I used Exact Audio Copy on a Dell laptop to copy my collection to both Flac and Wav formats onto an 4TB external solid state hard drive. The hard drive feeds a Bluesound 2I and an external Dac.
What I didn't expect was that I could hear a difference between Flac and Wav playback. I don't have "golden ears" but could still hear a difference. I prefer Wav, but that's just me.
