Old Technology Migrating to New

I am an old (80 years) technology guy with a large CD library in a Sony Juke Box, a Pioneer tape deck (500+ tapes) [no 8-track, I skipped that fad] and some 1000 LPs and 78s played on a Technics turntable, all connected to a Marantz. In my last abode of a dozen years, I had three speaker systems around the house hard wired to the Marantz. Recently moved, the new layout has the electronics in a corner office. I do not want to run wires around this house. Is there a way I can use wireless technology to broadcast music from the Marantz to wireless speakers such as the Bluetooth speakers. I would like to listen to my Artie Shaw, Beethoven and Maria Callas elsewhere than in my office.
