"Gear shifters"....some are manual, but there's a lot of automatics on the lot...;)
Truth be told, I lack the disposible to run in the SOTA wheel of audiophilia, and have for most of my years past 30ish. Nor the leisure to spend discerning the details 'twixt A>Z anything, esp. since my hearing has admittedly required the application of 'onboard appliances' to render any profound 'imho' on any object of audio obsession worth your reading about...
I have learned what and how to make the items in my possesion recreate that which I enjoy listening to in the spaces I happen to have them in.
Some may 'snarf' and opin that "You'd be better off with a Dixie cup at the loose end of a string!" or some other not-so-pleasant response.
Note that I will not subject you to listening to it unless you stumble into my presence, or ask to be subjected to it. I do have a relative amount of regard for your inattention or basic civility.
Basically, it's a hobby pursued to enjoy music in a fashion that's done specifically to do just that, enjoying what's heard when I click the mouse, drop the needle, or engage the laser.
I only have to please myself...sometimes, even be impressed by my efforts to my own perhaps lackluster levels.
I suspect you're doing more or less the same. Enjoy. 👍, J
