    Sound Science Corner Pub

    No problem. I gave the OP the benefit of the doubt to begin with but then he blew it up with claims of Woke Nazis and non-vaccinated Jewish Christians (or something), demonstrating the original post was just a troll prelude. G

    iPhone vs. Android via USB-C sound quality difference is huge

    “Sound Check” is Apple’s version of Replaygain, it can be found in Apple Music settings. There is also “Reduce Loud Audio” in the “Headphone Safety” section of the “Sounds & Haptics” section of main settings, which I believe does employ a limiter (compression). That is also a possibility. I...

    iPhone vs. Android via USB-C sound quality difference is huge

    As far as I’m aware, the iPhone doesn’t do any loudness compression, it just reduces the level of each track according to the loudness metadata but you say you have Sound Check switched off. And, although the moondrop DAC stores PEQ settings, it *might* use a default setting unless it is...

    iPhone vs. Android via USB-C sound quality difference is huge

    I don’t know, do you want loudness normalisation? You can turn it off if not. If it’s a profile type thing, that might be more difficult to solve if Apple doesn’t support the app but then that’s a user error effectively. G

    iPhone vs. Android via USB-C sound quality difference is huge

    It’s not easy to know what the iPhone is doing, what is being bypassed or what the moondrop phone is doing. For example, is the iPhone applying loudness normalisation (Sound Check) but the moondrop isn’t, is the moondrop sending some profile setting to the DAC that the iPhone isn’t, as bigshot...

    (Piezoelectric) Crystals, Hifi and Negative Ions...

    And that encapsulates the problem with nearly all your posts and as far as I recall, all of your threads! Firstly, you do not present any theories, if you did, then it would be up to science to invalidate them. What you actually present is unsupported claims/assertions or vague ideas that you...

    I would hope no one would take any of his posts seriously. I’m still not comfortable with the potentially dangerous BS but you’re the mod, so it’s your decision. G

    What didn’t you understand? No BS “advice” about things you clearly do not understand that are potentially dangerous (and can void your insurance)!! Really, what is wrong with you? @castleofargh you’re not going to let this stand are you? G

    Look, when you make stupid claims about audio because you don’t know anything about audio, that’s one thing and dumb audiophiles deserve to waste their time and money anyway, but when you start giving stupid/ignorant advice about something where the consequences could be injury or even death...

    Speed of Electricity in a Cable

    Electricity is “what is getting us shocked” and electricity is an electromagnetic field, not electrons! The electromagnetic field (in the video you posted) travelled at roughly 293,000,000 m/s while the electrons in a DC circuit travel at about 0.00002 m/s and in an AC circuit they don’t travel...

    Speed of Electricity in a Cable

    That’s just classic. Actually you’re still wrong, it’s the little audiophile pixies dancing around the electrons that get faster but they can’t be measured because only audiophile DACs can detect them. lol G

    So I post this: And in response you write this: Huh, that’s what your “logic” tells you is it? I think it’s way past time you had a serious look at your logic! G

    Speed of Electricity in a Cable

    Yep, as predicted you just dismiss the actual facts and instead stick to some nonsense theory which you’ve effectively admitted you just made up. Sure, Faraday, Maxwell, Heaviside, Einstein, Tesla and numerous others were all wrong because “what your logic tells you”. For logic to give valid...

    Speed of Electricity in a Cable

    You’re joking right? Are you really saying that you didn’t know the electricity in “your typical power grid in the city and in your home inside the walls” is AC? Why are you just making-up a nonsense theory when you don’t even know the most basic facts? It’s not a theory that the electricity in...

    Speed of Electricity in a Cable

    What has the quote above got to do with the quote below: What electron flow? OK, so you admit you just made-up that term “electron speed characteristic” but you’ve just replaced it with “electron flow speed” and still have not answered “what electron flow?”! G

    Speed of Electricity in a Cable

    Indeed, as you yourself are demonstrating but somehow you seem completely incapable of recognising it. If you’re not one of those with “false conceptions” then why don’t you answer the questions; what electron flow, what “electron speed characteristic” and what theory? At least answer the first...

    left ear resonance

    1st question: I don’t know. 2nd question: If I’ve understood the quote below, then the answer must be “something else”. If you turned around the headphones (IE. You also tried with the earphones on the opposite ears) and the resonance problem was still in your left ear then it cannot be a...

    Speed of Electricity in a Cable

    Huh, what electron flow? Unless you can actually demonstrate an electron flow in your typical power grid and in the walls of your home (and good luck with that!) then how is it slowed down and what is “electron speed characteristic” and what does it have to do with anything? What theory? You...

    It doesn’t matter what aspect of power you’re measuring, please provide the measurement of the effect it has, as you claimed! G

    Tidal vs Spotify

    1. But your method only measures the power at the end of the cable, it does NOT measure the “effect” of that, as you claimed! Please show the measurement that demonstrates an “effect” on the signal you’re outputting from the DAC. 2. If as you now say it is not “measured on the dac output” (or...

    Tidal vs Spotify

    Yes I did notice it was an opinion yet again, an opinion which demonstrates that what you hear (“the most difference in bass”) is incorrect/flawed because the most difference is actually in the treble! So, what is wrong with your hearing? Surely you’re not contradicting yourself again? Lol How...

    No, “reliably” means higher in that context and it was “proofable” by numerous professional scientists and engineers, in controlled environments with tens of thousands of subjects all over the world for around a century, ranging from very young children, to professional listeners, audio...

    My god, how many times? It’s go nothing to do with anyone disagreeing with me, it’s ALL about you spouting made up BS that disagrees with the facts/science. And, you don’t need me to try to make you look like anything, you’re doing that all on your own and exceptionally well! G

    @BS5711 To translate @Ghoostknight response in the terms of your post: Logical Conclusion = “I know that what I hear might not be real but I’m only subject to human audio illusions I know about, I’m not subject to human perceptual errors of any significance because after 6 years of listening to...
