Bluesound Node Clock Upgrade Neutron Star 3

Has anyone upgraded the 24Mhz oscillator or installed a reference clock, xcxo,or tcxo, on the Bluesound Node? Has anybody used the NewClassD Neutron Star 3 reference clock or the Neutrino 2 clock in any project? What was the process? Were there big sound improvements? Any recommendations for a clock upgrade for the Bluesound Node?
