Using an older upsampling dac with a new Bluesound Node


I have a Musical Fidelity A3 dac that upsamples to 96/192khz. My question is does it recognize the high res signal from the streamer and process it nativity or does it only recognize the standard sample rate of 44.1khz and upsample that? Would I be better off using the analog output from the Node?
