I would buy a small, digital receiver (10 wpc) with a world-class phono stage.
I would buy an adjustable, transparent subsonic filter. (Easier said than done.)
I would buy a modern 1 1/4" CONE tweeter that would play down to 1kHz without distortion. I'd want a polar response graph, too.
I would buy a loudspeaker kit with this alnico cone that included a suitable mid/bass driver and a Japanese saw. (It cuts on the pull and exerts considerable control.) I'd want thin-wall construction, too.
I'd buy nigh any push-pull, EL84 amp with published specs.
If I had the moolah, I'd jump on those modern incarnations of vintage loudspeaker technology. The Braun version of the original Quad comes to mind. And the SoloVox by Audiotorium 23 looks sublime.
We are entering a golden age of hifi in which the siren temptations of bandwidth are denied in favor of the allurements of the "girl next door." You'd think that a mag like Stereophile with a writer like Dudley, whose humanist background cracks from the page, would want to keep the vintage reviews.
