1974 Gene Hackman movie, The Conversation.
He plays an investigator trailing a couple, recording what they say when they meet with a team of tech guys operating from the back of a bogus van using directional distance mics.
At night he plays sax and in one early scene he's in his appartment after a tough day, sitting on a stool playing along to a jazz record on his pretty impressive hifi.
I say that without knowing what it is, but it looks good and sounds even better. Early Tannoys maybe ??
