But the audio stages of two computers. The measurements I cited were

Hi Jim,
there are no analog audio stages involved. The trival distortion (lower
than -65dB) is probably the result of being passed through an
unnecessary sample rate converter with a small defect within the MS
Windows audio sub-system. The issue can be demonstrated without ever
leaving the digital domain.
