USB Galvanic isolation implementation on EXPERT PRO with CI?

[PeppaPig]

Hi guys, 

Just tried to google information about if USB galvanic isolation is implemented on the EXPERT/PRO/CI products, but can't find much information about it. I heard the CI release has greatly improved the USB performance but not sure the reason behind it.

Does anyone know about this? How is the current USB performance compare to AES/EBU and if it has the galvanic isolation? If not I guess its good to use a USB ISO regen?

Thanks
