I would like to upgrade my cd payer, an EAD CD 1000 to a player that will play SACD and other digital sources. I am currently stuck with redbook but would like to be able to listen to high res downloads as well. I could use my cd as a transport and get a separate Dac...but I am not sure that will give me SACD play back. Is that accomplished at the Dac level or the transport or both? Thinking an Oppo 105 might be the ticket but video is not important to me at present.
