Speakers: what are good specs for hi-res audio? Can you compare vintage v new based on specs?

What are considered baseline specs for “good” speakers (not top of the line but sold at specialty audio shops)? In terms of specs, I see Total Harmonic Distortion and frequency range as ones that would be more signficant if you’re listening to hi-res audio, but do people actually buy that way in practice? I’m also considering vintage speakers, could I just compare the specs to see which would be a better match for my listening (mostly hi-res FLAC files).

Money (you want to spend)
Sound (what you like)
Space (where you will use them)

Spec (irrelevant)
