My system configuration is as follows...
I have a home gigabit network using both wired (ethernet) and wireless connections. Router is an ASUS RT-AC68P. The main network switch is a TP-LINK TL-SG1016D. Ethernet wiring is Cat 5.
The core of the music system is a CAPS v4 Cortes:

The OS is Win 7 Pro x64. MC21 runs on this machine, which functions as a library server, a DLNA server, and which also stores the music files.
The Auralic Aries is currently connected to the network wirelessly using the 5GHz band, but has been at times connected via ethernet. Either type of connection works fine.
The Aries USB output is connected to a Vinnie Rossi LIO DAC USB input.
Playback on this system works well the vast majority of the time for music of every resolution I have - from mp3 up to DSD64. The only glitch I've noticed is that convolution breaks gapless playback.

Here are a few suggestions for troubleshooting the audio dropouts.
Make sure you have the latest firmware on the Aries.
Try playing music to the Aries from MC without JRemote or Lightning DS. I doubt this will make a difference, but it may eliminate JRemote or Lightning DS as the source of the problem.
Set your Windows Power Management to High Performance. If that makes a difference, it could be you're getting some extra latency due to the CPU being throttled.
Try putting some music on your PC hard drive and import it into MC. Play those local tracks to the Aries. If playback works smoothly, the problem may be latency reading music files on the NAS.
Try setting your DNLA server Audio Mode to
specified output format and Audio Format to
low bandwidth mp3. Restart MC (and wait for MC to find the Aries).
This will decrease the network bandwidth required to stream music to the Aries. If playback works smoothly in this configuration, the problem may be your network bandwidth (speed).
If none of these steps yield any insight into the problem, I'll have to punt to the more knowledgeable forum members.

I can't address the TIDAL issue, as I don't use that service.
Again, good luck!
