But if that chap had realised that better sound quality was available at a twentieth of the price, would he have purchased those Wilsons.
I would take the fact that he did purchase them, as an indication that he did not believe in your vision of ´better sound quality at twentieth of the price´. He just purchased what he found desirable and superior for his personal enjoyment. People who spend such amount of money, usually had done a couple of listening comparisons, therefore having made a personal decision to do it. They don't buy such products randomly or without comparing or because it looks so cool. They want it. Maybe we should accept that.
Noticed one interesting aspect: People who bought WA speakers, although I might not agree with their personal ideal of sound characteristics, usually seem to be happy with them on the long run. They in most cases don't whine and complain publicly, about acoustic problems and dissatisfaction with sound quality, but enjoy music and buy another WA a decade or two later.
If you want to counsel people on which speaker delivers better sound quality than the ones they already own, my advice would be to start with individuals who already expressed dissatisfaction. In my experience, these are mainly people who purchased speakers after what I would call an uninformed process, you hear reasoning like ´bought them from the white van´, ´they were -60% off´, or ´I bought the ones winning the tests/recommended on a review site´, or ´they were having the best measurements´. These people need help, not typcical WA owners.
If someone finds magic in their system—whether it’s a modest setup or a flagship rig—I say cheers to that. We’re all chasing the same thing: connection through music.
I nominate this statement for ´wisest post of the month´. Cheers!
