In the price range up to $15K you can get a excellent sounding digital system with CDT & DAC. The Pro-Ject audio CDT is an excellent source. There are a few reference DACs that will compete with your vinyl rig in that price range. The R2Rs DACs can be something special but just because there is an R2R does not mean anything if not if utilizing a proper design. In our comparisons the 6SN7 Sabre chip DAC sounds just as good as our DHT R2R DAC , it is a much simpler design but just has a different flavor to the sound.
Happy Listening.
