Yeah, using gr10 directly with cowon d20, I found the vocal and acoustic really impressive already. very transparent and detailed in mid and tremble. However, a bit tiring for long time listening. dt770pro on the other hand is more comfortable, and detailed still. as a headphone, dt770pro provides better soundstage. Interestingly, though gr10 costs way more than dt770pro and not impressively better than 770, I still like it.
gonna have aune s1 pro soon which is more powerful (rumored that it beat most mid-level cd player). s1 will support clean line-out, therefore I'm considering if it's necessary to get an decent but affordable amp to go with it. But if these two cans won't improve much amped, maybe I can save the money then.
