Sony's New SACD Player
I just read about Sony's new top-of-line SACD player in Twice magazine. It will have Firewire output for all channels. This will enable it to go directly into their new processor digitally. It will also have advanced copyright protection in addition to Watermarking. Other firewire enabled processors should follow.
