Oh, come on, forget ceramic or mkp and just follow the example of all the Chinese "audiophiles" designers : put as many wima mkt caps near your opamps as you can.
 
But they have to be red for the magic to work.

 
 
 
Am I kidding ? I ? Never....

He's making fun of designs for audiofools.  In other words, "ooh, MKP/MKT, let's put them everywhere, it's so boutique".  The "proper" engineering design will use the appropriate caps necessary, taking into account the function the capacitor is supposed to play in that particular position, and why.

I have a one question, can you have a look at the ad797 on the board:
 

 
?
 
I have bought balanced card based on 4 AD797 for my MA9 and... I can hear hiss (ground noise!) in my IEMs (JH16),
 
I am sure that genuine AD797 should have almost ZERO noise! Is it possible these are fake AD797???
 
Im thinking on ordering from mouser genuine 4 AD797BRZ and replacing those
