Thanks for your opinions. Actually I might have gone slightly overboard with my criticism. I was listening to Spotify Premium/Graceland (Paul Simon) and everything was sounding so awful. I am now listening to Apple Lossless on iTunes and things seem to be much better. But imaging is still very poor. Going to get a pair of Senn HD700 next week and will do a comparison with that.
I'm assuming you are not using the stock Hifiman pleather earpads?
