I have a Roon Nucleus v1 that directly feeds my Schiit Yggy DAC via a USB Disruptor. I recently install an HDPLEX 300W Linear Power Supply for the Nucleus and notice a distinct lowering of the noise floor. The magnitude of this lowering was less than the lowering when I went from a MacBook Pro as my Roon core and server to the Nucleus, but it was there. I then also used the LPS to feed the 5v needed for USB to the USB Disruptor and noticed a further lowering of the noise floor, with less magnitude than the installation on the Nucleus (but it was "free").
