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…

I think it’s probably 85% power related and 15% ambient noise or something to that effect. Who knows…gremlins everywhere 😂

@nyev my system is plugged into two dedicated circuits. The sound is better after 11pm. Everything is quieter, my family members including my dog are not running around. Sound is fantastic. I tried Ethernet filters (N A Eno streaming system) and it changes the sound yes, but does it filter anything? May be. But it didn’t mitigate the lower performance of my system until that quiet moment after 11pm comes. 
So in my opinion it’s a mix of everything that uses electricity in your house plus people who quit disrupting our listening before midnight. Doubt it’s Ethernet/internet quality. 

@nyev just looked at your system pictures…couple of things you can try, if I may suggest…

1. Raise your cables off the floor. Cable elevators are not expensive. AQ makes decent ones called fog lifters. Lifting the speaker cables, interconnects and power cables off the floor in my system makes an audible difference.

2. try to position your signal cables as far away from power cables as possible or at least don’t lay them down close to one another in parallel - create a 90 degree angle and it should be ok

3. your amplifier is too close to your streaming components. The power supply can be creating an EMI there. I would move the Innuos stuff away from it about a foot at least if possible. I’ve found, in my system with all the amps I ever had that the system sounded its best with the amp on the floor or amp stand and as far away from source components as possible . This will probably minimize the noise your speaker cables may be picking up from the streamer / network components ascwell.

Again, just a thought and is cheap or even free to try.

@nyev absolute killer of a system there dude!
Have you added any acoustic treatments as well?

I’ll just add this for 💩 s and goggles…
I’ve recently compared, once again, CD vs streaming (yes I can’t be helped lol) and throughout the course of this adventure the sound quality definitely goes up late at night for CD and streaming. It’s been the case for me for years, even way before streaming was a thing. But as everyone else here I’m super curious to see you get out of this pickle and tell us how.

@nyev is your amp plugged into the PSM156? Reason I’m asking is, when I had this power conditioner I noticed a very significant reduction in dynamics. I always had the amp plugged into the wall outlet because of it. Even the DAC and preamp were affected. I ended up selling the PSM156 and I have everything plugged into the wall now. I would at least try running the amp directly from the wall for a week or so. See what happens.
