Hey there, thanks for your reply! I am looking for a mostly neutral signature. In fact I would prefer to have neutral, and I don't mind to EQ down parts of the treble myself (from my testing I have found that I am a bit sensitive to the 2kHz area as well as the 6 to 7 kHz area).
There is also the fact that i am a hobby musician. I mix and master my own tunes on JBL LSR308's but I work out of town so I need a good set of cans too. That is where having a neutral HP would be beneficial.
Right now I am using the Oppo PM-3 and -when possible- the Audeze for those high freq details that are slightly harder to hear on the Oppos. I also highly enjoy both for music listening.
For amplification, I use the Oppo HA-2SE through a Fiio X1 or the Samsung Note Edge while on the go. I use the Universal Audio Apollo Twin Duo Mk 2 for my audio interface when on my laptop. I am not sure how much power the amp has, but it seems plenty. I don't have a plain desktop amp at this time and never have.
In addition to what I own, I have heard the V-moda M 100 and I thought they had excellent bass, but more than I need. Don't get me wrong, I love my bass, and prefer more of it than less, but those had too much. I have heard the beats Studio and they had a nice soundstage, but otherwise the quality of the sound was quite far below my standard for that price. As mentioned I owned the Bose QC25 and found them decent, but not very high quality, and a bit of an uneven frequency response that wasn't too far off neutral, but not what I'd want in more expensive cans. I have also heard the Audeze LCD-X as a demo and I liked them a lot. A lot! But there was something a bit funny inthe treble, I can't quite describe it. It might just be me, but I strongly believe it could use some fine tuning.
Having said all that, I am considering the Mrspeakers Ether C Flow, or perhaps the open Ether Flow, if the difference in quality and soundstage is noticable enough. From reading Tyll's and other's reviews these sound like the cans for me, I just have to save those pennies a bit longer.
