lalitk: By streaming, I was referring to a service like Qobuz or Tidal. There don't seem to be any services that stream DSD. As to downloads, SACDs are often less expensive than downloads and don't take up any hard drive space. I should note that downloads still require hardware.
I invented the D.BOB because the DACs in players are not as good as good as external DACs with independent power supplies. One only needs a reliable player, the D.BOB and an external DAC. When I went from the DAC inside an Oppo 105 to using it just as a transport, connected to the D.BOB and then to that first Mytek DAC (Stereo 192DSD), my world changed.
