I was briefly looking into different "NO-DAC" projects ongoing on the net.
Basically these use Amanero or JLSOUNDS USB-I2S/DSD interfaces with direct DSD processing capabilities, feeding the DSD stream into a basic LowPassFilter. There are different projects with different complexity (FlipFlops/Transformer/Tubes/...). Since the PCM-DSD conversion requires serious horsepowers, using squeezelite+sox-DSD on a PI2 might not be the way to go. In this case a powerful server needs to do the conversion. Most of the discussions I looked into were referring to HQPlayer as the DSD engine of choice. HQPlayer seems to have quite well done filters in place. There are two big questionmarks. 1. I have no clue how the sox DSD-fork compares to HQP. I don't know if it would make sense to try the sox approach at all, since the conversion is a crucial part of the story.. 2. I'm also not sure if a project LMS&sox(dsd-fork)->squeezelite->JLSOUNDS-USB->LPF @ up2 DSD256 would work. Let me know if anybody went that path.
