Some forty or more years ago, the average person who set out to buy a stereo system, typically ended up with a stereo receiver. Things were much simpler then; all you needed was a receiver, a turntable and a pair of speakers. As for ‘audio furniture’, milk crates were the order of the day. A pair of included patch cord interconnects and if you were somewhat sophisticated, a run of heavy gauge lamp cord and you were in business. You didn’t have to give any thought to power cords, because components had captive power cords.
Of course, there were serious hobbyists who bought separates and had furniture grade cabinets made to house their components and speakers. These folks constituted a very small minority of stereo buyers. Once the transistor era took hold, watts per channel was the order of the day; the bigger the box with more knobs and lights, the better.
