The Earth was known to be flat for thousands of years. There are literally countless examples of known fact that are constantly being overturned with new knowledge.
So, if 2 cables were randomly blind tested, and several people noticed a difference every time… but they measured exactly the same… what then? BTW.. I’m not saying measurements are bad. I’m just saying that the ear is also a measurement device, and can’t be totally discounted.
The human ear is one of the most unreliable of our senses, especially when subjected to complex information. Much of what we hear subjectively is extensively post-processed by a bunch of diverse foci in our brains, to help us sort out a slew of simultaneous events that vibrate our ear drums across a range of frequencies and volumes, are positioned in a near infinite array of spatial locations, and are sprayed with a deluge of harmonics.
What we hear is biased by emotional states, memories of past events, anxiety, anticipation, distraction, age, positioning, anatomical differences, and most importantly, cognitive bias. Just as we find in taste testing, recent heard events can fatigue our ability to discern differences in subsequent events. Auditory stimuli involve a multitude of neurochemical reactions in synapses that take time to fully restore to baseline, and especially when we are listening intently with repeated exposures, these pathways may become overwhelmed—leading our brains to fill in suboptimal or corrupt data with what we expect to hear, at the great cost of accuracy. All of this has been elucidated in innumerable studies across a range of scientific disciplines.
Certain audio manufacturers handily exploit our ears’ susceptibility to bias to great profit—evidence of which can be found to a staggering degree over on that “other” forum. I joined this one with stubbornness and my head stuffed with decades of marketing apocrypha, and by eventually recognizing that I’m surrounded here by a wealth of extremely knowledgeable and experienced experts who were beholden to no one, and by opening my mind to listening for awhile, I’ve been rewarded with a knock out system that saved me a ton of cash. And the guidance I received came with no strings attached or self-serving motives.
Of course it’s your choice. If you’ve got a surfeit of disposable cash and love your system, by all means, enjoy your cables. Peace…
