Cool, thanks. My 841 is a manufacture refurb, so I'm curious too if it should be passing the HDCD signal. Still sounds good, although definately a little lighter in the bass than normal with HDCD material. Conversely, it's bass is a little better with non HD stuff than my other Sony transport, so I think it is affecting just a little. Maybe? I have a big sub system, so it's probably a little more apparent than normaly would be.
