You can load metadata onto .WAV files. I use a program called "Tag&Rename" to enter the same info you would have on any .FLAC file. The whole argument of metadata is moot so the only real question is do you want your music uncompressed & lossless or compressed & lossless? May not hear a difference, but why risk it? SSD drives aren't that expensive compared to most people's last cable purchase.
Converting my CD Collection from .FLAC to .WAV
Lately I have begun converting my CD collection from .flac files to uncompressed .wav files. on the theory that doing away with a computing step in my transport and dac might improve playback sound. In some cases it does so quite unequivocally. Especially, there is a slight de-glaring of female vocals and horns. James Taylor's voice on October Road is now less shouty. Listening in general feels more relaxed and paced. SRV's guitar jangle is less rankling at times. Julian Bream's lute is less smacking.
Most of the websites from which I download files now offer only MP3 and.flac. In the old days they offered .wav too - understandble since download time and server space cost money.
What say you, knaves?
