I purchased the D2 recently to replace the Wadia M330. The LUMIN app’s user interface is excellent and the balanced output further enhanced the sound. TIDAL runs flawlessly.
However, after trying out a friend’s ROON software, the itch is on.
Question is… would I absolutely need a Roon Nucleus or are their other alternatives?
Current system is IPAD PRO -> LUMIN D2 -> KRELL INTEGRATED -> SPEAKERS
No programming needed. For simplicity you can just buy Nucleus if you want a dedicated setup instead of using your existing computer. Since you asked for alternatives to Nucleus, a good alternative is to run ROCK (a special Roon software distribution) on NUC.

You’ll also find many ROCK discussions in this forum.
If you’re planning to buy one, check out the rumors about MacBook Air 2018 with Kaby Lake CPU. When you do buy one, choose the option with the fastest CPU.
I also have a Lumin D2 and I’m using a Macintosh Air as my Core device. They’re a perfect match as far as I’m concerned and I have no need for the Nucleus. As you probably know, the Air has a SSD drive built in.
