Well that sounds convincing. I guess i could give it a try but i'm not really sure.
If i can return them I guess I have nothing to loose.
Do 320kbps files still sound good or not?
I don't have a DAC/amp at all but I do plan to buy one sometime so if my zune can run it till then it'd be great.
With wich DAPs can you run these cans?
High bitrate MP3's still sound great of course, I'm just saying that these really retrieve some fine details and nuances out of good lossless music that you would not otherwise hear with lesser headphones.
As for which DAPs could run it and which could not, it's all relative. For example my Sony walkman MP3 player could drive it to my ideal listening volume at 70% volume bar, and the dynamics are great. Of course there are some much more expensive audiophile DAPs out there but really it makes more sense to just get a portable amplifier if you're thinking of listening to these on-the-go.
As for DAC/amps, these will run great out of almost anything (I'm powering mine out of a FiiO E7 DAC/amp right now) and apparently scale well too, so you'll hear your DAC and/or amp's worth if you're driving these out of expensive ones.
