Probably my first pair of Quad loudspeakers, circa 1973. They changed how I perceived recorded music.
Also notable for its time was the ARC SP 3-a-1. I suspect it sounds quite dated now, but when it was new, there was really nothing like it (other than perhaps some highly modified or rare tube preamps, though in the day, I thought it bettered the Marantz 7).
I stuck with ARC electronics up through the SP-10 mk ii and Classic 60. I left the fold shortly thereafter.
I consider the Lamm ML2 SET amp to be a revelation. Though it was hardly the "first" breakthrough product I owned, it also changed my expectations of reproduced music.
I still own the ARC Dual 75a that I bought new shortly after the model was released. Most of the other equipment I owned in past decades is long gone, though I still have my original pair of Quads, as well as a pair of Crosby- modded 63s. And a pair of those old Decca ribbon tweeters, a pair of old Quad II amps, and.... :)
