Very interesting thanks for sharing.

Thank you all for the insight. I learn more every day. To answer some of your questions... The X2's bass shouldn't be a problem for me since I like the bass-boosted sound of the MDR1A. Given your feedback I'll shortlist the X2, the HD598/599, and the AD700X. Quality-wise I use the "very high"...

I am a complete newb at this - wanted to get that out of the way in my first post. The reason I'm here is because I tested some Sennheisers HD6-something headphones at Frankfurt airport and was completely BLOWN AWAY by what you guys refer to as "soundstage." I can't remember the exact model...

Hi there, I'm Keith and I've used this site every time I needed a pair of headphones over the years so I thought might as well sign up :)
