“what type of CD drive is necessary/sufficient”
The one that is designed to rip CD’s. As suggested above, connect a Vault 2 via SPDIF (digital coax) cable into your Integrated DAC input. Once you finish ripping your CD’s sit back and enjoy your ripped CD’s or browse / listen thousands of songs through cloud based providers like Tidal or Qobuz.
If you want a primer on how to connect Vault to your network, search streaming in the forums. Lots of great info here.
