Saying that you are interested in Operatic and symphonic recordings and then offering up Muddy Waters Folk Singer as an ideal gives no indication at all as to what you really want in a classical recording. Recording a symphony or opera is an entirely different challenge.
Even with symphonic recordings there are all sorts of techniques. And what you prefer may not only be personal, but may depend upon your set-up and what it can accurately decode.
For example some of us like older recordings providing more of the room acoustic.* Some may prefer modern, so called "live," recordings with microphones closer to the instruments.** It’s time for you to listen to some, at random perhaps, and decide what works for you. Streaming allows you to do that very efficiently.
