I have a number of gramofon units (
https://gramofon.com) plugged into the Aux input of my various "classic" hifi set ups around the house. This means I can get the best of of both worlds - still playing my old vinyl, cassettes, minidiscs (!), etc, but can easily play anything I want, anywhere, via spotify.
So my aged relative Robert is a frequent visitor in my house
PS: for any of the rooms in the house that doesn't have a "hifi", I have one of these brilliant little TDK units,

which are also both mains and battery powered, and waterproof, so great for trips out too
