Vintage vs New

True vintage wine will kill anything new but you have to go way back to prior to 1965 and buy the impossibly expensive French wine of that era and when you do you will not want to drink anything else.

FIFY.

Depends what you mean by vintage. If ten years old is vintage then okay, there are some things from a decade ago that are still pretty good. Ten years to me is used, not vintage. Go back 30 years to the 1990's, now it gets a lot harder. Maybe a few things from the 1990's would still be considered good by today's standards. But the 90's is old, still not vintage.   

Vintage to me is the 1970's and earlier. Maybe stretch to the 80's, but that's about it. And no, there is no speaker from the 1970's that can hold a candle to DI. Nostalgia, and wishful thinking, notwithstanding.  

The situation with wire is even worse. Maybe someone so sure there was great wire back then can name me the 1970's era power cord they would put up against a circa 1990's Synergistic Research Master Coupler? This should be good...

Vintage for nostalgia and aesthetic style, modern for sound quality and everything else. There are no vintage speakers can hold a candle to Tekton Double Impacts, to name just one, and the same goes for everything else- especially wire. There simply was no good wire back then. No power cords, no interconnects, no speaker cables.

About the only thing vintage that can stand up to modern is turntables.
