Network Acoustics Eno Streaming System vs SGC Optical Isolation System

I replaced my EtherRegen (fiber into the A side) and LPS1.2 power supply with the following converter and an iFi power supply.   I couldn't hear a difference after the switch.   I purposely picked the StarTech just because it wasn't the cheapest (actually is pretty pricey compared to $20ish ones on Amazon).   I have no idea if it makes a difference over the $20 ones but bang for buck compared to the EtherRegen was a big bonus for me at least.   Just adding 10 feet of fiber between my router and EtherRegen or StarTech was the biggest improvement for me, outside of buying a pretty decent streamer.

Appreciate the discussion. For a while I've felt like the amount of tweaks that could be done to enhance streaming and reduce noise can be overwhelming to grasp - FMCs, ethernet cables, LPS, servers, modems, switches, passive devices (Eno), routers, hard wired from a mesh system vs WiFi, etc.

For the past two months I've tried to educate myself and played around with some cheap switches, RF/EMI shielding tape around cheap switches, new modem, placement of hard wired mesh system/point, and cheapish ethernet cables to see if I could hear a difference before taking a deeper dive. 

For my wallet I was hoping NOT to hear a difference, but I do. This practice unfortunately reaffirmed my belief that everything matters in this hobby. 

@jjss49 appreciate your experience. @oddiofyl and @jerryg123 and @ddafoe appreciate the links - I have them in my wish list.

I like the passive nature of the Eno which also equates to less cables - I would imagine the passive nature bypasses any noise that it may otherwise induce if it were being powered, which is what we're trying to reduce with an LPS for the last FMC, right?

Exactly. After trying fibre optic FMCs and iFi power supply on the switch, I opted for the Network Acoustics Eno streaming System directly from the EERO mesh access point. No switch. I liked what I heard. To me it sounds fuller and more natural than what I’ve heard with the FMCs.
The Eno also does not introduce any additional noise due to its passive design and cleans up enough of the incoming garbage. I also ended up eliminating all of the clutter associated with the FMCs and switch. It’s a more of a neat installation that brings in enough of an improvement to not need all the extra modules, power supplies and cables.
Few important things to take into consideration…components first and foremost. Clean power. Then filters and cables.

+1 @audphile1 on the passive filter.  I have a Muon in each of my systems and a nice improvement!  In one of them I also still have the Ether Regen in front of the Muon.  It adds, but not as much as the Muon.  

Optimizing FMC isn't as simple as one may believe. There is generic route via switching power supplies, generic with one or two lps. Then there is the Sonore route via upgrading FMC (two OpticalModule) only or FMC and optical streamer, these can be powered via various quality LPS. And then we can upgrade Sonore products with this, https://audiophilestyle.com/forums/topic/62352-finisar-sfp-modules-for-audio-grade-network-switch-group-buy-for-audiophilestylecom/ My next experiments will include Finisar SFP industrial grade and optical cables.
