I've noticed that electric guitar stuff on my Radiohead doesn't sound like I thought it would on my M22's, but I had my hopes set very high. They are better than expected on everything else I've listened to, though.
Part of the problem may be the low volumes I've been listening to (Stupid apartment). I think it will sound more alive and exciting with higher volumes.
And don't get me wrong, I wouldn't trade them for anything, except M60's!
