Latency over digital links is no issue. Even A/D and D/A conversion times are very low. Much higher is RTL over USB which becomes very high with bigger (asio or other) buffersizes.

I do not find a product with that name that has aes inputs, can you please link it? I only found a monitor controller when doing Google search. Therefore I am not 100% sure about the intended use cases.

But if its all about DA conversion why not relying on the quality and features of ADI-2 Pro FS R BE?

The last weeks we had some discussions about DACs and that there is merely a noticeably between different DAC chips more important a perfect design and good features and here RME designed a masterpiece of device.

You can be sure that steadyclock fs removes any clock jitter between ufx and adi-2 pro regardless of what digital i/o you will use the clock signal will be refreshed and d/a conversion in the adi-2 pro will be performed by using it's internal fs clock.
Other advantage to you is the auto reflevel feature which uses automatically one of the four reference levels to maximise snr and dynamic over a wider volume range.
The bittest supports you to check for lossless audio transport end to end from player up to the adi. The driver allows you to check for any potential crc errors during usb transport.
The state overview display will support you troubleshooting digital connections.

See my blog articles about features and integration of adi-2 pro fs into your environment.

A list of  useful features which are unique to this device:
- excellent ad da conversion
- support of four reference levels and a feature called auto reflevel that automatically chooses the optimum reference level so that SNR and dynamic is optimum over a much wider volume range (honours also B/T, PEQ and dynamic loudness settings in the calculation to select optimum reflevel)
- ear protection by slow ramp-up of volume when plugging phones or switching between monitors and phones
- bittest to be able to perform an end to end test whether audio from a PC player was received lossless to ensure/check highest quality playback
- 5 band PEQ to compensate deficits of phones or hearing weakness, even  possible per channel
- B/T controls to compensate bass and treble for bigger differences in music material/masters
- dynamic loudness so that music keeps it's body if you turn down the volume
- support for DAD in case you want/need it
- different levels of crossfeed
- extreme power headphones outputs driving even phones that need a lot of power
- balanced mode for phones in case you want it
- useful status screens with the possibility to troubleshoot digital connections better
- SRC (sample rate converter) to connect devices with fix clock like DAT recorder
- two dac chips to connect and compare phones at the same type of da converter
- can act as a monitor controller for your monitoring section finalising the end volume  so that a 0dB fader setting in TM FX can not harm your ears and/or equipment just in case you performed no proper level matching eg using attenuators if needed.
- possibility to choose between different DA filter of your DAC for eg either most linear frequency courve or to use have an emphasis on other things of a little bit higher separation of certain percussive music instruments. These are only nuances and might depend on your room, equipment, etc (see one of KaiS's postings).
