Perception is reality. I don‘t totally buy into that, especially with today‘s technology and its ability to affect our perception. But then magicians have been amazing and delighting us with their sleight of hand since the beginning of time. W. Shakespeare said, “My wife doth lie, but I believe her anyway.“ That‘s how I take technology. If I hear a difference between components or cables and I judge it to be worthwhile then I will buy it. Some people might need ABX testing to be sure they are spending their money wisely. I do not.
I notice in this video that the speaker concluded what he already knew through ABX testing. Interesting that he never mentioned which he like better- oversampling or no oversampling.
The days of high pressure salesmen in audio shops is over- or so I believe. Those types certainly existed in past decades pushing people to spend beyond their means convincing them that their speakers, amps, turntables were the best for the money. But nowadays it is possible in many cases to bring something home to try and return it if it doesn‘t meet expectations. If under no pressure, why the uncertainty that something sounds better or not?
If the shoe fits, wear it.
