That is your OPINION. it is purely subjective. Do not try to pass it off as a fact. Some hear differences between cables, others don't. Since you're the latter, of course you will think others are just claiming to hear differences. Some people can't even hear the difference between sources and are happy with a mass market player. Cable and transport matching are not ludicrous at any budget IMO. The system is comprised of components. Each component contributes to the overall sound. Only when one takes this into account can they get the most out of their system.
The only facts are that your are wrong as far as any scientific measurements can tell, which eclipses a humans flawed perception. So, yes it is my opinion, but it is objective. You are working with magic as far as any facts are concerned, so don't pretend like I am the one talking BS. I also do not think people are claiming to hear differences because they are bad or evil. They are just human, and prone to errors. Maybe I came off as a little too rude in my first post, but it something I wasted a lot of money on when I really should have used that money on important pieces of equipment. I apologize if you took anything overly personal.
It IS ludicrous at any level, as it yields no difference. Like I suggest to others, throw your money at the homeless, or give to charity instead of perpetuating myths. If you have tons of money to fritter away, it is not so bad. If you are trying to stretch your budget to get the best sound possible, like I said, it is the worst possible advice.
I am 19, my hearing is as good as it is going to get. It is also most likely better than yours, assuming you are older.
I'll use cars as an analogy. Let's take a budget sports car such as a Camaro as an example. To get the most performance from that Camaro, you have to upgrade headers, intake, exhaust, etc... Each of those parts contributes to the overall performance. Example: intake adds 10hp. Can you upgrade only one of those parts and still get an increase in performance? Sure, but would you have as much performance as you would with everything upgraded? I highly doubt it. There is also the option of wasting money on a higher priced sports car. Let's say a corvette and leaving everything stock (which is basically what you're telling the OP to do). The fully upgraded Camaro will likely have more performance than the stock Corvette.
Yes, and that yields a measurable performance increase, however small, be it in horsepower, torque, handling, etc etc.
Now with that analogy said. Let's get back to audio. An interconnect would be somewhat equivalent to an intake. Where as an intake would contribute 10hp, the interconnect could contribute 10%. Now are you going to perceive that 10hp or 10% right off the bat? Some can and some can't. But you're more likely to notice the overall effect as more upgrades (headers, exhaust, etc...) or quality cables (power cord, digital cable) are added.
If your original argument/analogy made any sense when related to audio cables, this would be a logical conclusion, yes.
