I'll wait for a review before deciding on this "poison" haha... I wonder how it compares to X-Fi's CS4382

this is mine... not a casing though... kinda like those caps around.. so just build a layer of protection for it..

WARNING: Other sound effect other than the foobar will be very loud if you do as following:

For people using foobar, I have a solution for this to get back the lost resolution

Go to preference-> Playback -> ReplayGain->Preamp
Set the both with rg info and without rg info to -20.0db (Left most position)

Then go to your windows volume and set it to max. Now you will control the volume through the foobar and not from windows.
Another info is ASIO driver support this DAC very nicely, you get even cleaner sound from ASIO. For ASIO installation please ask uncle google.
Thanks chchyong89 to point this out,  now it's there is really fine sound flowing into my ears.

it does not matter. You should not control your volume using software attenuation because you'll lose bit resolution no matter what.
The best way is still to use an amplifier and control the volume using that device. As for clipping prevention, all you have to do is to replaygain all your songs (prevent clipping mode) and they'll be fine.

Just try it yourself if you can hear difference,  if got improvement then you shall live with it for a while. If you hear no difference then can always use back the master volume.
