Get your feet wet with Bluesound Node 2 and sign up with Qobuz to take advantage of highest resolution available (upto 24bit/192kHz). The DAC inside Rega CD player is a good one. I would use a good quality Coax cable between Node 2 and Rega.
You could buy Bluesound Vault 2 if you plan to rip your CD collection. Once you get used to streaming, you may not feel the need to spin CD’s. That’s how I started and now all of my CD’s are ripped and easily managed and accessible by app.
