I've been a satisfied user of the Sennheiser HD595 for years, but they've finally had enough of my abuse and called it quits. So I'm looking for the current equivalent, which seems to be the HD598. Is there something else I should consider when looking for open full-size headphones in the ~200...

Thanks for the help guys. Unfortunately Todd doesn't have any 595s left. He said he ran out about a week ago. And I just noticed Headroom has a special with the 555+bithead for 260 dollars. Maybe I'll go with that. I'm a sucker for sales.

I'm also trying to decide between the HD580 and the HD555. But I will be buying an amp. Probably the Headsave Classic. I was going to go with the HD595, but nobody has it in stock and I don't feel like waiting 3 more months to get new headphones. I also don't have any great source equpiment...
