Page 11 - Onboard Sound (RMAA 6.06) Analyzation

Gigabyte's packaging indicates that the X48T-DQ6 has an included 'high quality DAC' with its Realtek ALC889A onboard sound codec; boasting 106dB signal to noise ratio -- along with many highlights about its claimed excellent integrated audio. With support for DTS Neo:PC (No DDL though) to go along, Gigabyte seems to have taken integrated audio into some consideration. Let's see how it performances under our RMAA tests with the Gigabyte X48T-DQ6's onboard sound subsystem.
