My guess is that we are in a global climate of subjectivity. What one believes is just as valid as the contrary belief. Some people believe killing maidens is desirable under specific circumstances. While other people believe it is ALWAYS wrong to do so, regardless. A dangerous state of affairs...where the prevailing version might depend on who has more power over those circumstances. Dangerous, and crazy. What is the absolute measure of "correctness"? Is one's stance better than any other? Absolute subjectivity is dangerous. And I can't even imagine a reply to this consideration.
Of course, I agree on that statement. And beliefs are just that, beliefs.
I prefer to buy products based on proof though and from company who underpin their product marketing with solid science in their development process.
We can talk about interconnects and see why they are different from a scientific standpoint and therefore might work different, capacitance is one factor for example.
However, all these snake oil products never mention data collected during the development of the product. They always have a vague claim like soundstage, resolution etc. Nothing of this is objective, nothing can be proven, nothing can be argued from a scientific point of view. It's just that, claims and clever marketing. And they exist to lift money out of people's pockets. For that though, I kinda have to laugh as they provide amusement for their blatant charlatan approach to business, more front then Brighton!
And you know what, it's exactly the same type of brainwashing that kills music and individuality.
