Thanks for the info,
@Shanling. I'll do some more tests with the BT headphones if I get the chance. It only payed DSD files at that time.
I know DSD is most probably overkill on a DAP, but some of the SACD (re)masters are really, really good. I've got a few of Dead Can Dance, Dire Straits and Queen and they beat the CD's easily. Same for many vinyl rips. It's probably not the DSD or vinyl itself, but the mastering that's often way better than the CD counterpart. Little to no loudness wars there. A lot of times the CD is heavily compressed, because that's what sells and what sounds 'best' on the average, bad, consumer playback devices. Like mobile bluetooth speakers or Beats headphones.
As for space.. microSD's are very cheap at the moment, so I bought a 256GB one for use with my M0. Beause it plays DSD natively.. I do
I could convert it to PCM using all kinds of tricks and I would probably not hear the difference, not even when I would encode that to a high quality AAC file. But why should i? Actually, I should do 16-bit/44KHz FLAC for both gapless and EQ to work, haha.
