If you haven't noticed, there's a war raging in the world between rationality and blind superstition. Hardly any venue is immune these days.
In my opinion, this is partly why the audiophile online hobbyist world is largely male. Is it really a war between rationality and blind superstition? Us vs. them?
No one argues about car measurements and benchmarks. There are different ways to measure 0-60mph, and measurements may not correlate with preference even though ideals for most people, most of the time are consistent.
Everyone would argue against snake oil like tweaks that claim better fuel economy, better performance or better crash safety. If it is not measurable it isn’t real.
The claim that a seat is more comfortable, the steering is more engaging are all valid opinions which you can talk about steering ratio, adjustability, but ultimately subjective.
You have stuff like lighter forged rims. Probably not necessary unless you’re racing but it’s not snake oil if you like the look. Tinted windows. You lose clarity and transparency but it can be a worthwhile trade off for individual preferences. Giant rims on lower profile tires on SUVs, etc.
In audio, we would do a lot better to recognize measurements don’t lie, preferences are valid, and snake oil is universally bad. Less arguing. More cars and coffee.
