yeah, but the big question is if you'd prefer the hd700 to the hd650, because not everyone have same "taste".
Some people even bashed the hd700 (search for the "peaks" and purrin related thread) . The best would be to listen them before buying them.
At least with the hd800 you have the warranty of a "technical achievement" (regardless of your enjoyment ).
ok than ill just have to try the 700 in comparison to my 650 and see.
