After getting them last Friday I finally managed to open them. My own christmas present.
These headphones do not have the HD650 treble (latest model with the black box), they are not kinda 99% compatible to your music collection like the HD650 . If you expect them to have the same curve then I have to dissapoint you.
However they are closer now than before and this is damn good. :[]
I will upgrade my DAC in February and go for the Gungnir Multibit, until then the X7 LE's PCM1792 in Direct Mode (a relais releases the DSP thus no "dirty" processing) has to serve all conversion needs to the Valhalla 2.
This are just the first 30 minutes but
the peak is definitely gone in the extend it annoyed many people (but didn't many others).
The headphone is still bright though but noticably improved. A lot of stuff you will listen to is now noticably easier to tolerate. I only threw problematic tracks at them so far just to see what changed as their infamy has a special place in my memory and knowing the HD800 very well I also know its weaknesses that stand out easily, thus I start with the worst. The HD 650 wins in inoffensiveness EVERYTIME. Sometimes a track is so offensive that not even this beautiful headphone can save you from hitting the roof while making this face:
"
Bananarama - Robert de Niro's Waiting",
"
Nicole - Ein bisschen Frieden"
Both are kinda problematic but EASIER listenable now. It was harder before as the special brightness of the first track automatically made me lower the volume, I can listen to it better now and louder, just not loud (80db+). The same for Nicole as Nicole's SSSSS also appears on the HD650 (you can listen to them louder here). Don't worry.
"
Elvis Presley - The Wonder of You" I love this song but that tsssss in the beginning.... It's finally tolerable and no barrage of needles that hit at the same time.
"
Manowar - Warriors of the World United - Live" Can be listened louder now finally.
"
Public Enemy - No Sympathy from the Devil": The HD800S doesn't look good here but What were PE thinking? It's borderline on the HD650 already. Don't listen to this track loud. (also not on the HD 650 either)
impressions of soundstage, slam/punch/kick and imaging will follow.
