First of all, I started a new thread before I saw this post, sorry about that.
My HD 555 headphones broke after 4 years of use, and I've decided to upgrade to actual audiophile equipment. My budget is about $600, not including shipping/tax. I am Canadian, so custom fees could be a problem.
I'm looking for headphones that are good for classic/progressive rock, metal and gaming. I don't listen to a lot of metal (mostly just Dream Theater, Metallica, Iron Maiden and Black Sabbath). I don't game competitively, so it's not super important that they're good for games, but it would be nice to have a pair that gives me a slight edge (the HD 555s seem good enough for games to me, if that helps).
I've been looking at the HD 600 (razordogdeals has them for $299 with a coupon) and the DT 990 600 ohm version ($300ish on razordogdeals with a coupon). I have little experience with hi-fi gear, and my city has nowhere I can demo some headphones, so I'd appreciate any input.
For your genre's the HD 650 or HiFiMan 400 seems to be very good fits. The HD 600 is a good can and very neutral--maybe too neutral for your intended uses. The DT 990 has a "V' shaped EQ with recessed mids.
