[...] Like i said, you don't have the equipement to back it up but you engaged your soul by saying it is the true. But sadly i heard the complete opposite from people looking "internetably" (lol) honest too".
So, the best way is just to basicaly try it out and see by yourself. Better? not better? placebo or not? matter of tast or measurement to back it up? it's a mic mac

Have a good day wherever you leave
Hi pocahontas,
I only trust 2 things in audio world:
- 1'st would be measurements done carefully with dedicated equipment that should proves that DAC+AMP are not oscillating and are within acceptable "audiophile" parameters;
- 2'nd would be A/B and blind A/B tests done by at least 2 persons with decent hearing (A/B tests done either between 2 identical DACs/AMPs, either by using a "reference" system to compare with and write down all noticed differences).
What you need right now is to find someone having both ODAC+O2 and ALC1155 motherboard to do this A/B test I was speaking above (though I believe in one of my links provided in an earlier post there was someone on another forum that already compared that).
Also, just by looking at ALC1155 specs from the datasheet and comparing with ODAC doesn't really proves anything because ODAC and O2 measurements were done at RCA/outputs plugs with scopes and AP Precision equipment, but "some motherboard manufacturer" will only tell you the spces provided by the ALC1155 itself in the datasheet and not the actual measurements done at RCA/outputs or headphone plugs. It's hard for me to believe that a manufacturer will perfectly implement a great audiophile DAC & headamp inside a "usually very noisy" computer case and powered from a "usually very noisy" switching power supply (try searching over Internet about computer PSU noisy and ripple). So, yes your computer PSU is going to influence a lot your motherboard DAC's sound, unless you're spending a lot of money on a high-end PSU with decent ripple & noise figures...and usually most people is swapping computers at every 3-5 years to get most of price/performance ratio, so perhaps would be wiser to invest in external DAC/amps.
Have a great day yourself,
Raul.
