+1 for the idea of a sub-$1000 AVR that has streaming capabilities (i.e. Airplay for Apple Music). Having a few HDMI inputs would allow for growth (Blu-ray, Gaming console, Firestick, Apple TV, etc.) Even better with eArc for the TV. Heck, she might even enjoy local FM radio LOL. NYC has some great stations in various genres, and they are free. Not a knock against the Bluesound Powernode, but as you stated, she's not an audiophile. View her use cases through her eyes, not yours.
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.
