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.

@sns Thanks for input.  Ordered the higher quality LPS to give it a try.  

On a separate topic I thought I would give battery power a try for kicks.  I already had a Solar back up power outlet (a 24 volt set up) with a pure sine-wave  inverter.  I ran a 14ga 25 ft extension cord from the outlet to my system and connected all components.  Wow....background got quieter, volume appeared louder, could hear all the separate instruments, vocals, noises much clearer and stage expanded.  What a change for no added expense.  Prior to this my system did not have noise issues and running on regular ac power does sound warmer/softer in a good way.  Just different. I think I am glad I gave it a go.  Ughhh...Now I have to figure out how to hard wire the battery power in with romex and a electrical box.

@tksteingraber Well that's good, proves your system resolving enough. Don't know if I mentioned in this thread, but I have tried battery power with dacs and lps for various streaming devices, always went back to ac with my BPT 3.5 Sig. power conditioner as superior. I too hear warmer/softer with battery, but this less satisfactory with time, noticeable decrease in transients, micro dynamics, music lacked excitement, involvement with battery power.

 

My take is battery power could likely be preferable to non optimized ac, but with dedicated lines, top notch grounding and power conditioning, ac better.

@sns ok my LPS (paid under $100) arrived today and I must say the higher quality LPS  moved the needle right out of the box.  The bass is a bit heavy but I will give it some time to break in.  Anyway it’s a keeper. Similar improvements, to a lesser degree, than what the battery power gave me that I mentioned above. Contrary I would not recommend the Ifi ipower LPS wall plug...it did nothing for my system. Amazing how an LPS can make quite a noticeable improvement on a FMC. Thanks for the suggestion to give it another go.

@tksteingraber Sounds good, your results what I'd expect. Just a reminder, power cables on lps and ac feed, power conditioner will also help. Lps and same upgrades on other FMC will also help, although to lesser degree.

 

Even the dc cables (from lps to FMC) can have an effect, at this very moment another thread here in regard to this upgrade.

"wow, the difference was huge and amazing"

I have been around the block and back on this stuff but I just don't come to the same conclusion as above.  I have 45 feet of fiber, converters, LPSs, Network Acoustics ENO and Ethernet cable, GigaFOIL v4, and the Silent Angel Bonn N8 switch.  My internet is high speed with an Orbi mesh router system and a standard switch at the main router which separates the audio stuff (the Silent Angel Bonn N8 switch is near my components). I am using Mojo Audio's DejaVu server and EVO DAC and with those components, it is my experience that any sonic difference/improvement resulting from all the digital "add-on stuff" is subtle, if any.

I decided to simplify all this "stuff" by moving the Silent Angel Bonn N8 switch near my main router, running 45 feet of Ethernet cable from that switch directly into the GigaFOIL v4 (which is near my components), and then running the Network Acoustics Ethernet cable from the GigaFOIL v4 directly into my server.  The switch, router, and GigaFOIL v4 are all on LPS. 

I am having a hard time discerning any sonic difference resulting from the simplifications.  My system sounded good before the changes and it sounds good after.  I may reintroduce the ENO and/or try moving things around a bit just for kicks but I am skeptical this stuff does much of anything, and certainly not to the levels discussed by some on these forums.  Maybe I need to listen more, or maybe the add-on stuff is more helpful for systems located in noisy environments.
