Oh man, now you got me worried that I made the right suggestion :D
Anyways, read some more reviews as I only have 2 ears :)
I hope you will like them if you are about to buy them, however don't forget to upgrade your source further down the road, so you can enjoy them to their fullest.
And yes, I find the Q701s very detailed and combining that with a big soundstage is a part of the reason why I like them.
Don't worry, I've been reading reviews about the Q701 all over the Internet. I read nearly all of them on Head-Fi and some other sites :)
I won't forget about the source, but first I'd like to start with the headphones. I initially thought about the FiiO E10 just to get started (USB powered DAC with integrated amp, even if not very powerful for so little money seemed nice), but maybe I'll jump to something a bit better.
