I got an integrated for $20.
My daughter's boyfriend works for a thrift store and he showed me this Sansui AU-9500 they had in the back. It weighs about 50 lbs, looked great and had some cool features, so I told him to get it for me, employe discount. He paid like $5. for it, I gave him $20. because I want him to turn me on to other stuff that might come in. Anyway, it's only rated at 50wpc, it has bass, midrange and treble controls, bass and treble filter switching as well as turnover frequencies for each. I hooked a cdp into the AUX and all the tone controls and switches work great. This piece originally sold for $550. in 1974-76. I hooked it up to a pair of Dynaudio Audience 60's just to see if everything worked and how it sounded. I was impressed, it was clear within it's limits, not much bass slam, the bass did improve a great deal with the loudness on. This amp may do better with a more efficient speaker. Plus when I hooked it up it wasn't in the most ideal listening situation. Oh, it also has 2 microphone inputs on the back. The big 1/4 inch type. I thought that was an interesting feature but back then reel-to-reel was still strong. It also has something called a 4-track adaptor, I suppose again something to do with reel-to-reel, and a input a switch for some type of Dolby NR. It also has preamp ins & outs. Fun huh?
