind of softer paper like tissue paper (toilet paper not recommended because... reasons :) ).

    Wouldn't really go overboard with damping in the rear because I think that'll detract from the bass, and I don't think that's desirable.

    Would coffee filters make sense as a dampner?

    Yeah. Try anything that's more breathable and less rigid than paper, really. I think the rigidity of the paper kinda plays into some sort of reflection... so softer materials tend to be better at diffusing this kind of thing.
