Just one more " vote" for newbies trying to sort it out, I know I won't change any minds for the vast majority. My background : EE degree, serious acoustic musician, well versed on subtle tonal nuances, very knowledgable about testing, stats, and multiple forms of bias and outcome incentive. Audiophile with much electronic hands on experience. Open to the fun of tinkering testing tweaking etc. Have tried many cables for fun.
No, cables if solid basic design and constructiion are highly unlikely to make an audible difference in any audio sysytem unless adding a filtering component. Ears like taste buds are highly influenced by expectation. At least wine snobs will do double blind tests and have a good laugh at unexpected results. And of course variations in wine chemistry really DO affect taste and smell, well in accordance with well defined laws of physics biology and chemistry. Audio cables of good basic design would necessitate violations of well established physics to make the differences discussed, which while not inconceivable, puts huge burden of proof i.e. hign degree of unbiased repeatability to be taken seriously. And THEN and only then a search for the exciting new laws of physics would begin. Scence denial is not a serious problem in enjoying a hobby. It IS a serious problem in many other aspects of life, health and ecology so it might be a shame if cable silliness is a gateway drug to "science is fake".
Just my take for newbies and the "still questioning" few.
I do sometimes choose to exploit tne very real Placebo effect in on health with a few dollars of a supplement with a hint of scientific underpinning, if there is very low likelihood of harm. (Immunology, psychology, microbiome etc. hugely complex systems with MUCH unresolved science, unlike 0-mhz electronic signal transmission) Obviously we all choose what amount to spend on audio placebo. But some of us will chose to challenge the science deniers in part because "I can say anything I want and shout you down to make a buck" isn't working out so well.
OK off to practice mandolin. Anyone want to discuss if a $30 pick is "worth it" vs. a .35 one?
