Let's face it, a manufacturer can price their equipment at any price they want. It comes down to whether their claims amount to something a buyer can hear.
When I restarted my audio journey 10 years ago, I was trying to get the most performance from the least amount of money. After lots of listening/relistening, I ended up realizing that sometimes you have to pay the money in order to get the sound you are wanting/expecting.
I started with a Bluesound Node, but realized that things could get better sound by going with separates. Lots of DAC's later, I got a lead on the Brinkmann Nyquist II. It just blew away all the other DAC's I had (albeit, they were in the $2K range). I never thought I would spend so much on a DAC, but I did, and I have no regrets.
Whether the DAC listed in the original post outperforms my Brinkmann, I have no idea, but at that price, it has to make the performers come to life, literally.
