Mc is a big line to compare, but in general it's a step up, unless the distinctive but typically loose, warm and relatively average (in my opinion) vintage sound of the popular vintage Marantz receivers is what you like.
Unless the vintage Marantz is refurbished or upgraded with more modern parts, perhaps. But then, it is something other than what it was originally.
YEs the tuners in some of the better vintage Marantz receivers are quite nice, as were many tuners in the better receivers of the day.
I sold Marantz and many other popluar receivers back in their heyday. I was never a big fan of the Marantz sound, though I suspect that using the Marantz's with some more modern and higher efficiency speaker designs that have improved in many ways since then would help and could make for some decent combos by modern standards, at least for some kinds of music.
