Nick, the tests of course confirmed that there was no audible difference between the TrueHD, DTS-MA and uncompressed PCM samples. Since the TrueHD and DTS-MA compression is lossless, it gives the identical data that the uncompressed PCM does, so there's not even a theoretical difference and this is the expected result. What was interesting was that the higher rate(640Kb/s)DD track was also audibly indistinguishable despite the loss of data that still resulted from its compression.
