Want to setup basic home audio system

Hmm, I have a "Nakamichi,, Ca-5", (Mint), just sittin there......
  And there is a Nak CD player as well.........
Hmm, some low ball offer...............Who know's??

"Oh look!, An amp!
"Pa-5"......hmm
(Very low ball),...................

Sounds like an invite, diripio!
Perhaps a pm is in your near future...

Wait a sec, HOW lowball??? 🤔

Oh boy.... I’ll give this a try.
1st get speakers that you have heard and like a lot. The Monitor are very good choice, if you like them. But buy something you really love....
2nd get a Bluetooth adapter, I have used and like this one, there are other choices for this, like any recommendation that I may give.

3rd would be an integrated amp, again many choices same as the speakers.
4th if you get powered speakers you can skip #3Note: some powered speakers and integrated amps have Bluetooth built in.
thus no need for adapter,.
there are choices out there that will satisfy your listening desires, you don’t need to go super expensive to get great sound. Only you will determine where it ends, it could be at the beginning.
Hope this helps. Happy shopping.
