I always wanted good sound, but couldn't afford it until I graduated from college in 1977 and found a decent job. Just about my first purchase was my first "decent" stereo - a 60 Wpc Kenwood integrated amp, a pair of the New Large Advents, and a Dual turntable with Shure V15 cartridge.
When I got it home I hooked it up, and the first album I put on was Let It Bleed by the Stones. Gimme Shelter starts in very softly, with a nice clean guitar part - as the intro ends, there is a little guitar fill that swells to a feedback-drenched drone. That did it for me!
The other memory I have of the first couple of days with that new system was listening very late at night to Rod Stewart's Gasoline Alley. I had the volume down low, but it was very quiet, so I could hear all sorts of detail. During the soft ballad "Lady Day" (or something like that), there a couple of acoustic guitars playing, plus a very high and sweet slide guitar part. It was just like Rod, Ron Wood, and Martin Quittenden (spelling???) were there in the room.
