Hmm, well after listening to these for a while I'm noticing something. The bass impact does not compare to my HD 650's. It's detailed (but so is the HD 650) but simply cannot produce that deep deep impactful sub-bass of explosions in video games, movies, etc.
 
Using an equalizer I've realized that my HD 650 is just toned down in the treble which makes some things (voices, gun shots) sound less crisp unless corrected with EQ.
 
Sadly, boosting bass on the AD2000 does not make it impactful, while boosting treble on my HD 650 does retain the impactful bass so I get the best of both worlds.
 
I originally bought the AD2000's to be an open headphone that sounded like my SRH-940. Ultimately they do not sound nearly as detailed and crisp as the SRH-940, even after being equalized.

Anyone able to tell me how the AD2k's clamping force compares to AD900?

The lack of bass impact and extension are the weaknesses of the AD series in general although I find AD2000 to have the best bass compared to its siblings.

I just bought these as an upgrade from my ad900 and I couldn't be happier. The headphones have a much better build quality to them, as big as the gap from the Ad700->Ad900. The bass is an improvement over what I considered near perfect on the Ad900, the highs are excellent, but the mids are...Holy cow. These are mean headphones and I love it.

I'm looking for a new DAC to pair with my Ad2000. I have an O2 amp and my iBasso D4 currently that uses dual Wolfson 8740 DACs and am wondering where I should go next. Any ideas?

Is anyone able to comment on precisely how low the bass on these extends before rolling off, in Hertz? I'd appreciate it!

~25Hz

Dang. That's pretty great. Man, the more I read, the more my supreme temptation grows. If I pour libations and offer a sacrifice to the Head-fi gods, perhaps one will pop up in the FS forum sometime soon. My poor wallet.

It all hurts man, all of it.

Make a post looking for them, I had luck that way.

Thanks. I'll try it out. I noticed that there are already a couple WTB ads for AD2000s though, so looks like I have some competition.

 

[keanex]

It seems that the Ad2000 are something that people buy and keep. I know I never plan to get rid of these!

 

[manveru]

Well, I'll keep my fingers crossed. I've seen plenty of archived sales, so it's not hopeless, but yeah not sure how often they might actually come up.

Unless you have a compelling reason to upgrade, I'd recommend not bothering and just enjoying the music. As far as a DAC, I have no substantial experience with anything in your price range as almost all of the sources I've heard have been the >$2K MSRP variety (and most have been CDPs, not standalone DAC units). The only thing I can remotely offer is to upgrade to an AC-powered source, maybe one in the $500-$1K category.
 
Though I'm not familiar with the O2 amp, I have to add a recommendation here for a Dynalo (or M3) regardless - out of all the amps I've heard with the AD2K (which has been a lot over the 5+ years I've owned them), those amps have stuck out as being the best, hands down.

Thanks, I was looking into the Dynalo based on your review and praise of it. I think I'm going to look into an HRT Music Streamer II since I've heard it's very neutral with good clarity.
