Jitter and clock phase noise are different ways of quantifying the same phenomenon. Jitter is measurement in time, phase noise is in frequency.
Mathematically the relationship is quantified so engineers designing digital components, DACs, ADCs can filter the jitter/phase noise. Modern DACs even cheap ones do a good job of this.

Congratulations you added something to the thread that I can agree with. The jitter reduction ultimately occurs at the DAC although it's done so by controlling "pollution" of the DAC from the switch.
This switch bang for the buck is only beaten by the late Tim Mrocks total contact in my experience. Well recorded live music events on you tube , mind blowing sound quality in my system with this switch. Tonight I'm listening to Hauser playing with many guests in an amphitheatre in Pula. Wow! amazing acoustics! Amazing music.
