By the way, here are some stats on the non decoded vs decoded outputs

This is what Adobe Audition reports for the digitally rip (non-decoded) wave file:
Left Right
Min Sample Value: -32425 -32418
Max Sample Value: 32399 32416
Peak Amplitude: -.09 dB -.09 dB
Possibly Clipped: 0 0
DC Offset: 0 0
Minimum RMS Power: -89.95 dB -89.84 dB
Maximum RMS Power: -4.54 dB -5.32 dB
Average RMS Power: -17 dB -17.27 dB
Total RMS Power: -15.63 dB -15.85 dB
Actual Bit Depth: 16 Bits 16 Bits

Using RMS Window of 50 ms

By contrast, this is the statistics for the WMP decoded output:
Left Right
Min Sample Value: -16212.5 -16209
Max Sample Value: 16199.5 16208
Peak Amplitude: -6.11 dB -6.11 dB
Possibly Clipped: 0 0
DC Offset: 0 0
Minimum RMS Power: -95.57 dB -95.55 dB
Maximum RMS Power: -10.56 dB -11.34 dB
Average RMS Power: -23.03 dB -23.3 dB
Total RMS Power: -21.65 dB -21.88 dB
Actual Bit Depth: 24 Bits 24 Bits

Using RMS Window of 50 ms

As you can see, even for an HDCD disc that is NOT encoded with Peak Extend, the output of WMP is not identical to the non-decoded data.

In particular, if you zoom in on both files, you will find the low level information have been subtly altered, which is consistent with what the patent describes as "low level gain manipulation".

I think this is sufficient evidence to completely destroy your theory that there is no benefit or material difference to HDCD decoding on non-Peak Extend discs.

So, bottom line is HDCD decoding does make a difference, regardless of whether the discs are flagged with Peak Extend or not.
