Best streamer to start in computer audio

Trying to return to audiophile pursuits after having to quit hobby for a while.  What is the best intro to computer music servers and would I still need a separate preamp necessarily,?
Do you want to use an actual computer, or a an Audio Component that uses a specialized OS?
Lumin.  They have a broad range of streamers in every price range.  You can use the Lumin as a preamp too.
