You are correct on noise coming into house, however self generated noise and jitter from modem on still exist in all streaming setups. Whether you need a filter or not is for you to discover via experimentation. I've done much experimentation with streaming setups over the years, sometimes there is progress other times regression, and sometimes change is just change. Streaming can be as simple or complex as we choose it to be, curiosity certainly has hold on me!
the question of changing ethernet cables
Hi everyone, I am also new to the site and I have followed many conversations learning much. I have ethernet cables running from the router to the streamer (PS Audio). However, I have a fiberglass cable running from the street input to my main box. That should mean from what I have followed here that I am not bringing any noise into the system from outside. I too, have thought about changing the internal cables and/or employing an isolator of sorts. However, in my case, I am not sure that I need to. Any suggestions would be welcome.

@finnlove Believe you're speaking of Small Green Computer, specialize in optical steaming. I do use Sonore OpticalModule and OpticalRendu, many experiments with optical in past and continuing into future, some in next few weeks. With optical you can go with generic or Sonore FMC in which case you could go full optical from ISP through streamer, this may or may not beat any ethernet solution, hard to say, implementation is key.
Now, if you had optical capable router and all Sonore optical, fully optimized this could be very nice setup, full galvanic isolation from wifi or any other noise. You would still have issue of wifi directly injected into router motherboard which cannot be elimated by any means other than turning off wifi on router. I bet you'd have pretty nice setup going this direction, I'd at least try if I had optical via ISP.
Keep in mind optical not so easy as install and forget, subject to optimizations and improvements just as any ethernet setup. I won't go into it here, but suffice to say Sonore equipment superior to the generic FMC. My further upgrades, already in house will come in due course. |
@finnlove Any dimmers/reostats anywhere in house can cause these sorts of hissing/fuzzy sounds. Even with dedicated circuits on audio these can infect, transformers with LED lights can also infect, I know both from personal experience.
Otherwise most likely culprit tube amps, pre's. Doubtful SS equipment would cause this. I've never heard any hiss noise emanating from various routers or modems with or without lps, still, who knows whats possible with these streaming setups. Connecting directly to fuse box like you have may actually increase susceptibility to noise.
In regard to possible router noise, just a couple days ago installed Netgear XR1000 router, this for lower ping time/latency/jitter vs previous Netgear R7000. So new Netgear now direct feed from modem, also now only feeds streamer, NAS and R7000. XR1000 wifi now turned off, R7000 feeds all wifi in house. Point is to get all wifi with it's extremely high levels of emi/rfi completely out of streaming chain. So now I have optimized my entire chain feeding streamer, best modem possible for my particular ISP, all wifi off system with high quality router, ethernet filtering/clocking via JCAT Net Card XE, quality cabling via all AQ Vodka post modem, everything running off high quality LPS. All upgrades prior to latest wifi isolation have been effective in lowering noise floor and more analog like sound via lower jitter. This weekends listening sessions will determine the effectiveness of new router and wifi elimination from streaming chain.
