I found the ATH-W11R to have too much of an accentuated upper mids and lower treble and got rid of them, and naamanf's W5000 were similar but with even less bass. I did not like either. They were grating on my nerves, similar to a CD3000.
I enjoyed the ATH-D1000 digital phones but felt the treble was a little too rolled off, but they did remind me of a Denon D2000 or HD600 a little (ignoring the treble) so they were redundant and I sold them. I enjoyed plaidplatypus's ATH-A900 Limited and my -=Germania=- modded recabled A900 Art, but felt they lacked the precision and detail of D2000 or HD600 and are mid-fi phones (but with good soundstage and bass and fun). But at least they don't have the slightly rolled off treble of the D1000, and didn't do anything particularly wrong except for the congestion in complex musical passages .
The AD2000 are more refined and detailed, but a bit more forward than the ESW10 and remind me more of a dynamic version of my re-cabled ESP-950 electrostatics. They didn't have the odd tonality and frequency response of the W11R or W5000 that I didn't like, but they also didn't have the speed and transparency of my stats. I was more aware of the driver next to my ear than with the ESP-950. The AD2000 are very good, just didn't fill a niche in my emsemble of phones.
So, I actually enjoy my ESW10JPN more and sold the AD2000 yesterday and kept the ESW10 which I used more. ESW10 are kinda like a closed RS-1, and very full and rich, clear and transparent with good bass and smooth highs (after 100 hours burn-in). The ESW10JPN mids are also more forward than my woodied re-cabled D2000 with better midrange detail, but the bass and soundstage of the supra-aural ESW10 doesn't keep up with the Denon or Edition 9. I want the ESW10 mids on my Denon D2000 Ithe mods make it close but not there yet).
I do not regret the $540 shipped one bit, especially with the $128 cash back I'll have going into my paypal account before the end of the year.
