Well - I can't speak for all companies but Audio Note actually hires people with degrees in engineering and they use some of the best measuring and test equipment in the audio industry. So they measure and test and pair match their speakers to very tight tolerances. Most speaker makers and amp makers do this and they all make choices - many of them make choices that they feel sound better even if it runs contrary to what ASR or Stereophile might say is best. Richard Vandersteen (oops another one I forgot to mention) is an example. But makers make choices - some will choose Omni-directional - some feel planars or ESLs are the best approaches - narrow baffle vs wide baffle VS Open baffle (oops forgot Pure Audio Project) - Horns - Line Arrays (oops forgot Scaena), single Driver speakers (oops forgot Voxativ), Sub Satellite - all of these makers have their reasons and all of them try to put out some technical reason for doing it their way and all of them give up something to get something.
The terms objectivist and subjectivist are arguably used incorrectly in absolute terms. Manufacturers measure the equipment and they make choices as to what they think sounds best. Objectivist audiophiles - focus on measured performance trying to get the output to equal what the input was - straight wire with gain in amplifiers - speakers that measure flat on and off-axis with low distortion with the widest frequency response etc. And most will adhere to the DBT approach that if you do not tell A from B to the .05 level of statistical significance then there is no difference beyond detecting any better than chance. Although it is interesting that Audio Note gear wins these shootouts as do amplifiers like the Sugden A21 against better measuring amps. Stereophile did a blind test with a Radford tube amp for $100 VS $3,000 SS amps - and even the designers of the SS amplifier picked the Radford as sounding the best.
It's important to try and remove bias from these evaluations because price/name/looks and for that matter measurements can bias you TOO an amplifier or Speaker or AWAY from a speaker. On another forum - a fellow liked a speaker - was going to buy it but then read a measurement that the pair matching wasn't very good so he crossed it off his list. But he didn't hear it - he just read it. Huh? Ken Kessler is a reviewer who always did pair-matching measurements and made a big deal of it - but he still bought Quad Electrostatic that were off by +/-5.9dB (pretty damn terrible) - this is the guy that cares the most about this measurement always going on about it then buys speakers that are pretty horrendous at that very measurement - because - umm he liked them - ESLs have a certain "something-something" that he likes. You can't say he doesn't know what he is buying. I think anyone who hears a Quad or Soundlab (damn did I forget these too) - they have a type of sound you're not getting from some NRC-approved Floyd E Toole-approved Revel. I am sure the Revel is "more right" in terms of whatever the measurements tell you but what is also true is SoundLab has a sound that boxes don't equal - what is better is then to your taste. How do you want that favourite artist presented - do you want it balls accurate - Black Coffee - or do you want it with Cream - or do you want it with both Cream and Sugar. Or do you want Tea?
Is it objectively wrong to ruin the Coffee with Cream? Is it Objectively Wrong to have your Steak cooked above rare? Is it objectively wrong to put BBQ sauce on Pork Ribs? You buy the system that plays your favourite music the way that pleases you. If that to you is all Benchmark and Topping - great - if it is Shindo and Analog Domain 8000 watt SS amplifiers - great - if it is AN or Kondo or Accuphase or whatever - that's great.
No one needs to be "saved" - there is a saying "Never feel sorry for anyone who owns a boat" - that saying came about because if you could afford a boat and the upkeep the boat requires - you have no money issues. And that is true for the guy I saw handing over an envelope to the Audio Note dealer here in Hong Kong with $12,000 USD to buy two AN Cables. I talked to him - he buys the best cables from all the companies - in cash. Is he buying a placebo? Maybe - but he's the guy with the boat - he doesn't need to be saved. If all these audio savers spent their time trying to convince the flat earthers and climate change deniers who are dumb as rocks - then they might put their time to good use. Saving some millionaires from spending too much on Tooobs and cables seems like a waste.
I absolutely agree with with You when it comes to letting everyone purchase whatever it is that rocks their boat. However, imho, the essence in subjectivism vs. objectivism disagreement lies elsewhere.
The goal for objectivist audiophile is quite unequivocal and the level of how well that goal is achieved by a piece of audio equipment can be fairly accurately measured. The only grey area in determining whether A is better than B comes mainly from how much one appreciates engineering excellence over one's hearing capability i.e. is A really better than B just because it measures better, even if the difference is not big enough to be detectable to humans.
The goal for subjectivist is purely personal satisfaction, The superiority of A over B is just a matter of personal taste, and here is the problem: The subjectivist camp - headed with the media and "influencers" living in symbiosis with the manufacturers - claims objective superiority of A over B without any objective proof. When their declarations of superiority without evidence is challenged, they revert to "personal subjective experience over measurements" argument.
Unfortunately there are lots of people who believe that the buying recommendations from subjectivists really mean objectively high quality, and make their purchases accordingly. At worst they are really swindled by snake oil salesmen. Trying to provide information to them so that they could avoid being taken for a ride is a worthwhile thing to do in my opinion.
