For me it was KLH 9s in a warehouse room in the building with a book store in Anniston, Alabama in 1973. My wife and I visited the store, and I mentioned to the owner that I was an audiophile, and I wished he sold LPs. He said no LPs, but he did have a killer stereo in the back room. The electrostats were powered by McIntosh. The souirce was a turntable. The sound was spell binding.
When was the first time that you heard great sounding speakers?
For me it was 1977 at Purchase Radio in Buffalo NY. My brother and I were putting together a system that we would share at our parents house. The song was Aja by Steely Dan on a pair of Altec 19's that blew my mind at the time, I'll never forget it. They were a little out of our price range at the time. The system ended up being a Sherwood receiver, KLH speakers, a Technics SL-1950 and a cassette deck that I can't remember the make. Great memory!
