Weiss DAC 204 hiccups

Thank you.  I will try that before looking at higher quality streamers.  

What sort of hiccups are you experiencing? I have a Weiss 204 and am using a Bluesound Node as the streamer and also had some issues for a while (some random noise issues that were very intermittent for instance). I tried a number of different troubleshooting options, including swapping out another 204 from the dealer. What finally solved my issue, after several different ways of connecting to the Weiss was adding an iFi USB ground defender with one of their power supplies. This may have been very system dependent, but eliminating the 5v USB power from the Bluesound and addling it back with a much cleaner PS fixed the issue that took me some months to figure out.

I even had my own “hiccup” issues via an AQ SPDIF (coax) cable. I never truly understood the root cause, but glad that the cleaner USB power resolved the issue.

I agree with the recommendation to add a router extender.  I had the same issue with my separate streamer and DAC.  I purchased a Eero 6+ extender after the one extender I got from my wi-fi provider stopped working.  The technician from the provider recommended it over their own extender.  I run an Ethernet cable from the Eero to my streamer.  Drop out problems solved.  

Thank you for these additional suggestions.   

For clarity, the "hiccup" I am encountering happens once or twice during every few songs.  It is more of a stutter/momentary skip.  Very noticeable.  Last night, I decided to play CDs from an old Cary 306/200 using the Weiss DAC and I encountered no problems with this issue.    

Sounds like a bad digital cable. Or a clock in the BS Node is malfunctioning.
The network stream is buffered in the BS Node so it would have to be an outage of more than 30 seconds. Try Toslink or another digital cable or even an RCA cable. Even if cd player used as transport doesn’t suffer from the same problem it could still be a cable. But to rule out wifi issues you can run a speed test on your phone when you’re next to bs node. Make sure you’re on the same network. Let us know what speed you get on a download.
