Digital reproduction varies a LOT, depending on the gear, but mostly on whether you are streaming lossy or lossless. Bluetooth in particular can be really terrible (SBC basic BT), not bad (aptX), or quite good (aptX HD and LDAC0 -- though I’ve not heard aptX HD yet myself. In short, the codecs make a huge difference.
With the possible exception of aptX HD, Bluetooth does not equal the quality of streaming through WiFi or Ethernet. With the right equipment and source material, that can be as good as or better than an LP or CD played through a hard-wired connection.
