No clue... just quoting their marketing material.
They would say noise probably but in my opinion, building a big arsed server with all those cores and all that memory and all that extra power needed cant lead to lower noise.
As I stated previously, the best (and obvious) topology is some server (as big as needed to sustain your upsampling requirements) in another room and a low powered end point (no disk, ram boot etc) into your DAC.
It makes no sense (to me) to hook something like this (sitting in your rack) into your DAC.

PS. And related to my hypothesis (based on looking at systems on the internet for decades) that most (> 70%) people who buy mega buck stuff are generally not interested in sound but rather the "look how much I spent", we have another system on Mono and Stereo, which again lives in a marble temple (to bad sound).
The speakers are around $US 65K and no clue about the electronics in this install..but no effort has been made to get any sound quality from these speakers.
