content: [ Specified attachment is not available ]After the9K Euros for a 1,25Mt speaker cable(standard copper wires coated with an infinite thin 85 microns of silver, the same audio response of a standard 50 Cents/meter copper wire), I discovered a mystique"cable burner" device."When cables are first put into use, their directionality is not securely established. However, once the Vidar begins running current through the cables, the trapped gases are dissipated and small impurities in the conductor’s metal begin to act like a diode, favoring current flow in a particular direction. By using extremely wide bandwidth signal as well as a range of both ultra-low and high frequency sweeps, the Vidar stresses the conductors, neutralizes charges, improves the way that signals pass through metal and ultrasonically conditions the surface of the conductors. It is these changes in both the conductor and insulation material that refines performance in audio cables."I will never cease to wonder how many silly things you can find in the audiophool market. Instead focusing on music they like and believing in their ears, most audiophools put their attention to technical specs without knowing not even a 1/100th of the physics involved, loosing the true meaning of music: emotions.I wonder what effectively do this 5 volts 3K "device" that a cheap function generator can't do to a cable (and with the same results: nothing).EDIT: added the image to a post instead linking to preserve it from any change on the source website

content: So let me understand: they sell and promote supreme quantum treated cables capable to transport every single detail of signal (sound) from source to the speakers without any loss. Huge materials, insulations, connectors, plating for a small bandwith of 20-20KHz. Even power cables should be silver quantum treated (while the house mains cabling, up to the power grid, is standard copper).Now this silly device to do "Burn-in" treatement to the cables.But in all this attention to details, they don't care or take in consideration that the original sound came out from a guitar or a synth or has been caught by a mic that use internally standard copper wire and has traveled to the mixer thru standard or "unquantum untreated quality" studio cables?Why the "end-user" cables should be treated while the source not?

There were other customers there one of whom eventually spoke to me and the conversation soon came to a point that it was all about the 'Sound'.With 40+ years in electronics and much in Studio Broadcast maintenance i took this 'believer' on a merry-go-round finishing with the classic that my ears are able to discern the mode by which the mains electricity operating any topend system has been generated, either by Hydro-turbine, Gas fired, Geo-thermal or Solar....

content: Quote from: vltr on October 22, 2017, 12:05:21 amno, it is because the components and resistor networks will be contaminated by the burning in of the previous cable, and thus to burn in a new cable you have to replace all those parts, so the new cable will not get an unwanted colouration from the bad effects of those parts that have been subjected to the previous cable "newness" and which have thus been subjected to a parametric change that renders them unusable to be used on the new cable.As well you will have to send it in for servicing every 20 cables or annually for a calibration and service, to ensure that all the internal cabling and connectors has not been contaminated by the burn in process, and that they will not cause any unwanted effects on the cables being burnt in. Calibration unfortunately is a long process, and might take a few months to accomplish correctly, so it is best to have 2 of the burn in units, so that you can have one in for calibration while using the other one.Calibration and service unfortunately, due to the specialised and arduous testing required, does cost a little more, and is only $5000 per unit, postage and shipping to and from sadly being the customers responsibility, along with insurance. Payment with request for service only, by bank draft, International letter of credit, bank guaranteed cheque or cash with device only, due to unforseen circumstances that have occurred before.

These are of course not from trusted sources but I don't think Qualcomm is going to correct anyone.Generally, anything that an engineer can think of to 'improve' quality won't cut it. It has to be expensive and unique, both of which are seen as signs it "must be good". This is why a lot of "audiophool products" are so basic. No complicated electronics, DSP, or acoustic design, but a basic cable WITH ALIGNED CRYSTALS. Or a very simple valve amp, with capacitors 'rescued' from the the iron curtain, and transformers, wound to receive the shumann resonance. Any actual 'technology'.. many will trust engineers, but add some unique mystery to it, and engineers know nothing - they're just sheeple or part of the conspiracy.

content: I don't think these scam artists make too much. This business is probably based on very low operational costs, and they celebrate every single order. I guess there is quite a competition because this kind of scam is so easy to set up, only a little bit of imagination and some social skills needed. Generally high moral of an average person I believe in, is the only limiting factor.Note that while it maylooklike they are actually selling the products in significant numbers (e.g., by claiming distributors, or actually having them distributed at physical stores, or having "used" units sold at Ebay, or posting "user experiences" on the Internet), that is just a part of the strategy to make them look like a "real player", most likely fabricated.There is alotmore immorality - and moneyz 4-5 orders of magnitude higher - going on in established, well respected large businesses, especially in the field of medicine, healthcare, food chain, attorneys of law, you name it. Even when it's really affecting the lives of millions of people in horrific ways, and the immoral (even criminal, but rarely goes to court) gain is measured in billions instead of tens of thousands, the risk of getting negative attention is extremely small (every now and then, one big company gets to be the "bad guy" for a while, but nothing actually ever happens); quite contrary to the audiophoolery scams, which "everyone" is eager to expose, because it's so simple, and not so scary to do.And it's not scary to expose cable con artists, because they are so freaking pathetic, and utterly meaningless.If you were to really try to change the world by exposing the really "bad things", you'd most likely get killed. So people look up to them, and respect them as model citizens. And they usually have billions of $.So these audiophoolery artists are like the least respected lowest level criminals everybody spit at.Also, money is not the most important thing in the world. Enjoy the fact how you have earned what you have; if you are unhappy with the number of monetary units in your hands, work ways to make more without compromising your moral. If you find it difficult, it's most likely because deep down, you are not so motivated on the money side of things; I consider this means you have healthy relationship with money, so I respect it. Keep doing good things, and it's quite likely the money will follow automatically. And when it happens, you'll have a clear conscience.

He had a side line in importing (mostly for personal use) very high grade cannabis resin, which goes some way to explaining his outré belief systems. So they aren't all crooks, some are merely credulous fools. I'd say the split is probably 50:50.

content: Quote from: Fungus on October 24, 2017, 02:52:22 pmAn EEVblog Kickstarter idea - all I ask is 5% of sales :-)Device XA device that "conditions and reconditions audio cables"(Pseudo)science behind it.Like any other item you own, cables and interconnects degrade over time, and the more "refined" and "specialized" the cable is, the faster it degrades as impurities and wear and tear take their toll, first making cables perform like low-end cables, and over time they will perform exactly like regular cables . Issues like work hardening (due to the flexing of the cables) and constant exposure to low frequencies signals, and the leaching of impurities from the insulator to the conductor. The initial stages of this process are wanted as "burning in" the cable, but it does not stop after the burn in period, and with extended use cables gradually "burn out".Very few people realize it, but similar to how the rubber surrounds that supports your speaker cones ages and change over time, degrading your system's performance, the cables and connectors age too.Unlike speaker aging which is an irreversible process,Device Xallows you to undo most of this damage, It sends a short, high current pulses down the cable - much higher voltage, current and frequencies than standard audio content . Connecting your cable toDevice Xand applying the current pulse causes any microscopic spots of resistance that have formed (for example, due to oxygen ingress into OFC wires) to microscopic defects of the heat up very quickly, and in tandem with the process of electromigration allows the connector and conductor to perform closer to "as new" condition.For older cables, you can think of it is much like an Auto Battery Desulfator, which uses pulses of electricity to restore aged lead acid battery to function, it doesn't make it "like new" but it definitely restores a significant level of performance.However, like the way human skin ages, cable damage in cumulative and cannot be completely rejuvenated, so to ensure that you maintain the sonic purity of your cables it is best to treat them with "Device X" at regular, monthly intervals, maintaining the cable's youth for as long as possible, for your listening pleasure.As an extra feature, because it controls the direction of the pulse, it can also repair any damage that may have been caused by accidentally using directional cables the wrong way around, it can also make standard 'bidirectional' cables perform like their higher value 'directional' cousins.Other featuresOh, it also has to charge from USB. That is a must. And Bluetooth - must have Bluetooth. Yes and Wifi to monitor the rejuvenation process with a HTML5 GUI, from anywhere on the planet.Business modelKickstarter for a limited edition run of 20 at at $1,999 each, and spend $300 on case aesthetics and cool looking sockets and $5 on a LM555 PCB and a $5 ESP32 for Wifi & Bluetooth for then we are onto a winner!

The most important aspect is creatively describing what supposed benefits it offers, and make sure you use gold plated connectors and the most exotic looking components you can find. The vast majority of devices like this are simply expensive placebos, and to that extent they do work.
