Good point, I have a SOTA table, must be 20+ yrs old, an Aragon 4004 amp for the top, an even older Carver for the woofers on my speakers (8yrs old), a Sonic Frontiers pre, Luxman T117 tuner, all of these have close too or over 10yrs...I also agree that most significant advances are in digital, a good amp that is working correctly is still a good amp today.
I am not sure how long cables can last so I change them when possible, never using very old cables.
