Do I have to get a CD player to sample DSD on my digital rig?

Just a note - you can use the Oppo BDP-105 (as well as other Blu-ray disc players) to rip SACDs if you want to archive them. I’ve done this myself with all my discs.

There are details here - https://hifihaven.org/index.php?threads/rip-sacd-with-a-blu-ray-player.3652/

Easy to misunderstand my comment, it does play the DSD layer, not the SACD

The SACD layer is the DSD layer.

Hmmmm  My Audiolab 6000CDT is not an SACD transport, so why does it play hybrid MoFi SACDs?

Hybrid SACDs have 2 layers. The DSD layer and a regular cd layer. Your Audiolab is reading and playing the cd layer, not the DSD layer.
