Jiggahwhat, please share with us what open-back headphone that you think isn't flawed, is more musical, and better than the HE-400 that is under $500? I'm looking for something with better bass, soundstage, clarity, and instrument separation. I am interested in trying them if you can point me in the right direction. LCD-2's retail for $1000 (too expensive for me), of course they are going to be better. D2000's are closed-back. From what I heard, those have recessed mids and can be fatiguing as well? Those and a few other headphones are going to have more bass impact because they are a closed-back design and not open.
