EE Electrical Engineer. Engineer is derived from the word ingenious. I understand you're being facetious cuz an audiophile would be a downgrade. And who doesn't like to tinker. :)
On a different note.
Sorry I plowed into you like that.:(
IME it's been very difficult to transform a 1960s living room into a serious, holographic 2-chan music listening space. I've failed somewhere, somehow. And now I'm too old - can't hear the nuances despite having good stuff.

And I am no audiophile nor claim to be. I just hope you don't recommend oxygen free speaker wire. :)
Hey! Get wit da program. Not all them "audiophiles" have Golden Ears. Those that DO have Golden Ears will want to spend big bux for Oxygen Free High Conductivity (OFHC) speaker wire with gold-plated terminals on the ends. If they have really deep pockets, they will buy speaker wire made from silver, instead of made from ordinary OFHC copper. And (just to avoid losing any charge carriers) the wire will be insulated with highly non-conductive and almost perfectly insulating Teflon sheathing.

Wien-bridge variable frequency audio oscillators were what got Hewlett-Packard started in business. The absolutely require that little tungsten light bulb (no LEDs need apply) to level the output amplitude. Of course, if you don't need a variable frequency oscillator, some corners may be cut or at least rounded off a little.

No, it is derived from the word enginour (“one who designs, constructs, or operates military works for attack or defense, etc.; machine designer”.

Later, it became associated with engines; specifically, coal-fired steam engines in factories and, yup, trains. As a parallel example, a mountaineer is someone who deals with mountains.

It is a response to what I saw on this and other forums back when I joined. It seemed like many of the answers to just about every question were either a 555 or a microcontroller. I started pushing back.

Don't get too comfortable with the devil you know. The devil you don't know can be a fun guy.

Well ... It's your fault!
I have read your solutions to complex electrical engineering
problems.
Ingenious was the first word that comes to mind! :rolleyes:

Well okay I'll get with the program I do like shiny things. Just like my ferret.

Awww! I LOVE them little ferret creatures. Had one living in our basement in Dayton, OH many years ago. It didn't make the trip to Florida when we moved here in December 2016. I like Angus cattle, too, cuz they tastes so gooood. We cooked up a pair of Angus filet migon steaks for dinner tonight. Ferrets, in general, would not be worth the effort required to prepare them for consumption as food, but they make interesting "pets" and are usually pretty good company.
