I wish I was a true audiophile like some of you guys so I could tell you what exactly is wrong.
I've had these puppies on for a half-hour now. They fit great. No sibilance issues, except for one track which is widely known to have been poorly mastered. The low-end is great, albeit slightly strong. However, being an se530/535 user for the past 6 years, it'll take some getting used to hearing a defined low-end.
The mid-range though, it's like someone is covering it with their hands. Something is holding it back. Not sure what to do. Any ideas?
