Bringing back the dead?

After reading the recent Stereophile's annual recommended components issue gave an idea for this thread. What are some of the best designed and produced audio products that is no longer in production? Apparently, I can't get this answer from reading new press. I am asking this question because I have only been in this hobby for about 10 years off and on. 10 years is not very long and I feel that I cannot not really appreciate this hobby without really understanding the past. Perhaps going forward, I can compare what's new to what I have been exposed to this past 10 years, but it would be nice to know what other products that was available before I started my audiophile journey. Is the best really yet to come or we have achieved the apex of hifi and we're all heading back down? Thanks for reading this thread and I look forward to reading your comments.
