We recommend you consider the miniDSP SHD (or Flex) as a pre-amp DAC with Dirac Live. With Tidal as the digital source going into the miniDSP SHD via LAN. The digital signal remains bit-perfect through all the DSP / Dirac Live processing. This signal is then delivered over the I²S Bus to the SHD’s internal DAC and premium analog output stage, ready to drive and use your Yamaha A-S1200 as a power amplifier.
