Need help with a Stereophile article Reply #25 – 2004-08-05 04:37:02 QuoteIf the goal is to test modulation cable worth 1000 $ per meter, it rules out the use of the ABX box, unless all its component are themselves of much higher quality that 1000 $/m cable, in order for it to be transparent compared to the tested cable (or plugs, or other devices).Certainly, assuming the measures of "quality" are in some way individually quantifiable with or without the use of an ABX-like system. Of course, I would be quite interested to discover interconnect that is indeed "worth 1000 $ per meter" rather than interconnect that is merely priced at that point It seems to me that it would be well within the realm of possibility to build such a box using individual components that bench tested as perfectly as possible (in terms of electrical characteristics/tolerances), and then test the assembled result, modifying it if necessary to achieve the absolute best results.QuoteTesting an expensive cable, we are testing the hypothesis that normal cables and interconnects, like an ABX box, have an effect on the sound.As long as the hypothesis is falsifiable, of course!QuoteSo why does a reputable company like DAL engage in the design and manufacture of audiophile cables? The answer is simple: since significant measurable differences do exist and because well-known and understood transmission line theory defines optimum relationships between such parameters as cable impedance and the impedance of the load (loudspeaker), the capacitance of an interconnect and the input impedance of the following stage, why not design cables that at least satisfy what theory has to teach? And, since transmission line theory is universally applied, quite successfully, in the design of cables intended for TV, microwave, telephone, and other critical applications requiring peak performance, etc., why not use it in designing cables intended for critical audiophile applications? Hmmm! To say, as some do, that there are factors involved that competent engineers and scientists have yet to identify is utter nonsense and a cover-up for what should be called pure snake oil and buzzard salve - in short, pure fraud. If any cable manufacturer, writer, technician, etc. can identify such an audible design parameter that cannot be measured using available lab equipment or be described by known theory, I can guarantee a nomination for a Nobel Prize.The bolded section should be read and reread by every subjectivist "audiophile", five times daily. Mr. Dunlavy is absolutely not joking about the Nobel prize. Last Edit: 2004-08-05 04:38:33 by Audible!
