Yes' there is an improvement using LPS for the router and FMC , Im using the W4S LPS1 and do not know if its fast acting or not but there is clearly an audible difference with the LPS then without. I even have the LPS,s plugged into a power conditioner.
For the FMC nearest the Dac I use a battery. I actually have 2 batteries for this so when one runs down I simply hook up the 2nd battery.
