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!

I've heard many mega dollar great systems over 35 years.  Probably Dynaudio Evidence Temptations and Wisdom Audio Adrenalines gave me my first taste of "next level" speakers over 20 years ago.

I'm documenting now many of the great systems I encounter via my Youtube channel.  Feel free to check out some of the latest I've heard...including the MBL Extremes and YG Sonia 2.3.

Martin Logan’s in the late 80’s at a local stereo shop. Can’t remember which ones but that kind of blew me away. Oddly enough over the last thirty years I’ve only owned one pair of ML’s for maybe a year or so. But that first impression early in my stereo psychosis was amazing.
I believe it was in 1979 when I visited a local hifi-shop with my brother and Dad, and they played the newly released Pink Floyd album 'The Wall' with "Another Brick In The Wall" (Part 2) on what was probably a pair of Yamaha FX-3 speakers (w/15" woofer), also newly released at that time. I was quite an exhilarating and physical experience that reverberated the whole room and our bodies. 
DCM Time Windows and I have no idea what year. Too long ago. I have to give a nod to @twoleftears for mentioning the Stereo Shoppe in Ann Arbor. Used to go there once in a while. Brings back memories of the hash bash and Shakey Jake on the Diag!
