I finally coaxed how to rock NOS mode out of Kingwa. The current info on the website appears to be missing a row. The old info appears to be correct (also available at MagnaHifi).
To disable oversampling, you need the jumpers on both IPS0 and IPS1.
The other settings listed (e.g. ATT0/1) are for stopband attenuation.
NOS purists would probably suggest minimizing stopband attenuation and disabling PLL as well. Crazy NOS preppers might also recommend disabling data dithering.
Actually, the comprehensive DSP jumper setting info is still up if you search on Google for it:

Unfortunately, once I start playing with IPS1, I get channel imbalance. Everything pans a bit to the left. One other person mentioned the same thing. Let me know if it works well for you..
