Right!
Here’s the thing: if you say that power cords or spikes or any one of a thousand useless accessories makes no difference, they will continue to ask the forum until they find one person who confirms their assumption and gives them an excuse to buy that useless cable or spike. The opinion of design engineers and professional musicians is of no interest to them. They care about being able to do something with their system, for listening is not enough fun.
