One thing the Lite Transport does have - which I have found intriguing as the only other company I know of that has experimented with this is Audio Note UK - are an implementation of very small output transformers for some kind of digital signal conditioning. You can see them (at least I think that is them - two small black cubes) near the rear of the pcb, adjacent to the outputs. Commentary has been extremely hard to come by, save in Google 'Chinglish' - "RA audio grade buffer transformer for intact wave shape". They may just be part of the balanced circuitry, however. Just don't know.
The other thing, aside from I2S, that I liked in the DAC was the use of high quality output devices - the same ones used by Audio Innovations in their Alto amp (itself a homage to a Quad design, if I'm not mistaken). These produce a wonderfully full range sound of deep tonality.
