Answer me this, Mr. Electronics Authority, why is skin effect even an issue when the signal is not the audio waveform, i.e., it’s not frequency dependent? Furthermore, nobody said double blind tests are unfair. What was said was double blind tests are no more meaningful than any other type of test. They can also be easily rigged, so in that sense you’re right.
Future of cables!

I know very little about cable technology & even less about quantum physics. I read this & immediately thought (10+yrs down the road) this would upend cable tech: efficiency, clarity, & probably a bunch of stuff I don’t even know about that goes into cable science.
So, say hello to your new 2030 $70k cables. I’m curious what other people think.

OK, getting back on topic for just a sec, here’s a crazy little trick you can try at home. The sound can be improved without changing cables .....and it’s free. 🤗 🔙 mahgister please note! Tie a square knot in any cable OR tie two adjacent cables together in a square knot. ♾ Also called a reef knot. The more cables that have square knots the better the sound. This includes all audio and non-audio cables and cords such as lamp cords, refrigerator cords, computer cords, etc. Courtesy of Peter Belt. Note I have not mentioned the importance of cable directionality once in this thread. |
You’re getting warmer. All pyroelectric crystals are also piezoelectric, but not all crystals that are piezoelectric are pyroelectric. The two effects are independent, I.e., they’re not (rpt not) linked. But since you reported good results with Himalayan salt lamps which are supposedly pyroelectric I fear you might be the victim of the placebo-electric effect. 😬 Pop quiz: How do tourmaline hair dryers work? |
You need to expand your Google search, grasshopper. Tourmaline is pyroelectric. “The first reference to the pyroelectric effect is found in writings by Theophrastus(c. 314 BC), who noted that lyngourion, tourmaline, could attract sawdust or bits of straw when heated.[9] Tourmaline’s properties were rediscovered in 1707 by Johann Georg Schmidt, who noted that the stone attracted only hot ashes, not cold ones.[10] In 1717 Louis Lemery noticed, as Schmidt had, that small scraps of non-conducting material were first attracted to tourmaline, but then repelled by it once they contacted the stone.[11] In 1747 Linnaeus first related the phenomenon to electricity (he called tourmaline Lapidem Electricum, "the electric stone"),[12]although this was not proven until 1756 by Franz Ulrich Theodor Aepinus.[13][citation needed] Research into pyroelectricity became more sophisticated in the 19th century. In 1824 Sir David Brewster gave the effect the name it has today.[14] Both William Thomson in 1878[15] and Woldemar Voigt in 1897[16] helped develop a theory for the processes behind pyroelectricity. Pierre Curie and his brother, Jacques Curie, studied pyroelectricity in the 1880s, leading to their discovery of some of the mechanisms behind piezoelectricity.[citation needed]” |
@mahgister You’re close, very close! 🤗 Actually, scientifically, it can be demonstrated that in the same controlled environments there are obvious differences between cables, sometimes more so than other times, due to the vagaries of the test system, the test person, weather, what have you. Even when the system has been profoundly controlled for RF, vibration, etc. in fact I suggest that it is in those overachiever type systems where cable differences are most profound. |
Of course this all brings us back to the unanswered questions, 1. Does external vibration affect the signal in wires and if so how? 2. Why do seemingly insert audio components like solid state amps benefit from being isolated from external vibration? 3. Is the audio signal In wires itself vibrational? |
It’s a moot point whether the “signal” travels inside the wire or outside the wire. Since the sound quality is directly related to the type and purity of metal as well as the size of the conductor, all things being equal, we need not concern ourselves with Poynting vectors, as cool as they are. Furthermore, the speed of the signal in wire is given for copper not for the dielectric material and it is a high percentage of the speed of light. We DO however have to concern ourselves with the induced magnetic field, the dielectric material, RF and other related issues as we’ve seen in many other threads ever since Gandhi was a Cub Scout. |
