What was your first 'hi-end' system?

Wow, where do we draw the line? My first really "high-end" maybe was a McIntosh 5100 integrated amp and a pair of the original Bose 901 speakers. AR and Dual 1219 turntables, with Shure V15 and Stanton 681EE cartridegs, and a Sony 355 reel to reel tape deck. That system morphed quickly starting with McIntosh 2100 and C26, then second Mac 2100, then Thorens TD-125 with SME arm, an assortment of Shure, Stanton, and Ortofon cartridges. The Bose speakers were replaced with Bozak Concert Grands and I was off the deep end. All this "high end" thing started in 1970 for me. In the ensuing years a lot of stuff has come and gone.
