NUC ROCK, Schiit Gen 5 USB, LPS

Hello. Has anyone tested the usefulness of a LPS with a NUC ROCK directly connected to a Schiit DAC with Gen 5 USB? Schiit Gen 5 USB is touted as being able to clean up a lot of USB noise issues (and the forthcoming Gen 6 should be even better I hear). I’m thinking that the better the USB input is on a DAC the less beneficial the LPS on the ROCK would be. Any thoughts?
