"Bridge Over Trouble Water" sounds artificial

During the pandemic I've been upgrading my sound system.  I used to enjoy Simon & Garfunkel, "Bridge Over Trouble Water".  With my upgraded equipment the hi resolution audio sounds very synthetic, with one track on top of another, not like real music at all.  The voices are doubled and violins just layered on top.  On my same system, I played a live concert of Andre Previn playing Gershwin's "Rhapsody in Blue".  It sounded real and beautiful, like a live performance.  Am I doing something wrong?
