I see this written a lot. They're not really 'different' at all. There is a sense of rightness about them, for certain, and they're faultlessly detailed but totally unfatigueing - but then that's true of many headphones. I had HD800 with a very, very good headphone amp, and moved to Stax. They were comparable, with the Stax having slightly more and better bass to the HD800 (but not a major thing). The only real thing I'd add is that the Stax truly do make me forget about hifi. I couldn't give two hoots about climbing the ladder any more - my L700s with the SRM006t is 'destination hifi' enough for me.Don't forget to try out Stax Electrostatics. They are quite different and many prefer them to any dynamic system
The only thing you will find is that the build quality of them isn't quite as good as one would expect for the price. Maybe not the case for the higher-up SRM-009, but the L700s just don't feel like a £1k+ headphone. Lovely and comfy though!
