The DSD signal can be directly used to reconstruct the original analog signal with a simple RC filter.
This method allow to create a very simple DAC without a DAC chip with sonic performance higher than normal DACs.
At this time there is only a commercial product using this method to convert digital signal to analog output by LampizatOr (see review).
The output wave have a DC component of 1.65V present only during DSD playing so with a normal firmware if you change track or click pause a high bump will be reproduced on loudpseakers.
I have an active collaboration with Amanero srl so I have request this new firmware that keep an empty output signal any time there is not DSD signal to reproduce.
Using this software there is a bump only at the switch-on and switch-off but you can add a relay to eliminate this problem.
This DAC work only with DSD but you can play any PCM tracks converting these in DSD with some setting on your JRiver or Foobar2000 player while this playing.
There is a big benefit to convert tracks in DSD also using a normal DAC DSD converters.
