Hi most of the Tidal issues have been down to duplex latency ... That is round trip time between the streamer , Tidal media server and streamer again . This can vary under load from the Tidal (or any server) as well load on the network route. The current firmwares are quite sensitive to this, however the firmwares that are in development for the streamers are more tolerant to latency here... and dropouts will be significantly improved.
This issue is not directly related to network bandwidth other than in extreme scenarios of congestion. RTD (round trip delay) is a normal TCP/IP network characteristic, and in short the clients need to be able to tolerate it over the typical operating environment with the supported applications. Typically you can mitigate RTD by having larger TCP window segmentation memory and/or well as having larger amounts of application buffer memory and/or improving the speed and efficiency of the client TCP/IP state machine responsiveness of the client.. I believe Naim ate focussing on the latter. The two former options tend to increase application delay and latency.
