Good to know, but not relevant in our case, we are exploring the D1.

It's definitely reasonable when compared to the D2, but it's still 
relatively expensive.

Low price, good power output on *all* channels, good fidelity. robust 
linux multichannel support.

not a big list, eh?. :-)

onboard stuff tends to only provide amplification on the front channels 
and expects that the user will provide a separate amplifier for rear and 
surround.

Sound *cards* tend to have onboard amps for all the channels because 
they have the pcb real-estate to spare for that sort of thing.
