Not sure about the vintage Mac piece but I bought a MC302 amp in 2019 and absolutely love it. I was using a Conrad-Johnson MF 2550 and the system sounded flat. Once I put the MC302 amp in the system, it was a night and day difference, so much so that this is my final amp. I would go with the MC402, it was current as of 3-4 years ago and will give you decades of pleasure. Good luck
