Why not go with a modern day receiver from Sony, Marantz, Yamaha. They all have built in streaming capability. They will all work for the tv you mentioned, and they would allow for her to expand if she wants. Add a turn table, Apple TV. Pick up a used center channel snd she can run 3-1 for tv and drop down to 2-1 for music.
Inexpensive streaming amplifier
My daughter, (not an audiophile), just moved into a small apartment in Brooklyn, and we want to buy her a streaming amp to connect to apple music, and her TV for movies. She already has a pair of (hand me down from my son) Wharfdale 10.1 (small bookshelf) speakers to sit on either side of the TV. Any suggestions? Thank you.
