I play most of my music from a digital media player called an 'iBasso DX50'. I chose this product because it plays .flac files which is what I have been slowly replacing most of my mp3 library with. Even though the .flac format is said to be much superior to the mp3 when I listen to it I still feel like it's missing something compared to a CD. I usually listen in my car using the AUX jack on my CD player. My question is could the AUX cord / jack be the bottleneck to my music quality and if so does anyone have a solution in mind that would allow me to keep playing my iBasso? Thanks. One other thing. Even better than a .flac file is a .wav file because that's pretty much all a standard CD is playing anyway. One problem I've always had when I tried to rip music to .wav instead of .flac or .mp3 is that the .wav files don't always contain the meta data (artists, album, etc...), and sometimes the rips do contain the meta data. Can anyone explain this inconsistency and explain why a .wav files wouldn't get meta data ripped to it and what if anything can be done about it? Thanks.
