what are your top "audio bargins" in your system history?

@testrun  I remember my Spicas. They were quite excellent, but in time I went to Celestion SL600's, more than a little because the SL600's gave me near insane  3D. Anyway, when the SL600's eventually started going through one too many tweeter deaths, I ended up with NOLA Boxers. I've been happy ever since. True, they don't possess quite the 3D of the Celestions but their tone is a good deal more natural.

My Primaluna Integrated. Lovely tone. Fine imaging & 3D. As much slam as this classical music guy will ever require. Just spritz the volume and selector knobs with some Deoxit to quiet them down when they get glitchy. When a tube blows (which happens considerably less often than it happened in my previous tube amp adventures), you get hold of Upscale Audio and have them send you a new one.

I wonder if the SL600's I donated to the local thrift store ever found an appreciative home. I wonder, too, how long the tweeters lasted, or if the new owner even gave a damn.
