i'm sorry I never got back to you, i'd say they were near perfection for what I was looking for. Deep full impactful bass when it's called for, very dynamic, after nearly 2 weeks thinking back i'd say the soundstage could have been bigger, honestly felt like the soundstage was bigger on the mr. Speakers Aeon Flow open or AFO, but the Afo and other headphones had harshness on tracks where the d8,000 didn't. E.G. Dance of the Sugar Plum Fairies where the chimes come in, some headphones render a sharp piercing sound at certain volumes while the D8000 didn't in the slightest. Atrack that can sound a bit muddy even on high end equipment is old souls from inception, the intro can sound muffled, keep in mind this is at higher volumes. The d8000s I felt distinguished each nuance of the piece. Also keep in mind I was in a noisy environment. It might seem weird to say but I felt like imaging on the 8000s was spectacular while soundstage a bit narrow, I want to hear them in a quiet setting. Maybe a touch to much treble, but the adjustment would be so minoot. Can't emphasize that enough. mids were right where i'd have them, and if i'm nitpicking the treble, i'd say tighten up the bass the tiniest of tiny amounts. The AFO treble didn't sound really sharp BTW, but mor so than D8000. In the end, for me anyway, knowing these will be out in the wild, I may pick them up one day, but I went ahead and got the AFO as I feel like I can EQ out the things I don't like about it. I don't feel like the D8000 is worth the amount it retails for when I can get the AFO for literally $3,000 less and get a headphone that still complements my HD800S and punches well abuv it's price point when compared to higher priced headphones.
