Any technology-driven product area is subject to changes and improvements over time. It's not like most of us are constantly upgrading furniture, carpeting, or large appliances. Computers and cars, yes, because they're technology-driven.
I have a pair of 16-year-old speakers (Mirage M5si) that still sound marvelous, but OTOH there have been many innovations in speaker technology in that time--folded ribbon tweeters, more neodymium magnets, new baffling and enclosure schemes, new cone materials (e.g., aluminum and ceramic), new surround materials and configurations, more coincident drivers (KEF, TAD), etc. There's also been more tube equipment and major sonic improvements in class D amps, more upconverting D/A converters, better digital timing, asynchronous USB, the rise of the digital music server, and on and on.
What have been the innovations in tables and chairs, or shirts, pants, and sport coats in that time?
