If you are at all interested in Grado's you might want to visit their website. Looks like they have done an across the board upgrade to their entire line of headphones, calling the new ones the 'E' series. I almost bought a GS1000i , but now I am glad I didn't. I feel sorry for anyone who did recently buy a new pair though. Hopefully all the hype isn't just that and they actually do sound better. I guess the impressions will start coming in shortly.
