Music is Art, Audio is Science. :)
If you only want the best sound for your money don’t let others make you doubt your own enjoyment or convince you to spend more than necessary for things you can’t hear or don’t need.
Sony MDR 1A.
Sony XBA N3.
Mee Audio M9B.

One nice "upgrade" silver cable for the Sony N3, but not a believer in cables changing sound. Impedance changes volume, but a cable doesn't have a "sound" - and anyone stating that a multi thousand dollar cable "improves" sound quality is sadly deluded. ;) And needs to do basic science classes again.
Aphex Twin to Zappa, and everything in between.
Ibanez bass, Marshall amps.
Pretty much reached total satisfaction.
It's a nice feeling.
