I have been fumbling around with it in the new firmware. I am trying to get low and middle mids a bit more separated, they sound a little congested at the moment (but in no way is the bass interfering with them). I am currently running the 12khz and 16khz bands at +2 (increase air between instruments, at +3 things sound too mechanical). I think I need to play with lowering the bass/mid-bass a little. I REALLY need bands between the 30hz/180hz and 1khz/4khz to make the proper adjustments, especially the latter. I am also unsure what to do with the 330hz and 600hz bands, as I never had them on Cowon players.
At the moment, the player sounds okay, but is lacking the imperfect euphonic sensibility my D2/B2/Zo combo had. I think taking a player with rolled off bass/small soundstage/slightly warm nature (D2), adding a miniature subwoofer/amp (Zo) and listening with ultra fast and sharp BA-based IEM's (B2) was my own personal magical formula and I am frustrating myself trying to duplicate it.
I have not bothered with the build-in amp since Day 1. I am either lining out to my UHA 6 Mk II, Magni or my car stereo. I was totally unimpressed with it and I believe in separating the amp/dac anyway. I am used to the Zo hissing at me all day, so I didn't notice hissing during my brief time using it.
