Virus TI Snow, Very low volume on headphone jack. Please help.

[Androgen Lovers]

Our Virus TI Snow, has very low volume on the headphone jack. (Same volume on the other mono jack)
Is this normal for the Snow? Using any set of headphones sound very soft, even our Pro Grade AKG's.
At half volume depending on the patch you hear very little. At full volume it's not much better, certain patches are easier to hear due to their programming, but mostly not loud enough.
Our iPod Nano goes much louder w/ no headphone amp. Also our Triton Extreme, JV-2080, and Fire Face 800 all go much louder than the Snow.

I contacted Access email support, and that proved useless, this guy was either not listening to me, or was too stubborn to admit that the Snow's are indeed not very loud with out an amp. It "may' even be because it does not have a dedicated headphone jack. Snow users PLEASE help.

A Great Many Thanks In Advance
