Effect of Internet Service Quality on Streaming?


I’ve struggled for a long time with sound getting much, much worse around dinner time, and in some rare cases I don’t get depth, clarity, dynamics and imaging back until around midnight. Like many people I’ve attributed this to noise on my AC lines. But recently I’ve been wondering if maybe internet service quality is at least contributing to the issue in some manner. When I run tests it appears that speed, jitter, and latency are all higher at times when the sound is poor. That got me wondering if anyone knows whether one type of internet service is better than another for HiFi streaming? For example, is ADSL or DSL better, or does it matter? And what about speed? Particularly interested in anyone who has real world experiences from experimenting in this area…

Sure.

I like to relax and listen to music on holidays.  Few years ago, my internet stopped working for a whole day on Labor Day.  Way to go Spectrum!

Glad I had my vinyl and CDs.

I suggest you ask your Internet service provider to check the signal frequently response and all the cable connections in your home. My frequency response was too high and he replaced all my inside connections.  He also corrected and rewired the cables in my outside box.  

My immediate reaction was, it’s your streamer. Then I looked at your streamer. I had a Grimm in my system for a while. It sounded very good, definitely worth the money. Sonically it was not quite as good as mine… but it was much less expensive.

But thinking about your problem. I put a very high probability that it is that your streamer cannot cope with either your power or internet connection. Aurender streamers get very heavy as the go up in performance. The Grimm is very light weight… indicating to me it is lacking massive electrical and vibration isolation. That would account for it sounding good in my system and yours when power and the internet is quiet. The Aurrender has massive electrical isolation from outside and cashing to make up for bad internet performance. My streamer sounds exactly the same at all times. While there is a very slight increase in system performance late at night… it is the whole system related to the power grid.

 

 

I recommend borrowing a Aurender W20SE. I bet the problem goes away. I would think even an Aurender N20 will significantly if not completely mitigate the problem.

Thanks all. @ghdprentice i wish it were my streamer. My streamer/server is actually an Innuos Zenith Mk3, feeding a PhoenixUSB reclocker (went back from the Grimm in the end). I had the same swings in sound quality with both products - no difference whatsoever on that front.  I also briefly owned an Aurender N20 and the problem also remained.

I will try comparing local files vs streamed when the SQ goes south next (it is great right now).

I live in a quiet, treed area with space between houses and very limited traffic, and even when there are no household ambient sounds I still get poor sound that peaks around dinner time.

I actually do have fibre service, at 500Mbps (worth getting faster service?).

Yesterday I did test latency and jitter, using the online fusion network speed test tool. Latency and jitter readings were absolutely higher during the period my system was sounding worse. But, I’d assume that maybe AC was also noisier during this “peak demand” time.

@hgeifman Thanks I will look into “signal frequency response”. Haven’t heard of that before..

System is back to sounding incredible right now. But after dinner last night was about the worst I’ve ever heard it! Muffled, compressed, no higher frequencies coming through, loss of dynamics, overall dull.

Related question - does anyone know if Class D amplifiers are supposed to be more immune to AC noise?  I’m considering some changes to my system and a possibility is that I could move to the Mola Mola amplifiers.  I am aware of the general pros and cons of Class D but not sure if they are more immune to environmental noise.  Guessing not but it crossed my mind as a possible solution.
