The ADI-2 DAC has a very nice audio quality. You will have advantages for phones and monitors.
A friend of mine got a ADI-2 Pro and was very exited of it's better D/A conversion quality.
Even with his not so expensive Yamaha near field speakers he said he can hear a difference and he likes it much.
I am enjoying an ADI-2 Pro FS BE (connected to UFX+) in front of my Geithain RL906 / Audeze LCD-3 and I can only say that it's a big win. If you have good recordings you get an amazing presentation of room information in the music material and music details. I have an ADI-2 DAC in front of a high-end HiFi and also there it's a winning team and I can make good use of dynamic loudness or to pimp up Bass by +2 to make some quick general corrections which do not require the PEQ.
With the ADI-2 DAC as a basement you will have the possibility to enrich your sound even further (does not need to be today but on the long run) by getting better phones and/or active monitors.
My friend from internet ordered now even an Audeze LCD-3 in Alcantara, because he found out after a long listening session, that the quality is really superb in this combination and for him this investment was worth it.
Another friend is also just ordering the LCD-3 in Alcantara and the ADI-2 Pro FS BE because after rehearsal he was extremely excited by the sound quality.
With the ADI-2 DAC you can very quickly enjoy some of the other cool featues besides better sound:
- Dynamic Loudness
- remap key feature
- quick Bass/Treble controls for quick adjustments in situations like this: old mix with too few bass, phones which are weak in terms of i.e. bass or to adjust the treble.
- PEQ if you want/need
I wrote this log article that shows, how to integrate the ADI-2 Pro/DAC into a setup: https://www.tonstudio-forum.de/blog/ind … our-Setup/
This other blog article shows my setup playing ADI-2 Pro into the recording and ADI-2 DAC into the HiFi Corner of my room.
It also explains which Windows and Android tools I use for music playback:

Another tip. You can even use a TOSLINK switcher in front of the ADI-2 DAC to make it possible to connect in total 4 devices to the ADI-2 DAC to use the high end D/A conversion not only for your recording interface but also for other devices.
The ADI-2 DAC in my HiFi corner has also TV and Blu-ray player connected to it. Such units also offer a remote control to switch between these up to 4 optical SPDIF sources. Be aware of that these devices might only support up to 96 kHz, like the one from Oehlback (Optosel 4:1) although they claim to support 192 kHz. They equipped the devices with the wrong TOSLINKs inside. If you can live with it you have a nice looking TOSLINK switcher with good working little remote control.
Oehlbach promised to release a revised version supporting 192 kHz, lets see The issue described here (only available in german): https://www.tonstudio-forum.de/blog/ind … lerangabe/
To some of your questions of post #1:
to 5: all that you need is a digital output on your UCX, that is supported by the ADI-2 DAC, in this case i.e. optical SPDIF, which allows you for cable length up to 15m, maybe even 20m. I made a good experience with this cable, I am using several from them (1m, 5m, 15m). This is i.e. the 15m cable: https://www.thomann.de/de/mutec_optisches_kabel_15m.htm
The mutec cable has the advantage not to be too thick, so you can easily lay it around the walls of your room.
And the plug has a tight seat but not too tight to get trouble to plug it in and out. Never had an issue with any of those 10 TOSLINK cables that I have from them.
to 4: I would make the recording interface which is directly connected to your computer to the clock master.
The ADI-2 DAC will then get the clock via optical SPDIF and follow the clock of the recording interface.
It's very practical when you work with a DAW (at least on PC / Windows it's the case) that the DAW sets the sample rate, then the main connected recording interface with TM FX follows this sample rate (in your case the UCX) and the ADI-2 DAC also gets the proper clock. For the final D/A conversion the ADI-2 DAC will use it's internal clock anyway.
