In the early 1990s I bought a Rotel RCD 855 compact disc player (retail price $399.99) which actually sounded pretty good on its own. It was equipped with a coaxial output which allowed the 855 to be used as a CD transport. Paul had recently introduced his P.S. Audio Digital Link dac (retail price $799.99), so I bought one to use with the 855.
That little dac rocked and was a noticeable improvement over the dac in the 855.
To this day I miss the 855/Digital Link combo. It had a really nice synergy and was affordable. 😊
