One of the thoughts behind the Coen brothers making "Hail Caesar" was that the classics get remembered, but they made tons of bad movies back then also (that are now forgotten). I think it's easy to forget how much really bad equipment got made and sold as well!
Entry level audio is incredibly accessible now. I would say that even younger people recognize the difference between the basic entry level stuff of today and the even good level stuff of the past. I set up an employee with an NAD 712 and some Boston Acoustic CR6's and they love it and have commented on how much their friends love it also.
My main system is under 1K (well, excluding the DAC), but it's all made from 1967 to 1990 (or maybe 1995?)

Well, except for a WiiM Mini Streamer and a SMSL DAC, but that's my bridge to today for the old stuff.
