Hi bdp24,
You are a more pure music lover than I. I share my opinion of the sound quality of Close Ties only because it was recommended as a 2017 top pick and personally feel that sound quality does matter at that level.
I listened to it again (via Tidal’s MQA Master) and found the sound to vary greatly from track to track. On some tracks, the sound quality of Rodney’s vocal is very good, most not so much. Accompanying music is good throughout IMO.
My ideal is that sound quality provides a gateway to total immersion in the music, ie Eric Bibb’s newest release.
Peace.
Dave
