Hi,
in all the headphones that I have owned-listen to,
my favorite for sound quality are the Stax,
but the pair I've owned was more than 30 years ago,
so I would think that today they are even better sounding
and yes, bring some cash expensive, but I think worth.
Today, if I had the $$$ I would buy again the Stax
without any hesitation.
Of course you need a dedicated amplifier.
Stax or WOO Audio.
