I spent an hour this afternoon comparing the PCM(751 doing the decoding) and bitstream (rest of gear decoding) for stereo music sources. I found that the 751 produced better results as PCM, than my Cyrus PreXpdQx or my Pioneer LX 53 a/v receiver. Using Cee Lo Green's track "Bright Lights Bigger City", the 751 produced the most natural sound; the kick drum especially sounded most "real". In comparison, the others sounded like drum machines.
For music, I had bought the 751 for its improvement as a transport, but it seems it is a better DAC than my Cyrus and the Pioneer.
