    Thanks for the quick response, you rock! It was exactly like I suspected then, Gene having an opamp and Hero doesn't. But it doesn't totally make it easier for me to decide though, I will be using my own "amp" (it's a bit special amp design why it shouldn't be treated as a traditional one, being fully analog design for example) and it also makes the EMI noise a bit louder (unacceptably loud on this new Z87 ASRock board I got). My biggest priority would be getting as low EMI noise interfearence as possible, this is by far the number one priority in my case. That's where I don't know whether having an onboard opamp is more beneficial or destructive as from my experience with at least external amps, they tend to increase the volume of the noise unless you have some more expensier ones which filters out the noise. I'm not either any guru on these things so can't really theoretically say how it should work.

    But I'm thinking logically; ALC889A which I had with my previous socket setup didn't have any onboard opamp and noise was MUUUUCH LOWER than on the ASRock Extreme6 (featuring ALC1150 + TI NE5532 opamp) however in the ASRock case I doubt the difference lie in the opamp alone but yea it gives food for thought...

    Have you like any ideas about these things or is able to get further info about it whether Gene or Hero should be having lower EMI noise interfearence (buzzing, popping, chirping sound due to HDD, mouse activity, high system load etc), at least on the paper. This would be so much appriciated, ordering one of these boards will take some while here when I'm from Finland, neither am I too keen on testing both Gene and Hero to find out... I'd just wanna get a board with acceptably low onboard chip EMI noise interfearence so I can totally forget that and focus on overclocking and actually enjoying my new setup without having to pull my hair out.
