I'll respond in a different way. When I brought my first good system back in 1979, nothing too fancy, but it sounded great (Marantz receiver, Advent speakers, Pioneer turntable with Shure M95 cart.) - you would call it a low-end audiophile system back then. It cost around 1200.00 (I don't remember the exact price, but that's close). Then with inflation, a low-end but good sounding system today would be around $5K. And that would buy you a pretty good sounding system today. Not $400K good, but a system that would impress the average person, and even an audiophile.
But on he other hand, I had friends who had an Empire Turntable or an AR, a Shure V15 or Micro Acoustic, and maybe JBL 100 Speakers or Mirage. Which would have cost 4 times what Mine did and therefore would today put you into $20K. And of course you could go much higher then that.
