I'm in search of a portable High Resolution player for the AUX IN on a Warwick BC20 Bass amp. Thus, I want to get a decent portable High Res player that can play WAV format. The music content will be from my DAW digital recordings in WAV format. And I'll be using it in other audio devices that have the AUX inputs. I considered, mp3, and it works fine with the Bass Amp. But my DAW exports in uncompressed files like WAV (no mp3), and it's a hassle to convert each file to mp3. And, I'd like to keep the higher resolution files for sampling or export on other audio devices. The features I seek in order: 1) WAV format (windows 7 OS). 2) Simple drag and drop files on to device or memory card. No proprietary software. 3) Battery life better than 10hrs. 4) Price under $200 USD. So far I've looked at Fiio x1 (2nd gen): which seems good. Anyone have suggestions for Samsung, Creative Labs, or other brands?
