Here's the latest from Soundmagic - the HP150 - and here I think Soundmagic has combined the best qualities of the open-back HP200 with the best of the closed-back HP100 into the closed-back (but spacious) HP150. I can summarize my recommendation this way: If I were stuck somewhere with my music and player and just the HP150 for the rest of my life (a few years at least), I'd be very happy - it's a great musical sound.
