Which profile just passes the bits, no DSP, no upsampling?

I am using Serviio as a media server to a PS Audio Direct Stream DAC, and need some help on choosing a profile that best works with this DAC. PS Audio suggested I find a Serviio profile that just passes the bits, no DSP, no upsampling. Anyone know which one that would be?

The Generic profile performs no transcoding, so it should just be passing the stream bit for bit.
