The digital inputs are much better then using the ethernet with the K50, as it reclocks the digital outputs but does not reclock ethernet output or USB output. The K50 is optimized to use the 75 and 110 ohm digital outputs. Before my K50 when I used my Roon Nucleus or even a computer I preferred the ethernet port by a small margin. My ethernet was/is optimized as well with audiophile switches, clocks, filters and cables. The Ultra DAC has an excellent clock and renderer for network connection. You are using the K50 like a K40, I recommend you try the digital inputs with a good cable. Even with an average digital cable it sounded much better then the network. I do not have DSP speakers, I use the XLR analog outputs on my the Ultra DAC to my preamp.
