Was that a slam at my speaker rig dude? I love my "turbo" bass ports and all the wicked lights dude! My chick digs it too man.
Seriously though I just listened to these Saturday at the Dallas meet. Plaidplatypus brought them. I listened out of his source (Shanling CDP) unamped with Michael Bubl'e and they sounded great. So of coarse I thought "I need to hear these amped", reached over and plugged them into my Darkvoice and bamm instant dogcrap! What's up with that? They're the only headphone I've encountered that sounded terrible out of the Darkvoice. And it wasn't just me Plaidplatypus thought so too. Back into the Shanling and immediate bliss again. What are you guys amping these with. Let's not even talk about the crazy good comfort factor.
Also guys, I'd consider the JVC's overall frequency balance in the ballpark of the HD650 w/Zu & L3000. Devout followers of bright headphones like K1000, Grados w/ bowls, even HD600 to some extent (well it's brighter than the HD650) - probably need not apply.
