Any point in fiber optic isolation without LPS?

[amgradmd]

I recently installed a couple points of fiber optic isolation on my network. One between the switch and my Mac Mini server (TP-Link MC200CM with 15 foot duplex cable) with the other between the switch and PS Audio Directstream DAC (TP-Link MC100CM with 5 ft cable- the MC200CM wouldn't work with my DAC!). As of right now I am powering my PS Audio LANRover and the receiving module for the DAC with my UpTone Ultracaps LPS-1 with splitter. So I'm wondering if there's any point in getting another LPS-1 for the sending units as well. I can theoretically see the benefit of doing do, but does it really make a difference? And is the receiving unit to the DAC the one to power with the LPS if you can only choose one fiber module? Any input is greatly appreciated!

You could test it on your own setup with a cheap LPS or even a cheap battery supply (cellphone backup power). It very well may not make a difference.
