Headphoneus Supremus
I briefly listened to these in a Sony Style shop yesterday, and had a chance to compare them to the Z1000. The 1R sounded more open and laid-back to me, the Z1000 being more of a classical studio headphone with the typical upfront soundstage. Tonal balance difference was not as big as I expected, the Z1000 sounded more neutral to me but not by a huge margin. Last time I heard the Z1000 I didn't like the treble though so the 1R might actually be better with agressive material. I also have the CD900ST at home which are probably the clearest of the three, but the most bass-shy as well.
