This sounds pretty much like what headphone audiophiles say.
> However, each driver + housing + amp setup is going to feel and sound slightly different. So it isn't really an objective improvement but they will likely be distinguishable from one another.
Brands like Sennheiser have a very different sound from Audio-Technica which have different sound than Campfire Audio etc etc. Which is "better" is very subjective but there is a difference between say a pair of Sennheiser HD650 and Beyerdynamic DT1990
