Just thinking that 40 - 45 years ago a 'hifi' would have been a turntable an amp or receiver and speakers. (Two or three mains. One or two ICs and some speaker cable.)
30 - 35 years ago, one would have had a music-centre (one mains and speaker wire) or a 'rack' system. More interconnects, but all very short and flexible and hidden away tidily unlike the inflexible 'hosepipes' that pass for cables today. (Some of these audiophile mains cables would not look out of place at a U2 gig or under the floor of a computer megaplex!)
They probably all assumed that by 2009 wires/cables would pretty much be obsolete or one computer style 'Bus' cable would do the lot.
Seems the average person here has more system cabling than an entire 1970s home required for all of it's electrical goods put together.
Even a TV back then only needed a coax and a mains lead. Now it needs SCART/HDMI/Coax/Optical/mains and probably RCA as well. The space saved by flat screens has almost been absorbed by cables! (And nowhere to rest a nice 1970s rubber-plant.)
Seems that only devices like ADM9s with wireless streaming or something like an Arcam Solo or naimuniti are able to get us back to the cable count of most of the 1960s/70s hifi's or even 1950s radiograms!
(Why does anything 'wireless' require lots of wires to fulfill it's wireless-ness?)
