If you hopped into your time machine and brought back audio gear- what would it be?


So you have a time machine and you could go back to the days when you first started to get interested in and knowledgable of good audio gear- and a genie grants you one audio wish- you can bring back any single component from those halcyon days- what are you coming back with?

I still have my Sansui 9090, pioneer TT, cassette deck and Teac reel. Even the kabuki sansui speakers. 
I think I’d set the time machine forward twenty years and bring back the best of whatever they have in the future. Hopefully digital will be dead by then. :)
