There are some folks that cannot hear audio improvements that are very apparent to many of us. I don’t have an explanation for this. I guess, consider yourself lucky. You can enjoy music to a greater extent with a lessor investment.
A lot has to do with the enjoyment one gets from greater fidelity. I for one gain great enjoyment from small improvements in fidelity. I would much rather drive an older car and use lower quality TP in order to enjoy the lower noise floor and neutral balance of my AQ Hurricane than that of the very heavy copper power cord provided by the manufacturer. To me, the $2K is soooo obvious and worth the cost it is a no brainer.
This is why everyone should audition high end audio components in their system. Only invest in the ones that are worth it to you.
