I understand what you mean, but just for the record, professional winetasters can pretty much guess which part of land in a given region a wine comes from in blind tests. So, i can tell you that there is a huge difference between a bottle labelled 1000$ and a 5$ one.

One telling indicator is that wine does practice blind tests a lot, and has blind test wine competitions that lead to prices, that help small wine producers get their brand recognized ( search for wine labelled with « medaille d’argent » or « medaille d’or » of any french wine contest and you won’t be disappointed) .

Audio equipments very much less so.
