i have an old Philco stereo, turntable,...the furniture stereo! still works...tubes in it sound incredible. got a technics out in my shop from about 82/83, still kicking. i just know its full of dirt and shit...
whilst not quite 70/80's circa, i've got a 90's audio receiver. i bought it from Circuit city after getting married. so the DISH tech had to show up at my house couple years ago... and make a few adjustments in the yard. anyway, she wanted to show off her "new technology" audio processer with bluetooth and emulated SS...blah. i thanked her kindly for her time and declined to have it demo'd, much less buy the damn thing (i've got a system here that works just fine). she looks at and says... i'll out pace that thing quickly. LOL... i fired mine up, she fired hers up and started running the volumes up...i had her squealing in no time. my old 90's shit SMOKED her new technology. it was glorious.
