I think the discussion has morphed into a discussion of why people are interested in gear, which is separate and distinct from whether we are objectivist or subjectivist I think. People can be ultra-obvectivist and have very limited interest in gear once they identify something that measures well, similarly people may have limited interest in listening to music or measurements etc but have a love of equipment.
I think it's an interesting discussion. To be clear I don't for a moment think any inorganic object has a soul (though I admit as AI advances that may very well change), but what these objects can do is stir something in our soul. This is really where I now sit in audio. My honest opinion is that for listening to music you just need a decent (which can be inexpensive) speakers or headphones, including wireless, a smartphone or other device and whatever is needed to drive your speakers or headphones (assuming they're passive). DACs and amplifiers were commoditized years ago, and if you make the effort to set speakers up and consider room factors you really don't need to spend that much on speakers. I just don't think DACs and amplifiers matter unless spectacularly badly designed, broken or inappropriately specified for the load. So why have an interest in audio?
Because equipment does stir something in my soul. I am an engineer myself, and I think that as with any profession or vocation, for many engineers it enters the soul and becomes a large part of what we are as human beings. When I see pictures of HMS Queen Elizabeth (the RN aircraft carrier), CGI of the Type 26 Frigates, pictures of various cruise ships, container ships, gas carriers etc something inside me moves. Partly it is personal pride (though I'd emphasise my own contributions to the designs were minor indeed) but really it is because familiarity with the designs and everything behind them (the people, intellectual investment and human effort etc) moves me and I see them as something more than just thousands of tonnes of steel. So it is with audio. I value good build quality, ergonomics, durability, industrial design and other things, I'll say again my Sony ES gear does not have a soul and it would be absurd to claim otherwise but it most definitely stirs my soul and gives me a pleasure which may be silly to others but is very real for me. It's not just audio, I have a passion for the crafting and precision of old mechanical and electro-mechanical things. It'd be bonkers to try and argue film is better than digital for photography but I look at digital cameras and smartphones as appliances whereas I love the Olympus OM-3, Contax RTS series, Nikon F, FM family, Topcon RE Super/Super D, Pentax LX etc. Watches are another example, my daily wear Huawei GT2 is better than my mechanical watches but if push came to shove I'd keep the mechanical watches.
So I see nothing wrong with having an interest in equipment, and see no contradiction in saying it really doesn't matter at the same time as having a passion for it.
