Don't know about mini3, but PA2V2 isn't really a competitor of E11. It has very noticeable bass roll off when used with low impedance headphonce and not nearly as powerful as E11, slightly on the lush sounding side but not quite as good as cmoyBB. Either E11 or cmoyBB are both better choice than PA2V2. I would consider E6 a much closer competitor of PA2V2 and I personally prefer E6.
thanks for the reply.
i'd check the mini3 , but i think i'll get the E11. and maybe get a E6 for when i really need something portable
