No, you're still not grasping it. It isn't just "practically inaudible", it's exactly the same thing. Digital recordings(such as the CDs which we've had for almost 30 years)use the pulse code modulation(PCM)process. THD and MHD take the PCM bits and "squeeze" them into about half the space. Then when they're decoded("unsqueezed")what you have is exactly the same PCM bits that you got from the recording.

Enjoy the music, not the equipment.
