      It’s worth noting that gold plated connectors are not snake oil. Gold is a good conductor and doesn’t form a nonconductive oxide layer. That means it’s going to be more durable and won’t corrode together or apart like those old ass sheet metal tube sockets that all need to be cleaned.

        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.

          The Norquist-Shannon rate sampling theorem only asserts that for a given maximum frequency, you only need another other given maximum frequency of sampling to represent it.

          It does not say you can “perfectly” reproduce a signal. Only that you can reproduce all fourier components of the signal that are below half your sampling rate in frequency. It perfectly does that, yes.

          But the signals that only contain a finite number of frequencies all below a certain maximum frequency are abstractions used in signal theory classes for teaching that theorem, and in engineering to hit a “good enough” target, not a “perfect” target.

          Any frequencies bouncing around the room at over 22 kHz are lost at least to something using the 44 kHz sampling format.

          TL;DR: Norquist-Shannon lets you completely reproduce signals with finite information in them. But real life sound doesn’t have finite information in it.

            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.

            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.

              Nyquist, thank you.

              aren’t lost they fold into lower frequencies unless filtered out

              If by “fold into” you mean they add noise to and hence distort the readings on the lower frequencies, that’s correct. But that just takes it further from a perfect reproduction.

                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.

                  I don’t disagree that there’s noise in analog signals too, limiting their information capacity. But that’s coming from the limitations of our physical implementations’ quality, no?

                  Also I used quotes to refer to your words, not to throw shade at a term’s validity. I use quote marks to quote.

                  Doesn’t mean the same thing as just randomly surrounding it with quotes in normal use means.

        I agree, but with one caveat.

        Fully analog tube amps do definitely produce a warmer/richer sound with less complicated things to go wrong. Artists like them because they are reliable, generally user serviceable, (usually just need to replace bad/old tubes) and makes each recording sound relatively unique.

        The thing is, is that it really only works during production. Unless being cut direct to a master record, the sound will get saved in a digital format to produce the user-facing media, which can include digital-source vinyls.

        Those products marketed to audiophiles try to take the digitally recorded/archived products to “try” making it sound like the original.

        I remember buying some bits and pieces to setup my home theatre in a new house years ago, and the guy at the store tried to sell me a $100 TOSLINK cable. When I asked why a $12 cable was going for so much, he pointed out that it was the “premium” cable, to ensure the highest quality audio.

        I couldn’t stop laughing. Like their special cable scrubbed the photons before sending them or something.

        Yes. I have a love-hate relationship with those people, as someone that does unrelated analog electrical stuff. On the one hand, it’s kinda cool that somebody made these crazy parts (and found someone dumb enough to pay for it). On the other, no that’s not what my search was about.

          Well, there’s nothing wrong with using coconut oil for gum health. Some people even use it as a mouthwash because it was some antibacterial properties. It doesn’t replace the need for brushing your goddamn teeth, that’s an insane thing to think. But there is actually benefits to coconut oil for sensitive teeth (along with a change in diet), antibacterial properties, as well as the normal benefits of consuming coconut oil. It’s not all complete hogwash.

          meh. nutritional value is about the same, yeah, but that’s not the point of organic food. people who claim that eating an all organic diet makes you better are yahoos.

          The point of organic farming is that it is just all-around better for the planet, the soil, the organisms therein and less polluting.

            There is not conclusive evidence that organic food is better for the environment. Obviously there are facets of the environment impact that will be better than conventional agriculture, but there is a ~19% reduction in yield, and lower soil carbon in organic agriculture. A reduction in yield means more land must be cleared for agriculture, so the other facets of organic ag would need a to be substantially better than conventional to make up for it.

              I disagree. Just following your source to its conclusion, I think it’s safe to say OA (organic agriculture) is better all around:

              7.1 Pros • Lower emissions of CO 2 , N 2 O, and CH4 • Enhanced soil and water quality • Lower energy use per land area • Higher energy efficiency per land area 7.2 Cons • Lower soil profile SOC stocks [i.e. how much carbon is in the soil] • Lower crop yields • Higher land requirement • Lower energy production per land area

              Your conclusion that we’d have to clear more land for agriculture use if we all switched to OA seems flawed; e.g. here in Germany we use about 60% of agricultural land to raise livestock feed like corn etc (https://www.landwirtschaft.de/tier-und-pflanze/pflanze/was-waechst-auf-deutschlands-feldern). Seems to me like eating less meat and growing idk lentils or beans would not immediately lead to food insecurity.

              This is also what the FAO says: yes, OA leads to yield reduction when compared to conventional methods, but not to food scarcity and instead to healthier ecosystems (https://www.fao.org/organicag/oa-faq/oa-faq6/en/).

              (sry gotta go, more.later)

                Yeah, I definitely agree we’d be better off cutting land used for livestock. I guess it’s a slightly different story in Germany because any land you’re using for livestock (or livestock feed) is presumably land that could be used for human food. In America, much of the land used for cattle is ranch land not suitable for agriculture. We do still have massive amounts of land cultivating crops like corn and hay for cattle that is suitable for agriculture, though.

                Just going down that pro and con list, though, it really does seem unclear to me. OA releases less CO2, but it also stores less CO2 in the soil. Lower energy use/higher efficiency per land area is great, but what we really want is lowest energy use per X amount of food. The “enhanced soil and water quality” part is also debatable. this study shows a higher eutrophication potential from OA, so worse for water. It does seem to be dependent on the crop, and the impacts of beef are so insanely higher than plants, that it almost seems irrelevant how you farm crops.

                It’s somewhat like saying that a suburban block is better for the environment than a city block. It’s true, but only if you consider just that plot of land. A city block is way more efficient in terms of per person effect on the environment.

                I think the crux of the problem is that the original tenets of organic agriculture were set by some scientists a hundred years ago, but also people like Rudolph steiner who was an occultist. There’s still a mix of actual science and hippy pseudoscience mixed in to this day. For example, the focus on only “natural” pesticides means using compounds that have higher runoff, persistence in the soil, and broader impacts to insect life. I wish that there was more flexibility for OA standards to change to the best evidence that we have.

      Organic food is devinetively not snake oil. As you mentioned,Nutrition wise its exactly the same. However, the Environmental Impact is completely different. Organic farming is much better in terms of biodiversity, soil health. Since organic farming doesn’t include the use of pesticides it doesn’t kills everything else that would live on a field. Also, Theres always parts of the pesticides that stay in the crops and that you eat. I don’t know exactly how bad they are, but considering that(at least in Germany) Parkinson is an accepted work related illness for farmers its sure that they aren’t entirely safe for humans. However, we should take into consideration, that farmers get exposed to much higher doses of pesticides. If someone has some articles regarding this topic feel free to share.

        This is going to be different country to country, but organic farming can still use pesticides. I posted a link below as well, but organic farming is also not conclusively better for the environment. It has lower yields, and therefore requires more land. You have to balance the effects of converting more land into organic farmland versus the benefit of, for example, less fertilizer runoff.

        At the end of the day, “organic” is a marketing term, not a statement of health or ecological benefit. Most complaints about conventional agriculture (and GMOs) are actually complaints about industrialized agriculture as a whole.

        I wish there was a good, regulated term for food that was produced with the best known processes (and perhaps there is for specific foods), but “organic” is not it.

          I personally think, that the loss in efficiency is worth it, if you don’t have to use pesticides. This also becomes less relevant, when you take into consideration, that we have to move away from eating that much meat(which needs more land), so we have the land to compensate this loss in efficiency.
