On al-Khui and weakening of Qurra

[MuslimAnswers]

Salam Alaykum,

I have a question about the link: http://twelvershia.net/2013/12/04/quran-has-a-shia-chain-of-transmission/

where one of the Shia online commentators mentioned

If you want to be really nit-picky, Sayyid al-Khui [ra] in his book al-Bayan goes out of his way to weaken ALL of the Qurraa’ and their reciters as problematic in some way.

Is there any deeper discussion on this matter from our side, especially since it would be a fundamental attack on Islam itself? (In all honesty, with matters such as these I think it is best we consider such Shia scholars akin to Orientalists like Goldhizer, Watt, etc., and that we should answer their claims in that vein)

Of course we don't have an issue with the Qira'aat and these are accepted recitations.
