I feel same way even months after doing my review below - the GL1200 is a treat like no other headphone I ever heard - you need to try the gold ribbons too they make it that much better to have both- really an amazing head set

GL 1200 let you listen in the music (e.g., you are literally inside music performing event), and not just listen to the music (e.g., listening to a speaker). There are many headphones that widens the soundstage while changing the frequency to make the music very artificial or fake. GL 1200 is not.

For example, I never feel so real in Bill Evans live recording, especially the first 10 seconds in the announcement (1st track)

However, this live experience also has its nuisance. This excellent recording becomes unbearable because you can hear so clearly the breathing of the violin player, just like next to your ear!
