Some preliminary thoughts from my headphone listening the past couple days. Two surprising observations, in particular. First (brace yourselves all ye prog snobs :), “Get Mine, Get Yours” by Christina Aguilera sounds brilliant on the Sony V6s. There’s a separation of instruments I’d never heard before, particularly in the bass, that doesn’t come through in the Grados. Second, “The Package” by A Perfect Circle sounds similarly brilliant on the Grados - the dynamic range is fantastic for a rock recording, and - this is the surprising part - the Grados are well able to reproduce the incredible bone-jarringly deep bass in the early part of the song. It’s not boomy bass; it’s tight and controlled, but still powerful.
On the other hand, Kind of Blue is hiss-and-crackle central. It almost sounds worse on these headphones than on my crappy speakers, if only because I can hear how poorly it’s recorded. And I have the relatively new remastered version, too. Finally, Gorecki’s 3rd (I know, I know, but I like it) is gorgeous on the Grados. These phones do wonderful things with female vocals.
