It's quite loud (-9dBLUFS, which I think is normal for a CD master). I was noticing on my system that the highs seemed rather harsh, perhaps distorted. My LUFS meter showed a True Peak level of +1dBFS. I turned the gain down a few dB in my DAW and the harshness went away and the master sounded good. As I understand it, some converters don't have headroom built in to accommodate waveforms that reconstruct with levels above 0dBFS, so they distort. If you're mixing through a DAC that does have the headroom, you might not hear distortion that other listeners hear. Also, compressed formats like mp3 can raise the True Peak level slightly. That's why I always leave a full 1dB of headroom.
