Please explain how fractal theory applies and how the effect is audible. I do not disagree that most effects are scalable, but the degree of the effect is a meaningful consideration.Frankly speaking, I could not agree more with your post and link. I am an electrical guy, too and I understand and concur with what you are saying. Thing is that many people believe that everything that applies to the lGHz realm is irrelevant to audio. Fractal theory teaches that this is not the case, but everything is simply a product of scale. Skin effect, conductor gauge and geometry, insulation... all of this is relevant.
SMPS actually are more likely to produce more noise than is on the a.c. line and are usually incapable of passing line noise. I have tested this many times. Conventional power supplies are far more likely to pass line noise, but not to the degree many suggest. Again, I have tested that as well and rarely been able to find it, other than in the case of common mode noise. There are effects than can be measured in many line conditioning and filtering systems, but rarely does this noise pass through a power supply, IME. Again, tested this many times as a former tech over more than a couple of decades of work with everything form high end audio to video products with SMPSs.[/QUOTE]One of the things that you are overlooking is the effect that the AC sewer that we have coming into the house that supplies the system. Commercial power supplies are incapable of negating this crapola that rides on what 'should be' pristine 120VAC @ 60Hz. Stick a good scope in the wall and take a peek sometime. The power supply is the first place the bean counters go to suck $$$ out of manufacturing costs. SMPS that are poorly designed are really bad. How many wall warts do you have plugged into the wall? Bad juju.
WE appreciate the research, but I would like to see the actual data and analysis. Research is something I know a bit about. I have seen quite a bit of it and most does not support many of the assumptions and beliefs of the high end audio markets. I was once one of those believers until I learned just how much my own expectations and prior experience biased my listening. If the theory is not sufficient to explain what you can document, I would enjoy the challenge of trying to model the effects. The tools ARE available. You mentioned fractals earlier. Wavelet analysis can achieve precisely the kind of scalable analysis that will quantify such phenomena. With the high gain and high sampling rate acquisition devices available, there is no reason we cannot achieve models of any audible effect. Carver did this with very crude tools a couple of decades ago. We can do much better now with the computing power that is pervasive and the analytical tools that did not exist at the time.Nothing in the realm of audio is magic. It can all be explained by the math as a basis, but must be tempered by the reality that some things are simply unexplainable with the mathematic paradigm as it exists today. It is guys like me that are doing the research trying to provide that explanation. I don't just build them and sell them. I am seriously trying to find an explanation for the whys' and hows'. I think I am getting close to understanding and defining the impact of dielectrics on the equation in total. My mathematical skills are simply not up to snuff. That is why I am working with a young college grad who lives and breathes numbers. So does his significant other. She makes me feel stupid. The question is: why does the dielectric constant have the effect on the audio frequency band when common knowledge and current mathematical theory says that it should not? Dunno, but we are working on it.
Asking for your research and challenging your assumptions is not the same as calling you a crook. That simply is not what we are about here. If anyone does so, report it. It will stop. At the same time, some who share your views have suggested that those with other views are ignorant. We have been tolerant, but neither side will be allowed to make such suggestions and assumptions about others. Everyone will be expected to be respectful of the views of others.There is more to all of this than meets the eye....eerrrr.... ear. Not all of us are snake oil salesmen or crooks.
I was part of the high end industry for years, selling some pretty expensive products, and believed what I suggested to customers. I found over many years of testing and research that many of my beliefs were not well founded. I remain skeptical about much of the industry, but rarely do I consider those involved to be dishonest. Most believe in what they sell. That does not make what they believe necessarily accurate, nor does it make the differences they experience meaningful to other people.When it comes to buying power conditioners, power cables or speaker cables only buy from a seller that offers a 100% Moneyback Guarantee that is a no quibble guarantee. Do not let the fact that something is cryoed or has other special materials processing be an impediment. Those things should NEVER be a selling point, but merely one of the many tools that a manufacturer uses to get the end product. Way too many people are gullible and buy the buzzwords associated with a product. These are the same people that wil buy the new iPhone97 or whatever. Don't condemn the entire high end industry for the gullibility of the masses.
And you can say whatever you believe and relate your experience. As long as you show respect to others. Others, such as myself, can do the same, and we should challenge each other to make a good case for our perspective and we can discuss, debate, and disagree without attacking others. Just remember that challenging ideas is how we learn and share knowledge. That is very different than challenging someone's ethics.I'm just sayin'.
