I am afraid that you cannot replay DSD files with that combination.
The LIndemann does not support DSD at all as far as I can see from either MKI or Mk.II specifications . It is an entirely PCM device.
However, irrespective of the above, dCS Elgar+ processes DSD via an IEEE 1394 interface (Firewire) but also requires a 44.1kHz wordclock source as the IEEE1394 interface does not support a clock signal. You do not have either of these .
Sorry but there it is.
