@randyhat - understood and your advice is sound (no pun intended)
but wait!....

Using the source I found of Rebecca Pidgeon Spanish Harlem (thank you for that recommendation, and which windows reports a bit rate of 2967kbps and the Yggy LEDs indicate 48 and x2, so that is hi-rez), I have listened to random sequences of about 15 seconds or so, and low and behold, I may (I'd like to try this blind, unable to do so at the moment) have "found the difference"! Mind you, all I need/want is some iota of evidence that there is an "improvement". But what I've discovered may be more than an iota, and instead just my own increased understanding as to what to listen for.
Within the track, from time segment 1:55 remaining to 1:45 remaining (albeit 10 seconds), there is bass, violin, and a maracas. Through the Yggy, the bass is definitely more pronounced, more "authentic" sounding, and it vibrates or "lingers on" just a hair longer than when played via the Oppo. The violin too appears a tad bit more authentic; and that is fine, if in fact it is a more accurate reproduction. I'm still "testing", but I *think* I'm beginning to hear a quality difference.
Again, I appreciate the test track recommendation.
It was also suggested by a friend of mine to specifically listen for "cymbal decay". I am able to download samples here https://freesound.org/, and will listen to that too.
