I use glass Toslink optical from Amazon for connecting my TV audio to my HiFi system, and it sounds excellent. I'm actually amazed how good it sounds through my DAC/audio system, given the bitrate/sample rate.
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.

Just an update from February with this inexpensive approach. I had been looking around and examining 5v linear power supplies. Finally pulled the trigger on a unit by Solupeak. So of the two media converters with the fiber connectors, I have one on the "dirty side" as they call it. Result? Astounding, simply astounding. I was hoping to see a little improvement but once again, it just made me regret not doing it sooner. Again, my system is unique but consists of 65w tube monoblocks, RME ADI-2 DAC, McIntosh LS340 speakers, using a 2011 Mac Mini running Audirvana's Studio software. The depth of the sound, the separation and black space all take another major leap. I'll add that my setup is especially sensitive to changes, even a small tube can offer some nice change/improvement. Also running a LPS on the RME DAC. That was very nice but this is more than I could have imagined. It's going to be a spell digesting this one. Thanks again to @sns and @romney80 as this is a superlative low investment for big bang results. Thanks to everyone else who also shared their experience. |
Good to hear another success story. The 2 generic FMC’s with fiber optic cable made a significant improvement on my system as well. I tried adding an iFi ipower LPS plug to my FMC’s and it made no sonic improvement over the stock wall plug. Ended up being a return. Scratching my head as to why? Anyone else have no improvement using a LPS on FMC’s?

@tksteingraber The only reason lps on at least second FMC would be lack of resolving ability of entire audio system, or lps not of sufficient quality. I can hear differences with lps on only one or two FMC, with different lps, with different power cords used with the lps, and with lps connected to battery storage device or ac power conditioner. Try a Teradak lps with decent power cord and report back. |
@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. |
