Overall the time span probably isn’t that tight. Perhaps the better way to phrase the question would have been “older phono stages”. My analog gear is from that era, and it might be cool to find a top notch piece from that time... see how it matches up. Unfortunately, many of the ARC pieces don’t have enough gain for a low MC. So my choices are find a cool piece MM/MC or MM with a SUT. That just adds another cable set etc. in an already challenging ground situation, another set of cables is something I would prefer to avoid. Currently I’m running a Moon 5.3 SS. Not at all unhappy with it. But then, I really haven’t heard many phono stages at this point. Never heard a tube stage though, and I’m thinking about giving one a shot. Thus the question...
