When was the first time that you heard great sounding speakers?

First speakers that really grabbed me were a pair of Vandersteen Quattro's hooked up to an all BAT system at Audio Connection over 10 years ago. 

MBL was something pretty special for me about 7 years ago...

I can't remember the name of the shop in Pittsburgh but it was back in the early 80s, KEF 104/2s w/KUBE. I couldn't believe how good they sounded. As a kid I couldn't afford them but over the years I've always wanted a pair. I finally picked up a minty/reconditioned pair about two years ago, 35ish years from when I first heard them. I know there's better out there but for the $400ish I paid for these, they sure put a big smile on my face. I wish KEF would remake them in some sort of anniversary edition.

Maggie 3.6r's back in 2003 at The Listening Room in Baltimore. Had never heard sound as wide and spacious as that. Driven by acoustic research gear. Ended up buying both the Maggies and the ARC. 

2012-
Soundscape in Baltimore, MD near Roland Park.
The loudspeaker: Thiel Audio CS 2.4 - completely changed my life.

Happy Listening!
