On my motherboard MSI P67A-C43 (B3) the green line out jack on the back of the motherboard sounds un-amped compared with the front panel audio jack. There is significantly more bass coming from my headphones when connected to the front panel audio jack. All settings are the same across jacks, no EQ. This has happened on a previous motherboard also, it makes sense for the front panel audio jack to be amped compared to the line out as you would usually plug headphones into the front and speakers into the rear jack.
ALC892 is the onboard audio which i assume has a built in AMP that is only connected to the front audio panel...because speakers have thier own amps?

Is this assumption right? if so I am hoping the amp that is obviously powering the front audio jack will be good enough for the Pro 900's I have just purchased.
