It is interesting you mentioned that and you may know this but the speaker you pictured is the Chronosonic XVX an ~$800k wonder. Most of the mechanical parts you see are part of the mechanical time alignment system. Of all the speaker designers in the world Dave Wilson was probably the most obsessed with the time domain, at least of the designers that could sell speakers in the price no object space. Years ago he designed a gantry system to physically move the drivers so they could be adjusted in the listening room so that the waves from all the drivers reached the listener's ears within 2 millionths of a second of each other. The Chronosonic XVX was the culmination of his life's works and his last project before stepping down and turning the company over to his son Daryl. So while I had never made the connection to mechanical watches it is apt both visual and in the very essence of what they do: giving humans the ability to manage time.

One thing to keep in mind is when you get your systems dialed in with your room you are 90% of the way there. Your system is really capable of extraordinarily good sound. However, I can't tell you not to lust after gear it is just part of the obsession.

I am not super deep into vinyl and analog but it is not a coincidence that turntables like speakers are the gear outside of room interaction that sees the biggest difference between the sound of the equipment. We have the electrical/electronic parts of a systems rather sorted and the difference between budget and stratospherically expensive is IMHO rather small. The gear that relies a lot on the mechanical world is very different. Turntables use movement to make electrical waves and the speakers uses electrical waves to make movement both are stunningly hard for 21st century engineers to approach something that could be considered perfect. I think both of them have a special draw for gear sluts. As I mentioned I am not deep into vinyl I shifted almost completely in 1984 when I bought my first CD player but the gear slut in me "forces" me to have a least a modest turntable and a small collection of vinyl to occasionally engage in the ritualistic act of playing a record.

As I mentioned there is a wealth of DIY acoustic information on the web with a ton on youtube. One good resource is https://www.gikacoustics.com/ they have a room acoustics visualizer, educational videos, and calculators. The make good acoustic gear but there is really no reason to buy it when it is so easy to build yourself and once you see that and look at the DIY costs the ready-made stuff starts to look ridiculously priced.
