Kinda related to the post above, but not to audio... Years back when I worked at a computer parts wholesale, they had a daughter company that built computers. The PATA cables were neatly folded and zipped to the case. Folded kinda like they're being delivered in bulk too. One day I had to help out tech support, I received a call from an electrical engineering student making a fuzz about these folds. At first I thought it was a prank, but he kept going too long at it and even dared me to follow up with his professor about it. Silly people.qirex posted:Because they're coming from a world where dumbass audiophile tweaks were accepted because of the "mystery" of analog audio. The people involved are either trying to sell/promote useless poo poo or they want to be lied to about it because the very thought that a 50 cent monoprice cable is just as good is orthogonal to their entire way of thinking.

Out of boredom, I was googling for my company, who produces cables. I stumbled onto posts of the head-fi forum. There's a lot of poo poo going on, but this one took the cake for now (I guess I should be proud, tho):quote:A little more listening in, in my bedroom system and main system. Definitely a nice cord! Not just for the money, but overall.

There's a PoE standard that allows up to 51W over all four pairs. And that's really pushing it in my opinion. Double of that? In DC? No way. And probably not a typo, since driving a TV is mentioned as scenario.

In the end, it's still just stupid poo poo. Just like these magical power cords, that oh so improve the sound. I like how its users completely disregard the wiring of their house and that, that leads from the main hub to their house.

Nah, I mean from the sound quality perspective. Audiophiles wouldn't care about anti-corrosive properties, because they're probably the firm belief that things like these wear out and have to be replaced every year.

Nah, but if someone was up for the effort, they could bullshit people on Head-Fi with that thing. Create some huge wire construct and pretend with fake RMAA graphs or spectrums that it works. An ideal lowpass filter with 10 blocks and 1.5m of wire.

Someone's selling an atomic clock as clock reference for your studio gear. "With the Atomic, I'd say there was a 20% improvement which for me is mind-blowing. The image was wider, more solid and the vocal appeared to project towards me!" "I noticed an immediate change in my soundspace the minute I heard the 10M plugged into my OCX-V. The stereo spread out, the edges were more clear, and the center seemed to come forward." (Quotes from industry professionals. I hope they're fake, because if not,  )http://www.vintageking.com/Antelope-Audio-Isochrone-10M

Vinyls are goddamn hilarious. Disregarding all the inaccuracies that are introduced while manufacturing them (like the master not being 100% clean when pressing the vinyl, density fluctuations in the vinyl platter), the playback is another tier of stupid. You're dealing with a gravity based groove sensing. It all depends on the flexibility of the needle and the pressure of the head, both influencing the inertia and thus the actual read out of the groove. The needle might not be falling into the hole by following the groove, but by using rises as a ramp. Then, because the needle might be jumping around like nuts, the low frequencies are attentuanted to poo poo while high frequencies are raised (see RIAA equalization, and the low frequencies, because they are what make the whole arm jump). That's why you need a preamp, if it's not built-in, to revert this. Considering that audiophiles seem to be all about the most accurate reproduction of somebody's works, vinyl is by definition the worst contemporary transport medium ever.KozmoNaut posted:If you generate a 20kHz perfectly analog sine wave, record it digitally in 44.1kHz 16bit CD-quality and then play both that and the original analog 20kHz source back into a good oscilloscope, you WILL NOT be able to tell the difference between the original analog-generated sine wave and the digital recording. There is NO DIFFERENCE. --edit: That said, sampling a 20khz sine wave at 44khz will result in a whacky digital sampling, that relies on the DAC doing its job 100% correctly (which they don't). Because you won't be capturing the peaks of each undulation. Combat Pretzel fucked around with this message at 11:58 on May 13, 2012 |

ShamrockShake posted:I'm having trouble actually parsing this sentence, but is that a site administrator banishing all talk of hard scientific methods? Do audiophiles have to resort to wildly attacking simple protocols to defend their fragile world? Amazing. I'm terribly happy that I'll never be an audiophile. And it doesn't even need blind tests, it just needs some common sense (which they obviously lack). I mean, I've posted about this before, but on Head-Fi there was a huge discussion about how super loving great sounding a power cord is, that's manufactured in my company. Jesus gently caress, I work in manufacturing and know the whole production process, and it shows that they have no loving clue about how their magic devices are actually manufactured. And how crude it actually is. I was tempted to take pictures of all machinery used for said product and try to tank the thread, just to see how they're going to explain these away. But that would get me into deep poo poo for industrial espionage. They're generally in denial, anyway, because another company is still in good faith with them, after this happened to one of their products:    quote:Yes, a poster on the Head-Fi forums had his fancy-pants power cable disemboweled by his cat, only to discover very little of value inside. Once ripped open, all he found was "a couple of bucks worth of 14 AWG PVC insulated bulk wire (VD's "LiniPur" conductors) and some ferrite powder, (VD's "5 dielectric layers") shoved into some heavy braided-wall PVC tubing to make it appear thick and meaty, and put together with dirt cheap connectors and DIY build quality."

You don't ground a metal chassis to the neutral lead. If you need grounding, you design your appliance around the assumption that there's a dedicated ground lead. If you don't, you make sure your circuitry is insulated from the chassis. Also, there are quite a few countries in the world that transport current in triple phase AC to homes (one phase acts as L1 and one as N, you connect the phases as you like to balance the load), and they're not third world countries. This is reason alone why this is insane design, because you're in constant danger of shorting two phases, or grounding one of these with your feet. Either way, this is a safety issue, and not really the point to begin with. Single phase AC doesn't have any sort of polarity in the sense of direction of constant flow, like DC current. Actual AC devices are designed with that in mind (essentially just electric motors). Virtually any other appliance works with DC, and a rectifier doesn't care where the main and neutral leads are. The diodes in the circuitry make sure of that. (And then again, there's that triple phase AC to one's home.) Combat Pretzel fucked around with this message at 22:23 on May 30, 2012 |
