I have an OPPO BDP-83 that I got used for $200 and use it with this device to play SACD and CD. The HDMI out of the OPPO delivers DSD or PCM. It sounds amazing with the Schitt Yggi+ and Benchmark DAC3B both via SPDIF. My frame of reference is the Sony SCD-1 SACD player, which died recently.

The other option for a transport is a cheap computer drive with the following streamer from ARIES S1 - AURALIC
This is a memory player so the quality of the transport should not matter one bit.
As with AURALiC’s Lightning file streaming, our unique CD playback feature uses the same advanced, jitter-reducing Memory Playback technology. CD data is first read, and compared several times for accuracy into the system cache before playing. The result is elimination of potentially induced jitter from the transport, canceling any negative effects from the quality of your chosen CD drive, potentially improving performance beyond what’s offered from competitors’ CD players.
