I'm so attracted to all this Marantz gear from the 70s!
I managed to never have any Marantz gear in my systems over the years, except for one piece that has perhaps 0.001% of the sex appeal of those classic Marantz receivers: for a couple of years in the 1990s, I owned a Marantz CD-67SE compact disc player.
I mainly remember two things about it - that it sounded very warm and musical (especially compared to the player it replaced, an early generation Technics mid-size player from the late 80s), and that I had mixed feelings when I sold it to a small independent stereo shop. What I don't remember is why I sold it, but I must have needed some cash at the time.
