Geek,
Don't get me wrong, I love listening to live music too.
I'd take it over listening to headphones anyday.
The best thing I've found to do is listen to the same music through different cans. The more you do that, the more you start to realize none of them sound like a live performance anyway. Each emphasizes different parts of the recording.
I've listened to a live performance that was recorded. Then listened to the same performance with headphones (hd600) and I liked it better with the headphones. Live performance = energy? Shrug. The best is playing an instrument IN the performance, but sadly I don't do that anymore
Now that I've successfully hijacked part of this thread, I'll give some of my observations.
The veil gives as much as it takes away. Your ear can only hear so many frequencies at once. I would
think that is why people tend to like neutral cans, they are "everything"...? But when you compare them to a pair of brighter headphones, suddenly you hear it differently and it is new. So the veil seems like it was a bad thing.
I'm guilty of this myself. I've switched headphones recently and decided my hd600s sounded more muddy. After listening a while to my new headphones, switch back to the hd600s and its not "muddy" just different.
Cheers.
