If you guys really want good advice on phones and equipment go to
www.head-fi.org imo. Careful of your wallet though, since I've been there the first time i've spent close to 3k on my setup.
I'm trying to not be tempted by the HD800s... Currently I have 650s with custom cable/ICs along with a Little Dot MK3 and an MHDT Havana dac (w/a Bendix tube). It's funny because as good it sounds right now I always want something better.
Damn you, Head-Fi.
