Yea thats the impression I get as well reading up on it, the HD 700 benefiting from warmer dacs/amps. Anyway guess I'll wait a few more days before deciding.
One last question which might be a bit silly. Is it really worth it to get such high end headphones as HD 700 when mostly streaming 320 kbps music from spotify or is the source really important to benefit from them? Until now I've been using HD 595 for 4 years straight into the laptop.
A lot of people can't hear the difference between lossless and 320k MP3. Personally, if I'm buying an expensive setup, I'm going to use the best source files I can afford. Is there a difference? Dunno... but every little nuance adds up...
