WAV all the way for me, works on anything and gives the best sound, none of my players show artwork
originally i did everything at 320/aac, but aside from my Nokia N8, ,nothing else plays them
Wav is the most reliable format and best sounding, so for me its a no brainer, especially now large hard drives are so cheap
It doesn't sound any better than FLAC or ALAC. If it does, then the encoding is being done wrong.
