I rebuilt my office system since I recently lost a bigger room to a much smaller space. I had Magnepan LRS+ in the bigger space. I sold them and bought some used Magnepan Mini. I am in near field listening with this setup, almost like headphones.
The best sound I got from this setup was with a CODA #16 amp and the Schitt Yggi+ OG DAC. Now this is a crazy price difference between the electronics and the speakers so that was not going to last. I also needed the amp and DAC for my big system.
After a lot of permutations with gear, speaker cables, sub, and placement. I came to a realization. The Schitt stack that I am using now has some great synergy and is almost as good as the CODA #16 and the Yggi+ system. The speakers are not that great to really get much of a delta in improvement with the more expensive gear. Really good speakers, but not great, the soundstage is great.
Schitt has a stack, Giga Stack, they are calling their answer to an integrated amp with DAC. I am now using the same thing; except I am using the Schitt Yggi+ LIM DAC. The LIM DAC is likely not as good overall as the DAC in the Giga Stack package they are selling. There is some great synergy with this setup. The Wotan F amp is as good as 2 $8k amps I have owned. The Kara F preamp is rather good and has 3 outputs for speaker, sub, and my headphone amp. For an office this is an amazing set of gear.

Is it better than the Luxman, I would say yes. I like Luxman but the Wotan is a powerful beast and clean sounding. The Yggi+ DACs, even the worst one, the LIM, is coming from a DAC designer with a very impressive pedigree. I plan on upgrading the LIM DAC in the summer when the next iteration of the Yggi+ come out. The Gungnir 2 DAC in the Giga Stack is a step towards the next iteration of the Yggi+.
BTW - I got the Forkbeard option on the Kara F and Wotam F. I find it very useful to be able to control each unit with my iPhone, especially the amp.
