anyone try to install other driver besides kx driver?

lonekey

once, i installed the openalweax for foobar2000 while using opeanal output, of course, it is no longer needed after the lastest openal output plugin. yesterday, i tried a A3D driver 3.12 in my sblive besides kx driver (3533b), then i tried the a3d demo(28.1m), it works well(A3D,DS3D,stereo), amazing ! so doesn't some other a3d demos. except the reflection part in one demo. this encouraging me to try further, even though i won't use them at all, i think it is really funny. i tried to install eax2unified driver , but i don't know how to find out if it working or not. Is there a benefit using these drivers besides kx driver?
