What do/did you do for a living?


With the increasingly high priced items people own and are selling, I'm curious about the line of work people do or have done. I thought my $5k integrated was a massive investment, but seeing users searching for $100k speakers or $75k SET amplifiers has me curious about the varying lines of work people do to afford these items.

Aeronautical engineer working on aero-engines for over 40 years until I retired early in 2012. My love of audio got its real start in college, when one of my roommates brought his Quad ESLs to our shared apartment in London. As he was an electrical engineer, he built his own preamp, and I think he had a Rotel amplifier, and a Thorens turntable with SME arm. For the time it sounded amazing, and it infected me. So now I have a pair of Quad 2812s in my basement system, with an updated Sota Millenia turntable and Oppo 205 into a Nakamichi CA7 that I found on Audiogon. The amp is an Anthem A2. The upstairs AV system is KEF 207/2 and 202/2C fronts with B&W dipole surrounds, with Marantz 8805 prepro, an Oppo 105 and Anthem P5 multichannel amp. No Atmos yet, but there is no end in sight for my affliction, once I can accommodate an 86 inch TV.
I do systems engineering for deep space missions. I won’t be getting those $100,000 speakers without a lucky lottery ticket. Fortunately, there are a lot of good speakers available for under $5000, especially if you’re willing to buy used!
Backup Power Battery Sales for the past 20 years and still going.   Got in to car audio as a youth, then focused on home theater, and now finally two channel.   Love the hobby!!!
I trained as a singer and conductor of choirs and orchestras, and have spent about 2/3 of my career so far in church ministry and about 1/3 of my career in higher education as a music professor. Not being in a lucrative field has taught me the fun and adventure of improving my system as inexpensively as possible. The majority of my gear was purchased used (sometimes as much as 20 years old when I bought it), but it sounds wonderful to my ears.
