I only buy used components, but will offer a slightly different perspective.
I have owned two different vintage Accuphase tuners, and they are outstanding. I currently also own an E-303x integrated amp, and, though it was manufactured in the '80s, have absolutely no incentive to replace it. Yes, I initially spent some additional money re-capping and tweaking it, but have no doubt that it can hold its own with, or even outperform many contemporary amps costing as much or more.
I have also heard high-end technicians marvel at the build-quality of older Accuphase components.
As for specific sound, that will, as always, depend on associated equipment, listening space, personal preferences, etc.
