They both have the same ultimate function, so I think it's perfectly valid to compare them.

Thanks for your reply. could you please elaborate on their differences then? (I'd be even happier if you could add the l3000 to the equation...)
The most apparent difference for me is the timbrel coloration of the DX1000; it has a warmer, thicker sound whereas the TH900 sounds relatively clearer and more open, especially in the midrange despite the minor suck-out. Similarly while they're both bassy, it's cleaner on the TH900 whereas it has a thicker mushier sound on the DX1000.
The DX1000 is closer to the level of the D7000 for me. The TH900 just outclasses it in every respect, save for having a more fun coloration which some might want depending on the context.
The L3000 is even more limited in application for me personally; it has such a distinct "sound" that I really don't like it for anything other than certain rock & metal tracks. I'd characterize its overall sound as aggressive. I don't think I've ever had as dramatic a love / hate relationship with a headphone as the L3000. But that's just me.
Did any1 see any frequency response graphs on DX1000 btw? I don't think I ever recall seeing it.
I did find THIS extract though in a comment on audiocubes:
So the JVCs are a bit bassier I assume especially due to not as "clean" quality bass response as in the Fostex. 12dB is suprisingly much for such a priced headphone if accurate, it should easily have the "expensiest vs bassiest" crown. I'm unsettled which of these 2 to aim for in the future when I think I have the cash to drop on such pair of headphones (I just don't feel comfortable spending that much on a headphone just yet). The JVC sounds almost like being slightly too bassy and the Fostex maybe just not quite as bassy as I was looking for. :P I don't like V-shape sound and generally like a quite warm & forward sounding midrange as possible to go with a boosted bass and highs should stay neutral and not emphasized. I think I enjoy the lush mid-character that wooden cups brings. Is JVC more suited to me than Fostex perhaps?
Hi! guys,
I got Denon 5000, and about to upgrade to Denon 7100 or Fostex TH900, does anyone had the chance to listen/compare them?
And do the TH900 still have "swivel" problem?, I assume that from poorly assembled at the factory?
Not sure it's worth 800$ extra for platinum foiled logo on the cups.. =P
Going to use the new Burson Soloist Amp. with them, have read as much post in this thread and other threads about these too but still can't make up my mind.. =P
Many thanks!//Tobias

You'll have to note that this is all very subjective, but I walked into Fujiya Avic in early August toying with the idea that I may consider swapping my Fostex TH900 for the new Denon AH-D7100. Possibly the demo D7100's were too new and didn't have sufficient burn-in, but I walked out of the store keeping my TH900. This was my opinion then :-

Since then I heard the D7100 one more time last week in a different store, and I'm still keeping my TH900's.
As for the swivel problem, I talked to Fostex today (there was a Fujiya DAC festival) and mentioned to them of the concern on the net. Their recommendation was just to send it back to the distributor. Whether they swivel problem still exists or not, I don't really know but it seems to be an easy fix - in my case, my TH900 which had a swivel problem, broken & scratched cup was fixed and sent back in 2 days. But yes, I do live in Tokyo and (unbeknownst to me till today) Fostex seems to know me, and what car I drive too (that's a little scary :D).

Thanks alot for the respons!(fast one too! ;D ), great to have someones opinion that have listen to both of them!
That makes me concern, I live in Sweden and have to import the phones.. have stores here that have 7100 next week on shelf and for demo.
Would make me jump from a building to send them all the way back to jap./au/us..
Hahaha!, thats great! maybe you can hook me up on a good deal then!! ;DD
AnakChan: that is scary! must be the tracking chip in the Fostex, that gives your whereabouts, you can just sent it to me to test the theory, might not be the international chip, lol
Still have my eyes on this beauty

I haven't heard the Denon 7100, but I found the Soloist to be a great match for the TH900, besting several solid-state amps 2~3 times its price. The Soloist/TH900 is my current setup.
*thumbs up!*
Thats really great to hear that someone is using the Soloist with 900's!, damn.. I was leaning towards the 7100's, but now more back again to the 900's...
Heheh, nah, it's cos I drove to their office and I'm guessing they don't get many end users turning up there. Most of the time, manufacturers deal with distributors/retailers when it's post-sales support so it was very rare and very comforting that they welcomed me instead of sending me back to distributor. At least in my experience Fostex has impeccable service.
I had the D7100 in house and thought it was inferior to a new D7000 purchased in April and I clearly prefer the TH900 over that stock D7000.
One thing to note is that I have two D7K’s. One from ‘09 that I had to mod for me to like and the one I just purchased. The new one sounded great out of the box. Tyll acknowledges this and InnerFidelity has measurements that back up this phenomenon. Denon/Foster must have tweaked the design over the years. I think this was a factor in all of the polarizing opinions.
If my opinion on SQ is accurate, that may explain why Denon so sheepishly christened their new product the D7100 and not something like the D8000.

Did you keep the D7100 in the end or return it? Out of curiosity, how long did you burn it in for and did the signature change much after burn-in?
(and if we had this conversation before, I apologise as I've clearly forgotten :D).
I did return it. There was no burn-in done at all. If anything there was something weird happening with the earpads that drastically changed the sound. It went from sounding awful to being acceptable. My new D7000 has only a few hours on it, so neither one was burned in. For that matter my Fostex also has low hours on it as well.
I don't dispute its effects, it's just not something I practice.
