I would not so much concentrate on the technology used, but the sound of the components.
@eddnog (good username!) that advice from @ghdprentice as applied to amplifier Class (D vs. A/AB) is worth heeding. To this day some folks feel dismissive about Class D / switching amps and assume by default A/AB are superior; there is no sound support (pun!) for this generalization.
Selling something you like to make a newer but perhaps lateral move is not without risks. If you’re so satisfied as you suggest, perhaps also try some different source files than what Apple offers - if you vary the masters you access (I suppose many streaming services use the same edition(s)), you might find vocals effects you like more.
