Welcome!
FRM is referring you to his favorite circles.
Loudspeakers are the most important component for in-room listening. I prefer active monitors and own Buchardt A500SE's.
The room is the second most significant component for in-room listening. Should be not too small or squarish, well insulated, and dedicated to private listening. Try room EQ. Treatments can help (suggest GIK). Keep space between loudspeaker clear of everything.
CD quality streaming is the only source you'll need. Millions of albums available for a monthly fee. No storage, shipping, or handling of the media. Look into Qobuz or Tidal.
