Audiophile Pure DSD module without DAC chip

RT audio design, have designed new DSD module for audiophiles. This module doesn’t use standard dac chip converter. The module consists USB digital section with XMOS audio processor, which converts DSD files directly in analog signal, bypassing digital filters and commutations. The second section consists ultra low noises power supply and PCB for output transformers Lundahl and Sowter. The output transformers are perfect LPF and HPF analog filters with low distortions and 0.2 degrees phase shift and low noises. This module can play:

  • DSD Audio over PCM frames
  • DSD64 (2.8224MHz and 3.0720MHz)
    DSD128 (5.6448MHz and 6.1440MHz) by method DoP with 0×05/0xFA markers
  • DSD Native DSD64 (2.8224MHz and 3.0720MHz)
  • DSD128 (5.6448MHz and 6.1440MHz)
    DSD256 (11.2896MHz and 12.2880MHz) on Linux and MAC OS

…. and this is how it looks inside







Coming soon

In 2016 our company will launch in production the new Hybrid dac Orpneus EX
The new dac consists two separate sections:
1.DSD DAC section with WM8742 and output transformers
2.PCM DAC section with AD1852 and output transformers
The DAC case is powered with separate battery power supply.
