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…

@nyev Have you considering running your system on batteries?   I have an Ecoflow Delta 2 Max and a Growatt 1300, (both are lithium iron phosphate with pure sine wave inverters) and I can run my system on them for over 24 hours before recharging.  

@tonnesen that is a very interesting option (running off of batteries).  Are there any downsides to the SQ vs other more traditional alternatives?  

I did read a report from a fellow Audiogoner who had much experience with conditioners before going to a Stromtank - which is a very, very expensive solution.  But even that he mentioned in a post that he felt there was some loss of dynamics.

@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. 

@audphile1 , I used to have the amp plugged into the PSM156 but have been running it into the wall directly for some time now, in a dedicated 20A line.  While I prefer it plugged into the wall, I didn’t actually experience any loss of dynamics, end like now, the sound quality would occasionally dip very low.  As I mentioned I’ve tried a number of conditioners none of which helped with this issue.

I tried the battery experiment for one day, and I should try it again for a longer period and with different amps - but I was not aware of a change in sound quality.  I was using my AGD Duet amps that draw about 13 watts each while listening to music, so they were well below the capacity of the EcoFlow battery  (1800w, Surge 3400w).   In any case, it's good to know I can still listen to music during power outages.
