Network optimization for serious streamers

In my ongoing experiments, now going on seven years, with network optimization for streaming I've discovered a number of optimizations that should work with any ethernet ISP.


I've tried a variety of ethernet cables, modems, routers, switches, FMC, ethernet filters, the following is what I've found to be most effective optimizations.


I'll start with ISP quality and speed. Recently I discovered 500mbps to be preferable to 300mbps. Along with upgrade in speed, modem capable of 1gb service replaced 600mbps, both have Broadcom chips and powered by same lps. Can't say which more responsible for improvement, speed or modem, presume speed has at least some role in ping time. As for ISP, there is importance in ISP server geographic location to you, shorter distances  means lower ping time. For information as to how ping time affects jitter-


Now for modems,  modem close to audio system is most favorable, extending coax cable preferable to long ethernet cable. Coax more resistant to rfi and closer positioning to system means one can more easily afford top quality ethernet cable for modem to router connection. The modem should use Broadcom chipset vs. inferior Intel Puma, Broadcom chipset has lower jitter vs the Intel. Modem should be powered via external lps using quality DC and AC cables, lps to power conditioner for ultimate performance.


Following close positioning of modem to audio system, router should also be placed near modem in service of same advantage of making highest quality ethernet cable more affordable, in this case, modem to router and router to switches, streamers and NAS. Router should be powered with lps, this lps should be able to provide more amps than router requires in service of providing greater reliability, having lps with reserves of amperage means lps runs cooler, heat is enemy of reliability, longevity. As with modem, quality dc, ac cables and connection to power conditioner.


The next finding is new to me, provides very meaningful upgrade to streaming sound quality. Noise from wifi, injected both internally to router and externally with routers sitting close to audio systems has long been a concern to me. I have quality Trifield meter which measures rfi, router with operational wifi manufacture obscenely high levels of rfi, rfi is noise, noise is enemy of streaming at level we're talking about here. And its very likely the more wifi devices one has in home the higher the levels of rfi produced. This noise is then injected into following cables and streaming equipment. One may convince themselves FMC totally isolates this noise, and while correct, it doesn't mitigate the noise and masking going on within router. The only way to eliminate this noise is turning off wifi. And then, how to provide wifi for the many  wifi devices we have at home? The answer is to connect a second router to the primary router. The primary router will only provide ethernet for streamers, switches and/or NAS in audio system, also for the second router.  Second router provides wifi for the home, this scheme keeps vast majority of rfi out of audio system streaming chain. My own measurements find rfi significantly diminished in primary router, more than mulitiples of ten times lower vs wifi enabled. This was seamless install with the Netgear routers I'm using. There may also be value in provisioning higher quality routers. My new primary router, Netgear XR1000 is marketed as a gamer router, claims of lower ping time, latency, jitter vs other routers. Since my old router, Netgear RS7000 didn't have means to monitor ping time I can't provide evidence of this claim. Whatever the case, my XR1000 ping time test measurements are as follows, 25.35ms highest, 16.50ms lowest, this is A+ measurements against objective criteria. Ping time under load is download 25.93ms, upload 37.34ms, idle 17.31ms, this rates as A. My speed of 565gbps rates B grade, likely need 1gb service to get A here. At to how this all pertains to sound quality, adding up the upgrade in ISP speed and the off loading of wifi is without a doubt one of the most substantial, if not most substantial network upgrades I've experienced. While I  long considered my setup as having a vanishing low noise floor, with this setup I heard a new level of vanishing if such a thing is possible. Even more astounding was a more analog like presentation, while I wasn't aware of even the slightest digital presentation prior, this upgrade certainly exposed it was indeed there. It seems logical to conclude there has been some lowering of jitter here.


And then we come to the ethernet filter. I suppose audiophile switches can be considered as one, then we have actual filters such as Network Acoustics Muon, my JCAT Net XE and others. I continue to believe these necessary even with the all measures above.


Optical conversion is also valid approach post router. While I found generic FMC somewhat effective, at this point I prefer ethernet. On the other hand I've not yet tried optimizing a fiber solution, for example two Sonore OpticalModules, both powered by lps, further upgraded with Finisar optical transceivers.


Assuming one has high resolving audio and streaming systems the above network optimizations should provide for substantial sound quality improvements. In my system, perception of performers in room has been taken to a new level of intimacy, meaning a more emotional connection to the performers and performance.


At this point, I consider network has been fully optimized, the only upgrade I'm aware of would be ISP upgrade to 1gb.


@debjit_g To clarify, what you said is what I meant to say.

Vertere HB ethernet reduces noise and is analog sounding.

Very transparent speaker cables will reveal any noise in your system or streaming setup.

I personally find there are many places where noise can be injected in a streaming setup.

@sns or anyone else

HELP.  I am functionally blind and reading long threads is extremely hard for me.  I am also not a computer / digital expert.  This is a great thread and one that is really timely for me.  So, there are too many suggestions and I am unable to try them all out.  I am super happy with my sound and wonder what people mean by noise in the system ( sorry).  What in particular is the noise that you hear when listening to music?  

I am intrigued by this discussion and would like your help.  I built my house three years ago.  I have a dedicated 20 amp line into my two-channel room and separate theater room.  I use a Inakustic 3500 power conditioner at the end of the chain.  I have a network closet that is next to my theater room but 50 feet away from my 2-channel area.  The whole house network includes an Araknis 310 Router and 210 Switch tied to a Netgear C1000 modem and an Audioquest 1200 power conditioner.  I ran fiber and cat 6 from the Araknis to my two-channel area.  

My audio components are Lucas Audio LDMS Music server (imo just below Taiko) and a Lampi Horizon DAC.  The rest is not important to this discussion.  I have been using Fiber for my LDMS.  However, I am getting an upgraded LDMS and Lucas has suggested I go back to Cat 6 Ethernet.  

Even though I do not know what noise I am supposed to hear, I am intrigued by wanting to improve my audio experience.  I have been doing some research and this is what has been recommended to me.

Option 1

TeddyPardo LPS 12V / 2amp that would connect to my Netgear modem.  I was surprised when that was recommended.  I thought it would be connected to the Araknis Router and Switch.  Apparently the Araknis is already a good home network solution, 

Paul Pang Quad Switch.  This would be attached to the source wall Cat 6 cable.  I would then need to identify an Ethernet cable to go from the Paul Pang Quad to the LDMS.  

Option 2

EdisCreations -  Hong Kong

12V 6amp EdisCreation LPS Extreme

Silent Switch OCXO Extreme version

And then if I really want the best, I would add their Fiber Box which goes before the Silent Switch.  They are also recommending their silver LAN ethernet cable.  

Am I missing anything?  Is there anything else I should be looking at or considering?  No one to my knowledge has mentioned these LPS or switches in this thread so if possible you may want to check out their websites.  

I really would appreciate your feedback and if you want to private email to not clutter this thread please do.  

P.S. what got me started on this topic as I am having major buffering and freezing issues with my TVs and even in my theater room.  .  Everything is streamed through Roku.  I can not figure out why I have to always reboot the system.  The Cable company said their system is fine and the Araknis is totally up to date.  I have no issues with music buffering.  

Thank you

I would go with Option 2 - EdisCreations Silent Switch OCXO Extreme version switch and Fiber Box II before your LDMS server. Use a generic LAN cable like LinkUp from Amazon between your wall plate to Fiber Box and then to your switch. I subscribe to everything matters philosophy but in this case the last LAN cable between switch and LDMS matters the most, So check out Network Acoustics Muon Pro LAN cable. If you decided to get both Ediscreation switch and Fiber Box II, I would experiment with placement; wall to switch then fiber box to LDMS or wall to fiber box then switch to LDMS. Here are the links to Ethernet cables,
