Cheapest way to enhance SQ with digital streaming

I could not stop but post my observations on remarkable SQ improvement with just a small change. I have been using digital streaming predominantly and have tried many things (cables, conditioner, room treatment). Everything does matter and they all did improve the quality without doubt and are definite investment. But after going through some reviews of fiber optic for Ethernet and their noise reducing properties compared to copper cables, I thought of giving a try. I connected Ethernet cable from router/Ethernet switch to media converter and fiber optic from this media converter (need SFP module) to second media converter (with another SFP module). Then regular Ethernet cable went from this second media converter to server/streamer. Basically the idea is to add fiber optic cable between the router and streamer, which will reduce the noise. But, wow, the difference was huge and amazing. Not sure how to explain the improvement, but the SQ was more fluid, melodious, fast, clean and separation of instruments were clear. The total cost for this was less than 150 (on Amazon). Apparently, as the fiber optic cable conductors are made of glass, they carry less noise compared to copper and also cost very cheap. Compared to money spent on other component in my system (have spent quite a lot), this is the most cost efficient and gave more improvement in the SQ. I am still amazed by this and very happy with what I heard. I feel negligent not to share with my fellow audiophiles, who are trying to get the best out and improve their system, sometime spending quite a bit for small difference. I guess, since the cost of trying this is so cheap (please don’t make me feel guilty for telling 150$ is cheap), try yourself and see the difference. On a different note, have been reading that use of Ethernet switch also does some “saucery” (I am no technical guy, but do read quite a bit of articles on audio) to reduce this noise to improve SQ and combination of fiber optic and the Ethernet switch takes SQ to different level. Will try some audiophile Ethernet switch sometime (may be uptone ethergen or Sotm snh-10g) to try out as I am very intrigued. 
That’s my findings as well Romney, to go a step further put ur router, switch, FMC on both sending and receiving on linear power supplies with good power cords and if you want to go even further put a bybee IQSE inside the LPS,s and a MUST’ put all the above on good shelf and footers. The footers well make a huge impact as well.

Check out  my systems page for the lengths I have gone with the above .
I saw your system and looks well planned and organized. I will definitely buy LPS for routers once I get new ethernet switch: yet to decide between Sotm/ethergen/melco S-100. 
How do you put or install Bybee IQSE. Do you open the unit and put it inside or just place it next to it. 
Yes I just unscrewed the top on the W4S PS 1 and attached the IQSE On the top . 
It’s all about execution , attention to detail and imagination.
Over on whatsbesrforum in the computer based music server forum there is a lot of high praise for the melco S100.
Hi @romney80,

Would you mind sharing the specific Ethernet > Fiber > Ethernet items from Amazon you used resulting in your SQ improvement?  If your are more comfortable with private messaging this, please do. 
Here are the items: 
2 of “Gigabit Ethernet Multi-Mode LC Fiber Media Converter (SFP SX Transceiver Included), up to 550M, 10/100/1000Base-Tx to 1000Base-SX”
Fortunately this comes with SFP module so you don’t have to buy that separate. 

One of “FiberCablesDirect - 15M OM4 LC LC Fiber Patch Cable | 100Gb Duplex 50/125 LC to LC Multimode Jumper 15 Meter (49.21ft) | Length Options: 0.5M-300M | 10/40/100gb mmf sfp+ 100gbase dplx ofnr om4-lc-lc”.

Then you can use Ethernet cable of your choice. 
Yes, I have been following those threads on ABF and they went through great deal on the above ethernet switches. As per those discussions, Melco S-100 > Sotm > ethergen. Will get that sometime and try it out.
