@sns were you able to set the Laiv to "source" clock with Gaia i2s? If so, is it the 12th gen Gaia? I have an early Gaia and no such luck for me.
@dbb before giving up on the P30, there are some upstream tweaks that take you deeper into analog territory. I thought I was done with USB regeneration until someone brought over an SOtM tX-USBultra regenerator w/ Ferrum Hypsos power supply. Shocked me and the cost is fair. Another one is Network Acoustics Muon Pro. I can't defend their pricing but the results I can. Using the Muon with NA's Ethernet cable was too heavy handed in my setup. I preferred NA's Muon w/ JCAT gold, or NA's ethernet cable alone.
