If there is no data going over the SATA cables (as in my case) and the signal drivers for these cables are not enabled (as per the SATA specification) then changing the SATA cables is akin to changing any other wire in the box that is not directly carrying a digital signal. It will probably make less difference than changing a power wire, including a SATA power wire to a device that has active digital processing (e.g. a SSD or spinner, both of which have a microprocessor inside).
The problem is that this is all speculation. Unless some method can be devised to give rapid, repeated and reliable measurements that can be correlated to long term listening results, making progress by trial and error listening tests is going to be slow, akin to searching for one's car keys in a dark room without a flashlight.
IMO effort would be better spent on simple devices to provide analog digital separation using a narrow interface between the DAC and the computer. The narrowest possible interface today is the IIS interface with clock at the slave end or the DSD equivalent. Here one is concerned with the operation of a few hundred transistors and the necessary ground and power wiring, not billions of transistors doing unknown functions according to impenetrable software. If a USB DAC is used it must have this isolation built in, since the USB attachment in the DAC is itself a computer due to the complexity of the USB protocol.
