What other streaming services do you recommend besides Tidal?

I will likely still consider my options once speed is resolved anyway.
May give Spotify a trial and possibly Quboz once launched here...cannot stand Jay-z......lol

FWIW - using Tidal and Spotify (premium/hifi subscriptions to both).  
SQ with Tidal is better but I also experience periodic buffering dropouts, esp. late at night though rarely during the day.  Never happens with Spotify.  Am paying for Blast Xfinity high speed internet service.  SQ with Spotify is NOT terrible - just not as "vibrant" as with Tidal.  Spotify library is definitely superior to Tidal and I like the interface better.  The Browse/Discover function from Spotify is a great way to discover new music.  BTW for all the Tidal fans, it was interesting to me to see that not all Tidal streamed music is uncompressed.  While much (most?) of it is (as witnessed by the Aries Mini/DS Lightning file data display) I do notice the occasional AAC file; e.g., Joe Bonamassa's "Blues Deluxe".  Still sounds very very good.

Knew it was not just me, remember a thread on it last year.
And same symptoms , late at night, never during the day.
Hopefully the new modem will help but going to check Spotify out as well, like to keep my options open....

@uberwaltz, Congratulations.  You are making good progress.  After AT&T installs the new modem, please ask them to run a speed test to confirm your speed is 75mbps.   They should also confirm the cable signal strength is in the correct range.   Please ask them to check your cable from from the wall to your modem and also your cable box outside.   My Technician replaced the ends of my cable and rewired my inside wall box.

The speed and the cable signal test confirm the down stream components are working to specifications.   My signal strength was out of the acceptable range and my neighborhood also had downstream components that were not up to spec.  I suggest you ask the AT&T Technician to check everything else (this is what I did). The cable junction box near the street was corroded and was replaced.  My cable work required an inside Technician and an outside Technician to complete this work.   

I forgot something above.  I suggest you re-boot your cable box and router around once per month.  Unplug these devices for two minutes and re-start.  It seems, that over time, these units need to be cleaned out.  

And, after about one week, run the speed test again to confirm your service is 75mbps.  Please keep us posted.  

It all depends on what device is used for streaming. Even with the higher speed, buffering can still be in play. I get 100Mb/s on average and sometimes even up to 200 Mb/s and sometimes get the hiccups when I use my real old windows laptop. Never any issues with Bluesound Node 2 or using my wife’s MacBook Air laptop. In fact, the best performance I get, both sound quality as well as delivery, is playing Masters with the MacBook going through my (non-MQA) DAC.
