Favorite obsolete formats.....

I live in an area where there are still some excellent broadcast quality FM stations. Listening to music on some of these stations through a quality anaolg tuner is an amazing experience.

Digital...I really miss it.

TDK SA 90s and if i wanted to splurge a Chromium Cassette tape.  $6 bucks a pop for 45 minutes of music each side.  I swear some of my greatest listening experiences were with those cassette tapes.

Sony Beta Max used for audio only. Phil Collins used these to mix Face Value.

You guys beat me to the punch with Elcaset.  I do remember listening to a really fabulous system (1980ish?) that had an Elcaset, it was actually excellent for the time. If memory serves it ran at double cassette speed, which would have been 3.25 ips.
Can't say I miss it, but it really knocked me back at the time.
