There's vintage audio, then there's vintage audio. While seventies receivers seem all the rage, there are also many great antiques out there. Take a pair of Quad 57's and Quad II amps or Futterman OTL's from the fifties, with some simple mods or changes to them, and add a modern preamp and source, and you'll have a system that smokes a lot of modern-day equipment.
Man, I have to get my Crosby modified 57's out of the basement and get them working again.
