If you're conecting a SPDIF you have to check the strength of the signal, some DAC's output from 0.5V,  1V ,  2V,    2,5V , 5V.  Check the maximum rated input for the essence one. Usually the DAC/AMP are made to work with a specific level of input and apply Gain accordingly. so if you're way under the maximum rated input you'll get low volume.

 

A friend had this problem with NFB-6 because he was using a DAC that has 1V output, so he had to mod the NFB-6 so it would apply a higher gain.
