The two 5.1 waveforms (decoded DTS-MA and PCM) should be bit by bit identical, but slightly differ.
The two wav files came out bit identical for me using AudioMuxer. Also, processing the wav files with foobar 2000 DRM (Dynamic Range Meter) showed they both have the identical dynamic range and headroom. Here's the results from DRM:
foobar2000 1.1.7 / Dynamic Range Meter 1.1.1
