HD 6XX, a Magni/Modi pair, and no real interest in hearing anyone else's opinion about what I should've gone with instead.

Haha fair enough. I ran an HD 6XX with a Jotunheim for a while, but ended up preferring a pair of JBL LSR305s with an SVS sub a lot more.

I think the main reasons were being able to experience the sub frequencies with my entire body (they're too big to fit in your ears!), and share the experience with my friends.
