What audio aspect are you knowledgeable in?

I am an absolute master of mediocrity over all technical aspects of sound recording and reproduction. The beauty of music tends to overwhelm me, so I guess I don't know much about music either, but I do like it.

Actually I am a civil engineer and electronics engineer, or was. I retired 3 tears ago but still keep interested. My first
audio was back in 1966 (Kreisler valve radio, multilayer drop records) before creeping to higher spec as money allowed.
Now I am proud and embarrassed to say my system is worth big money. Does that make it better than anyone else’s? It’s what we are happy listening to, what we are used to. No arguments. “My specifications are really no better than yours). I have a MS-91L TT and a J Allberts MC-1 cartridge. Nothing special but is sounds great. There are some other components that I think make my listening special, but please done think I am bragging. I’m not.
My employment enabled me to elevate to where I am.
Each and everyone of us will do the same. Maybe not to the extent it did, but in the end we are all looking for the best sound for the budget we have.

All the best all of you

In the 1990's when I was young and had a ton of energy and ambition, I did a lot of trial and error. I mean a lot of running back and forth to various audio salons. I happen to hit on a few combinations of really great sounding gear. Those impressions have stayed with me to this day. I'm much less focused on it all now as health issues and other matters have crowded in. I'm in the process of finishing my new  basement. Maybe that will restart my interest in it all.

Like Willie Nelson said “ I sing, but I’m not a singer, I play guitar, but I’m not a guitar player, what I am, is a song writer”.
