I'll start by explaining my situation: not even a year ago I purchased some DT880 Premium (250Ohm version), but I'm not really satisfied with them, as I can't stand the overly bright sound signature. Now I'm considering two solutions to the problem:
1) Buying a new pair of headphones (choices are HD598, HD600 or HD650, because I loved how my PC360 sounded and I feel like going with Sennheiser);
2) Buying a new amplifier to pair with my Xonar Essence ST, and that would be the Objective2, to try and fix the bright signature.
What would you guys say? Do you have any other recommendation to make? Thanks in advance.
