Off topic but there is a song that mentions Hasselblad:
I Am The Six O'clock News by Larry Norman (A cynical rock song from the Viet Nam War era.) I had never heard of Hasselblad at the time, and I still don't know anything about cameras or photography... I had an instamatic.

Next time you tell that story, make it about yourself.

(You can let-on that it's a joke later.)
I still don't. There's nothing wrong with the word (a lover of audio) and many (most?) people here consider themselves audiophiles. But for me it has negative connotations and most audiophiles are nuts!!! This is one of the FEW rational-scientific audio related resources. I consider myself a music lover and a lover of good sound.
I don't consider audio to be a "hobby", except when I occasionally build speakers or audio electronics. I consider it an "interest".
When I was younger I didn't have "audiophile money" and now that I have more money I'm still too economical (cheap) to qualify.

I also never thought I had golden ears because I couldn't hear the stuff the audiophile publications were talking about. I used to go to the stereo store and listen to good speakers but other equipment didn't sound that different to me (except for phono cartridges). And now I realize that the audiophiles and reviewers were mostly fooling themselves... But, I've always been a "picky listener". The "snap", "crackle", and "pop", from vinyl always annoyed me. Most people, including the audiophiles, didn't seem to be bothered by it. It was especially annoying when it was MY record and I knew when that nasty click was coming... I'd be waiting for the click instead of enjoying the music.
This "hobby" isn't as fun or interesting as it was in the analog days... The fact is that
most electronics are better than human hearing* (in proper blind listening tests).
Most of the digital formats too. Even high-bitrate MP3 copy is sometimes indistinguishable from a high-resolution original (in a proper blind listening test) or you might have to listen VERY carefully to hear a difference. MP3
IS lossy... Data is thrown-away to make a smaller file. But it's "smart" and it tries to throw-away details you can't hear... It's not nearly as bad as its reputation. When I got my 1st DVD player, I didn't know that Dolby Digital uses lossy compression. Some of my best sounding music (to me) I own is on concert DVDs with 5.1 channel surround. (There are lossless formats for Blu-Ray but I don't have exactly same thing in both formats so I can't compare.)
If you're not getting noise through AC power or brownouts, or some other problem,
it doesn't make any difference. All power supplies are filtered and most are voltage regulated.

What is a blind ABX test?.
Controlled Audio Blind Listening Tests
* With high gain preamps (phono preamps and microphone preamps) it's not that unusual to get audible noise (hum, hiss, or whine in the background). Sometimes you can get noise from a power amp too.
