I will chime in only because no-one else has answered you.
I have both an Adcom DA600 and DA700.
I have used them with a Rotel transport (bought new back in??? 1999???), and a Sony SCD777ES.
The sound of the Sony as a transport totally destroyed the Rotel as transport.
I sold the Rotel, feeling a bit guilty as the transport was fine, but my realization of how inferior the Rotel was as a transport....
Anyway it all made me realize just how important the transport is to the sound.
(The Sony using it's own DAC sounded about the same as using the Adcom DA700)
I do like the Adcom DA700 (I bought it used a long time ago, and I had the DA600 from new wayyyy back when. I tried to sell the 600 but no-one wanted it)
I have NO experience with the Rotel unit you want to compare to the Adcom DAC... (and that with what transport?_
I assume you are buying them.. If you already own some of these things..??)'
