Ron,

Good info. My interpretation of the quote above is that DD 5.1 includes ECC (error correction code). If this is true, AND the ECC it passed on when it sent across the coax/optical then I will buy into 'digital is digital' for DD 5.1.

However, the quote only adresses Dolby Ditital, what about PCM data from a CD. Remember, quotes from the Home Theater articles stated that they heard more of a difference in cables when listening to PCM streams from CDs. I wonder what DTS uses also? Are there any real PCM bit-heads out there that can give us the scoop.
