I haven't done anything yet but try to research online to no avail.
Haven't tried the usb connection on the preamp yet but have the CXN hooked up with the digital coax and also the balanced audio out to see if I could tell a difference switching between the two.
On the coax the preamp always reads the 44.1K and the balanced doesn't show anything and I can tell a difference between the two but not sure which one I prefer.
