There’s a LOT of snake oil in the audio world. Especially home theater and home studio setups. I’m a professional audio technician, and some of the “audiophile” setups I have seen are just outright asinine.
Use balanced signal for runs over ~3 feet. Use the cheapest star-quad cable you can get, and the most basic $4 Neutrik connectors. Why? Because that album you’re using to test your “hi-fi” sound system was recorded using exactly that: Cheap ¢30/foot cable and basic Neutrik connectors.
It’s also what concert setups use. You think a concert with six combined miles of cabling is going to be paying $2000 per cable? Fuck no, they’re using the cheap shit (which was hand soldered in bulk at the warehouse workbench by their lowest paid shop tech), to run that million dollar audio system. Their money goes to the speakers, amps, and mixer; Not gold plated wire, robotic soldering, or triple insulated jackets. In double-blind tests, audiophiles can’t hear the difference between a $500 cable and a couple of plasti-dipped coat hangers twisted together.
The people who complain about digital audio also can’t tell the difference in double-blind tests. Because modern audio hardware is able to perfectly emulate old analog gear. Google the Nyquist–Shannon sampling theorem for a breakdown of how we can perfectly capture and recreate analog audio with digital equipment. Vacuum tubes were groundbreaking when they were first used. But they had a lot of issues, and have very little relevance in today’s systems. They’re prone to burning out, notoriously fragile, and can be emulated perfectly.
Also frequencies greater than half the sampling rate aren’t lost they fold into lower frequencies unless filtered out.
But if you think it’s easiser to capture those room acoustics with analog equipment the non linear amplification and distortion of any analog system is going to change the sound just add much if not more then a good digital system.
So yeah both lose or distort the signal but digital does it in avery predictable way that can be accounted for and it does have a frequency region that it captures precisely. Analog doesn’t.

It’s Nyquist–Shannon. Norquist is taxes.
Also frequencies greater than half the sampling rate aren’t lost they fold into lower frequencies unless filtered out.

Frequency folding is the term used in DSP no need for quotes. The Nyquist frequency is commonly referred to as the folding frequency.
And yes frequencies above the Nyquist folding frequency alias into lower frequencies. A simple low pass filter prevents this however.
Properly filtered digital sampling produced a more accurate reproduction of the frequency range with less distortion then an analog signal.
