I'm looking to add to my headphone collection in the near future, and am specifically looking to add a truly neutral, analytical pair.
My current collection is limited to only the Vsonic GR07 and Audio Technica AD900, both of which I love and which complement each other very well. Here's what I'm looking for:
-Flat response. I absolutely hate "v-shaped" frequency response, or any amount of elevated bass. The AD900s are the limit on the amount of treble elevation that I will tolerate, and the GR07 the limit on the bass quantity.
-Good separation. A huge soundstage isn't necessary, but I can't stand congested sound and I'd like to get a good sense of where the various audio cues are coming from.
-Dry, fast sound with quick attack and decay and very aggressive texturing and detail retrieval. I'm not at all worried about listening fatigue. I don't want a textureless, liquid sound. Even the GR07s are almost too liquid for my tastes (but I still love them).
-Also, my only output device at the moment is a portable player, so keep that in mind.
-I don't have a lot of expendable cash right now, so cheaper is better.
I'm already anticipating that the responses are going to be overwhelmingly in favor of the ER4, which is what I'm planning on getting. I just want to see if there is anything else that might better suit my tastes.
What are your location and price range? Above a certain price level you are likely to be limited driving cans with an unamped portable.
You may also be limited by your music source files. What format are they?
