What did your system look like 30 years ago?

My system only showed up on a sonogram. 

VPI HW-19 Mklll, don't recall the low price MC cartridge
ARC SP 9 Mk. lll
ARC Classic 60
Thiel CS-3.5

Same system today, though I upgraded Audioquest and FMS wire to MIT 330 interconnects and MH 750 speaker wire. 
Also added a Grado Sonata MI cartridge
Why mess with a great synergy? 
Thanks to Steve Bauman wherever you are!

@millercarbon -- "Mathlexic? Or is it more of a logic thing?"

Was this confusing for you?  Something you didn't understand or agree with?

Optonica RP3636 turntable with Signet 5 cartridge
NAD 3020 
Polk Monitor7b
Discwasher brush and Zerostat

I still have the 45lb Optonica in its original box.  The pseudo granite plinth has survived a lot of moves.  Polks were in storage also until last month when they were gifted to a budding music lover.  Bought the entire system new in ‘78
