Same cause as the perceived differences between various $4000 interconnects.
There are differences one can measure and difference one can believe.
Some of the measured differences can be sensed, some not.
This is what led to the "all amps sound identical because they measure
identically" that killed hi-fi in the late 70s early 80.
What is missing is validation of the metrics. Perhaps they measure
identically because the measurements are flawed or miss something.
Perhaps the measurements do mean something, but not the whole thing.
How do you know?
The engineers of the world laughed at Mathematicians for 100s of years
because the Math guys played with imaginary numbers. It was much later
that the EE's decided that imaginary numbers, and complex numbers in
general, do a decent job of defining how electricity works. So the old
V = IR was replaced, sometimes.
What really happened is that the EE's found more places when "R" was not
resistance, but impedance.
One key thing I learned in graduate school is that it is pointless to
argue about beliefs.
