I own the Yggdrasil and give it two thumbs wayyyy up.
what hasn’t been discussed to you so far is the ease of streaming with associated software. I own a Bluesound Node in a bedroom system, and the Beaty of it is bulletproof software that doesn’t crash and hardware that robustly comes back from being accidentally turned off (like with loss of power). The software interface matters a lot.
I use an Aurender N100H with my Yggdrasil, and one reason I got it is that the controlling software was intuitive and easy to use, a bit more sophisticated than the Bluesound but with a steeper learning curve. This combo sounds much, much better than the Bluesound. However, when this unit loses power, the return to functionality is not graceful. Often several reboots are required, and I mean hard reboots. It is not possible to follow the software commands from a controlling iPad, as the unit doesn’t communicate after losing power. The Bluesound is a much more robust consumer product.
so my recommendation is to play around with controlling the server before you buy.
