Effect of Internet Service Quality on Streaming?

Does the issue occur with vinyl or just digital.

Do you have a CD player to try?

You should have a dedicated modem and a dedicated router.  A duel use modem/router is not as good.

You should have a filter at your data demarcation powering your modem, router and switch.

A significant amount of RF penetrates through the equipment chassis itself.  A significant amount enters through vinyl.

Neither of these paths can be managed with a power line filter.  Its up to the manufacturer of the equipment to create a power supply that filters the RF before penetrating the power supply.  But, a over filtered power supply can sound flat and lifeless.  This is especially true with a phono preamp.

I tried the puritan ground box.  It did nothing in my system.  But the dealer that sent it to me doesn't even use it.  He uses CAD.  What I am saying is a good ground box may help.  But your going to need at least 2.  One for chassis and one for signal.  Then you need a bunch of cables.  A good ground box solution is generally around $7k to $15K in equipment.

Erik, I note your comment that you can increase the buffer size for Roon.  Can you point me in that direction?  I had lots of issues with HiRes over a mesh network. The system is now wired but I still occasionally have stoppages that i suspect are related to buffering.    Thanks, Mike

Linear power supplies on router, as well as your switch 

jcat Ethernet reference Ethernet cables more natural then the AQ Diamond 

i own one put the Jcat as your end point , and digital power cords which have extra screening . 

Thanks All, lots of ideas and as I mentioned I’ve been dealing with this issue for a few years now, with numerous changes to my system during that period.

Lots of great ideas to improve my upstream network to consider. That said, while these ideas may improve my system, I am doubtful they will resolve my occasional extreme quality dips. Because, like others have said in this thread, I think it must be a power issue as opposed to network. I started this thread hoping maybe I did have a network issue as I think that sort of issue would have a better shot at being solvable.

I’ve experienced a few dips since starting this thread, but not as extreme as last Friday evening. During the recent dips, I did try to see if the gap between the local and streamed file widened, but it did not - they both seemed slightly degraded which again points to power - or possibly RF noise - being the culprit…

Maybe grounding boxes will help, but that would be an expensive shot in the dark to hope it’s the solution! I’ll keep trying things.
