[This is a long post and slightly off-topic. Bear with me please.]There's a similarity in being an audiophile. We're always chasing the last few percentage points of "perfection"!
Yes, well, you are right. I usually avoid discussions of audio because it can end up like talking about religion. Everyone has their own perspective so, like power, what is good to one person is only so-so to another. There is always another upgrade to do, and similarly, another truth to learn, which may or not actually be true despite what common knowledge and urban legend may say.
I offer some credentials. I have a significant academic background for understanding the math and physics of wave propagation and I've studied the psychoacoustics of music enough to take advantage of them in real-wold situations. I worked as a software engineer at Lexicon for 10 years. I developed the automatic room setup and room correction system for the MC12, a high-end surround sound pre-amp. For that project I had the opportunity to test a number of different rooms, both good and bad, including a newly build test room at JBL, and I wrote a software program to model the theoretical room behavior of speakers arbitrarily positioned in a room of arbitrary size. The consumer-audio test room at Lexicon had a drop-dead wonderful home theater to die for and I got play in it! I wrote software and effects for pro-musician gear. I wrote most of the diagnostics for the LARC II, the remote controller for the 960 which is or at least was the most ubiquitous high-end reverb and effects system in all high-end recording studios. (This list is too short. I could go on but I bore you.) I wrote a magazine column for two years on sound reinforcement for acoustic bands. My own band has been playing for 41 years and I've played guitar, mostly acoustic, for about 60. We have produced 2 vinyl discs, 10 (I think) CDs, and one DVD. I mixed about a third of them. I've had hearing tests for various reasons, spent most of my life with reduced HF hearing in one ear. A few years ago for medical reasons I needed ear surgery which included rebuilding the ear drum. So now that ear is much better. It's been a long and glorious audio trip.
So what's the point (besides just bragging), you ask. There is a connection, just wait. Way back when I worked at Lexicon I bought on employee discount the cheapest JBL surround system they offered. I augmented it with a pair of McIntosh bookshelf speakers I had purchased when I was a poor just-out-of-grad school employee somewhere. My sweetie and I no longer spend much time just listening to music for its own sake but we do watch DVDs and BlueRay discs, and now that we can't go anywhere and can't perform anywhere while covid-19 is raging, lots of streaming video. Trust me on this, if you want to hear absolutely gorgeous sound listen to a well mixed surround soundtrack on a decent but not necessarily expensive system. Every time a sense of envelopment grabs me by the throat I am astounded by how, um, enveloping it can be. I didn't spend much money by high-end audio standards but it sounds wonderful nevertheless.
The connection to our favorite Porsche is this: Spending a lot on audio is like going for the most horsepower. But there is a better way to nirvana. Get a few subtle details right, like handling, tires, balance, and then sit back and enjoy the ride. You can always find something else to upgrade but that's not where the happiness lies. Happiness lies within when all is harmony.
