Should I re-rip?

Good suggestion. Think i’ll Do just that. Going to run A/B test with my current Bryston DAC and again when my Lampizator Amber II arrives. 

While there is no difference between flac and wav and I cannot hear a difference no matter how hard I try, I can tell you from my experience some flac files 24/96 and 24/192 give me listening fatigue. For the heck of it, I converted them to wave and that solved the problem for me. All DACs convert whatever format into PCM; I think the process of unpacking the flac files prior to that conversion has some kind of an effect.

If you want to convert to wave, dBpoweramp can do that directly to your flac files without having to re-rip. It even has a batch converter to do them all at once.

dBpoweramp also has a setting for "uncompressed" (not "0" compression) flac, which is basically, as I understand it, a wav file with great metadata. So, no need to worry about the effects of the unpacking. Sounds identical to wav/aiff to me.

Wow! If I can convert without having to re-rip, that would be marvelous. All your input is invaluable. I will play with dbPoweramp tomorrow. 

Ok, where in dBPoweramp is the batch converter to WAV?  Can’t find it.
