I have an S7000 running into a DC-1 and the CD playback sound, while not being top-level, is very good. One thing that *REALLY* made a difference was getting a very good digital cable (I chose the Illumination D-60). I've not tried using a dedicated transport in lieu of the Sony so I can't tell you how well it does in comparison. However, considering the Sony and the fact that my DAC is a home theater unit, I'm very impressed by the sound. (Not that I'm not thinking of upgrading it soon, though... audiophilia sickness and all).
Sony S7000 used as CD player
I am in thje process of drastically upgrading my system, which will eventually go through a Theta Casa Blanca for sound and home theatre. I have been out of audio for many years and I am really confused about which way to go in the format wars.Until really nice units come out that can play it all, I was going to get a CDP. However, what about the option of using my Sony 7000 CD/DVD as a transport and using the digital output through a DAC. I was thinking of picking up a used Dodson and upgrading to 24/96 or a new Bel Canto. Thanks, David Shapiro
