Very interesting how much love the HD800/s is getting :) Haven't heard these yet, nor the HD820, Actually most of these! :) I do want to hear the Aeon Flow Open as well as the HD8xx's. The Utopia is amazemoid - I instantly loved it. I do have the HD650's and prior to these HD580's i think.
I have had the HD800 for a number of years now. The highs are not “harsh”. This is a pure reference headphone. If you listen to jazz, classical, instrumental with high res FLAC files thsee cans cannot be beat imo. On the flip side I would not suggest these if you listen to mostly rock, etc.
The HD6XX happened because of the release of the new model, I don't think there will be a 800S at half the price or less anytime in the foreseeable future.
My understanding of the 2 is a tuning different and a ring on the driver of the HD800s that dampens the highs. I believe the drivers are the same between the HD800 and the HD800s. I do not own a pair of either so I can not confirm.
With the launch newer hd 800s which is the rectified or tuned up version of the hd 800, the value of the hd 800 has significantly depreciated but we dont mind paying $500 for it, do we?? Drop it within the $500 dollar price range and we'll grab a dozen !!!
