Could anyone comment on the actual battery life of the AK240? Does it achieve the rated ~14 hours?
My understanding is that, to achieve any manufactures claimed battery life, you would have to play lossy (mp3 and variants) or wav files, exclusively (minimal processing (CPU or the equivalent) because there is no compression). Flac files are compressed (think, audio .zip file that has to be unzipped on the fly) and DSD, massive amounts of data. The latter two require lots of processing (CPU) time which in turn means poor battery life. Everything is a compromise, less than stellar SQ (mp3), great battery life. Ultimate SQ, poor battery life.
