ISO-PLUS Ethernet RF Filters vs Fiber Optic Cable

Well, I am using an etherRegen switch sending the optical cable (fiber optics) to my Lumin dac. I couldn't believe the improvement in sound quality with using the optical cable over ethernet cable.

Optical is the only hundred percent isolation solution. Now its been reported on another thread Innuos claims optical conversion generates noise that makes it inferior to ethernet. I find that highly doubtful, based on both my experience and many others. On the presumption it may be true in any particular setup, there are a number of variables that may make this possible.

FMC's (fiber media converters) are not of a single quality. You can have generic FMC powered by SMPS, generic powered by LPS, and finally, much higher quality FMC such as the Sonore Opticalrendu line. I have experienced all three levels of optical conversion, Sonore plays on entirely different level.

I've not tried the positively reviewed, and I assume very good performing Acoustic Network Eno, but it, or any filter cannot one hundred percent completely isolate network noise as optical can.

For the skeptics, I only ask they try optical vs. their best ethernet solutions and report.

I'd also add, one should read John Swenson's papers on network optimization, John is perhaps preeminent audio network engineer.

I use both fmc optical and the accustic revive filters, 3 of them actually fmc to switch , switch to server , server to dac.
