OP, others
When seeking a ’new to me’ SACD/CD Player, I found out about this DSD to PCM issue.
I started a similar discussion, some people mentioned specific models that output DSD there. It was mentioned somewhere, that using DSD in the production process was beneficial to the content even if converted to PCM output.
the quote below matched my experience listening to SACD: Quieter Noise Floor is about it

"Comparison with CD
In September 2007, the Audio Engineering Society published the results of a year-long trial, in which a range of subjects including professional recording engineers were asked to discern the difference between high-resolution audio sources (including SACD and DVD-Audio) and a compact disc audio (44.1 kHz/16 bit) conversion of the same source material under double-blind test conditions. Out of 554 trials, there were 276 correct answers, a 49.8% success rate corresponding almost exactly to the 50% that would have been expected by chance guessing alone.[38] When the level of the signal was elevated by 14 dB or more, the test subjects were able to detect the higher noise floor of the CD-quality loop easily."
