Similar bass and treble in the sense that both are fully present at both ends. Its weird because I have read people describing the Denons as Midrange-recessed and I never agreed with those opinions. But next to the HD 800, I begin to see what others are saying in this regard. The HD 800 manages to sound more forward in the midrange without losing clarity -something I've never heard in any other headphone, and it makes the Denon sound thin in the middle by comparison.
The last time I listened to the HD 800 (over a year ago), I found it somewhat cold and analytical, overly bright and almost thin sounding. Maybe its my Carver receiver, but this last audition the HD 800 seemed fuller and warmer without being too full and warm (planar sounding). Bass maybe not as "full" as stock D7000's, but very comparable to my Lawton Audio 7000's - which are tighter and better controlled than stock.
I have been having hearing issues lately (15+ years of tinnitus and hearing loss) and I have become overly sensitive to sibilance and treble spikes. During this most recent period, I have been listening to my Denons less and less, and I think its because of the treble. The HD 800's, while possessing the sparkle I like, didn't seem to trigger my treble sensitivity.
This may not make sense to anyone but me (especially considering my hearing issues), and it might just be my evolving/changing taste or preference, but this is the best way I can articulate what I'm experiencing.
