What are some of your best thrift store or "give-away" AUDIOPHILE WORTHY finds!

(Sorry about the exclamation point rather than a "question mark" in the title. Editing won’t let me correct it.)

I just had to share! I just recently found a set (2) of Transparent MusicWave Ultra cables at a thrift store. I paid $60.00 for the set. I put them on a pair of KEF 107’s, which I found at another thrift store 2 weeks later, for $300 in perfect condition. WOE! KUSC radio and my CD collection have come fully ALIVE!
