Bass is very demanding on the amplifier. I haven't used any quality headphones with my surface, so I can't comment, but the ability to provide high current is paramount to experiencing good quality bass. I also don't know the impedance of the surface headphone output, but if it's too high it may not gel with the vmodas.
Spend a hundred bucks and get a small and good dedicated headphone amp. Vmoda also makes them with built in dac, albeit a bit more expensive, but the quality you'll get via USB will be far greater than the surface can output on its own.
