I've wanted to get some good open over-ear headphones for a while, but I'm having a hard time to figure out which one I should buy. I have an Objective 2 amp which I use to power my Hifiman RE-262's and seek to find a more analytical and neutral sound. The most important things to me are preservation of detail and soundstage, something that I absolutely loved in the Sennheiser HD800. Unfortunately, I cannot afford those cans (yet), so I'm looking for the next best thing (or should I save up for this?).
I listen mostly to post-metal and other types of fast (punk)rock, although I enjoy jazz too. From what I've read my preference will go to a AKG K701/K702/Q701, but I'm not entirely sure since I've never had the chance to hear them. Recently I've listened to the Beyerdynamic DT880 headphone and they sound really good, but I feel the soundstage is missing and there's quite a lot of bass combined with my Objective 2.
Could someone help me with this problem? Help will be greatly appreciated.
