I am looking for a new pair of open back headphones to complement (replace ?) my HD 600, so I appreciate any suggestions. (~$600 budget)
What I expect to improve over the HD 600 is a better bass extension, a little more body (warmth?), bigger and spacious sound stage, slightly less forward, clearer but with the same amount of treble as I am quite sensitive to treble and IMHO an over accentuated treble negatively affects the timber.
In my search for this I tried the HD 660S and while it offer some of my desired advantages, its rolled off highs was a deal breaker for me, even if I got those at a great price.
I tried the DT 880 600 ohms, and while I liked it smoothness and open stage however their over accentuated treble peaks was just to much for me.
Currently I am aiming to the ATH r70x as based on some reviews and from its frequency response seems a good option.
Another one I am eying is the same DT 880 premium edition but its 250 ohm version as based on this review, seems to offer less treble and its frequency response is quite similar to the HD 800S (keeping all distances) so this intrigues me.
My current gear is an Ares II DAC feeding a RNHP / Gilmore Lite MK2.
Thanks in advance!
