I am a mac user. I use either Max or XLD to convert flac to aiff (mac wav). Max is good when all songs are individual flac files. XLD is better then only 1 flac file with cue file. I use Tag to enter metadata for flac files that are not done or complete before converting. Hi-Res flac and dsf files I do not convert and use Decibel for playback(changes to correct resolution automatically). Reg resolution cds/flac I convert to aiff and use ITunes (remote access is better). I do have all my hi-res and dsf files on a separate external from reg res collection. Externals are inexpensive for 3T+ drives. I had a lot of albums already converted to aiff before I got Decibel so I continue to use ITunes for reg res music.
