Hi. I've owned these headphones for a while now and although I have been impressed with them (they're the first "real" cans I have owned), I don't think they are operating at their full potential. For one thing, I just don't hear the incredible soundstage that people talk about in reference to them. It's ok, but much less than I expected. Also, I have gathered from the forums that "lossless" files are the only way to go for good music reproduction, but I can't hear any difference between 128MB mp3's and FLAC audio files played through my laptop.
The only other parameter seems to be my source. I am considering several DAC/headphone amps to see if that would improve things, including the Maverick Audio TubeMagic DAC D1/Xiangsheng DAC-01A, Audio-GD Sparrow or NFB-12, or even the NuForce Icon uDAC2. Are there other good DAC/amps in this price range to consider? How do these compare? Most importantly, how much difference could getting a DAC have on the sound quality I'm hearing from my AT's?
Thanks
