Just looking for an upgrade, no budget really.
What I like about my current phones is that the sub bass is really nice and I can feel a significant amount of depth in tracks. However at higher volumes they're definitely too bright for me and I'm a huge treble whore. I'm not bothered if its open back or closed because they will be used exclusively at home anyway.
What I have currently is:
Amp: Neco Soundlab Mosfett Amp
DAC: Audio-GD NFB-3.1
Headphones: Ultrasone PRO 2900 / ATH-M50s
The sort of music I generally listen to (but not limited to) is most forms of Electronica (e.g. Trance, House, Electro) so some phones suited towards that would be best I feel, but I don't want something which is literally a one trick pony and there is some classical, rock, industrial music in my library which I don't want to be completely neglected. Although the higher end phones I assume won't have this problem particularly.
