Moonlighting- working a side job.
Moonshining- running an illegal distillery.
Historically speaking, moonshining and moonlighting have indeed been synonymous at times. Homemade "corn squeezin's" was a very serious business. This treatise (which began as a chapter in the original Foxfire Book) explains many of the cultural and technical details of the enterprise. Excellent reading about (mostly) honorable folks trying to make an honest dollar. I'm not even going to touch the whole "Dukes of Hazzard" hooey. 😀

Regarding that headphone amp - wow... Two mystery tubes & sockets, some jacks, an Alps pot, a chassis and a resistor - for only $149/47,000 ? Where's my wallet? 😉

Interesting HDMI audio is digital but that plot shows a slow roll-off with frequency and a sudden drop at much less than 15kHz. The fakery at play here is so obvious who would be fooled?

Chasing links from the given link An Open Letter from Bill Low of AudioQuest | Stereophile.com I arrive at AudioQuest HDMI Cables | Real HD-Audio

There, the caption of the strange frequency response curve identifies the so-called test signal as "The spectra of the tune played in the AudioQuest promotional video on YouTube"

Since this appears to be based on a test signal with an unknown spectral content, it makes sense that the test results do not show anything like flat response.

No real excuse for this, because just about every modern PC has an HDMI output that you can program with the audio and video of your choosing to use as your source for testing.
 
On the Hifi guide to cables, one of the designers had high credentials

Bruce Brisson, MIT
Music Interface Technologies

I think he meant "Music Interfaith Technologies"

I was surprised at an easily audible difference between a friend's MIT Oracle and plain wire feeding his speakers.
I am guessing the expensive stuff compresses dynamic range enough to lower the difference between ambient and primary signal levels.
It isn't called accurate interface technologies.
And Martin's Oracles do result in a musical presentation.

One I was asked whether I use technology similar to MIT or not, I then googled some info on their technology, from what I could find, they seem to recreate some high Q resonance which was just the opposite of what I try to accomplish. Lots of people talk about different material, I do measure differences in the impedance. But I have also come across some measurements where I could not explain, which I feel I just need to find out what other measurement methods will work.
