Ethernet - Analog/Digital Signal Clean Up

I use an EtherRegen on the streamer side of a wall wart repeater. 

In addition to answers you receive here, you may want to run a search for your topics as you will find additional discussions in threads such as this one and this one.

Back to your questions, I use fiber optic cable as you described but my run is 45 feet from my router to my main system. I use LPS at both ends in place of the small wall warts that come with the converters.  After conversion, a short CAT 8 Ethernet cable run from the fiber converter to:

• Bonn Silent Angel N8 switch (made by the same people who make the English Electric Network Switch 8), then short Ethernet cable to 
•  GigaFOILv4-INLINE Ethernet Filter (with LPS), then Network Acoustics Streaming Cable to 
• Network Acoustics ENO filter, then the captive streaming cable to
• music server

The set-up works fine and sounds great but I would caution that to me, no one of these things made what I would consider a significant difference in sound quality, especially to the transitional levels sometimes posted about in these forums.  Whether that is my components, my overall system and room, or my hearing, I hear nothing more than subtle differences with these tweaks/digital cables.  

Aud,

I am about one week into the set up you are using. Soon  I will plug the ethernet cable from router to streamer for a sonic comparison. I did not hear a night and day difference with the ethernet converter boxes and fiber optic cable. However, it’s a very inexpensive experiment

I have the following setup:

cat8->DXE filter->Lhyaudio ocxo switch->etherregen on Antelope audio 10m clock->DXE filter->Emo EN70HD->InnuOs Zenith Mk3->USb->Holo Audio Titanis->Intona Isolator 2.0 Industrial->Antelope Audio Zodiac Platinum on 10m clock. The clock, USB connection and Dac are all powered by Sean Jacobs DC3/4 Lps, the Etherregen by Zerozone 2020 LPS.

Admittedly this is a ridiculous amount of boxes, yet: it took me 3 years to not only figure out the right components but also the sequence.

My principal lessons are as follows: avoid any noise from EMI/RFI/Ground level through galvanic isolation, use shielded cables on digital connections and get the best clock you can afford to control the DAC, ethernet and USB connections. Use digital filters on any clock or ethernet connections. I have not played with optical but worked hard in finding good ethernet and USB cables (0nto cat8 and Intona Reference USB)

All…

Tons of good info guys thanks!

@tuberist make sure you use your best Ethernet cable into the streamer. I have already done the comparison you’re about to do.
If possible plug the converters into power conditioner. Difference is not night and day but significant enough at least in my system to keep this set up. I tested this with several songs and consistently heard more natural tone, better imaging and soundstage than what I get with eero direct into Lumin. Depends on your streamer, system, room, etc. YMMV.
