I don't think I'm gonna look for an IE80 replacement soon.
It must be a hell of an IEM to outperform IE80's sound and flexibility. An IE80 upgrade it gonna cost you much more cash then ~300$ .
If you can buy IE80's for 250$ (even used), GRAB THEM, as long as these sound good and all accessories are there.
If you find them too bassy , ISO_Mod them, if you want even more transparency, recable them.
So many options in a single package...Hard to beat. But an expensive one indeed. 400$ in my opinion is too much for an universal, as long as it's not titanium base, pure-silver cable, unique design, extreme comfort & isolation.
lol so they are growing on your even more I see Alex :P.
Waiting for my silver cable to come in the mail. I paid zeroshoe to repair my cable. He upgraded my connectors to the ones Toxic cable offers and also changed out my plug. Can't risk loosing my IEMs due to lose connectors. It happened 3 times :P.
