I have had this LD player for a long time and I am finally getting to the point where my HT will be able to use high-end audio (beond stereo). My question for anyone who may know: does the optical digital connection handle AC-3 signals? I also have a CLD-59 which has the AC-3 RF (coax) output, the name being very descriptive with matching connections that can be found on many receivers. If the optical output is streaming the data to the receiver and the receiver is capable of decoding various audio formats, I would think that the optical connection can transfer AC-3. Unfortunately, it looks as if the optical connection was ahead of its time on this player and there is no description of its use in the manual.
