Let me start by apolgizing for how long this got lol...
So, just clarifying your last comment a bit with OOYH sounding hollow and/or to way back(i.e. distant and non distinct?) as well as using headphones the majority of the time.
Listening over headphones is for the most part incredibly clean and natural due to the lack of room reflections, so when directly comparing normal headphone listening to OOYH, the room reflections, especially when not well rendered, sound strange. Initially you could do most of your comparisons with the Genelec preset as thats a treated recording studio, and Waves NX with the room ambience(what did you have this set to?) lower you get somewhat externalized sound but very clear and non reverby.
Even after upgrading headphones, dac/amp, and adding conditioning, OOYH is still going to sound way more like loudspeakers than headphones and some of the presets sound like giant speakers in a giant room and everything needs to be perfect to be able to turn the volume up loud enough or it sounds like a mess(this is where the eq comes into play as well, allowing you to turn the volume up to your normal listening levels, as well volume matching is very important for comparisons), but as everythings upgraded the hollow and nondistinct sound slips away and becomes very full and natural sounding, due to the equipment rendering all of the reflections with perfect timing.
I use the Genelecs most of the time because the music I listen to is a distorted mess and doesnt play nice with alot of the other presets, but anything that ive tried with other music, pink floyd, classical, etc. i can go through all the presets and enjoy the uniqueness of each speaker system, its eerily lifelike. Ill also use the magico q3s to warm up certain content, the ribbons to brighten up some, the Cello for older 80s movies that were mixed for more reverberant auditoriums.

Not at the momemnt but it may be included in the next firmware, I have an old beta version that has 3d off so Im not sure what the issue is. But I never use it, the head tracking increases externalization its pretty cool xD

yes it will charge over usb while in use, but there were alot of reports of it draining the battery when plugged into usb overnight. I only use mine over bluetooth so i don't have experience with that. The headfi thread might be more informative.

No I wouldnt get the Mobius to use with OOYH
Its tough to say a minimum for ooyh as it scales right up with several thousand dollar hifi rigs.
First thing would be planar drivers, a massdrop hifiman he4xx or he400i, a used audeze el8. Switch them to the dekoni lcd velour pads for smoother treble and a bigger soundstage. And isolating an inexpensive dac/amp with an optical connection and powering it with a cheap jameco regulated linear power supply. Thats just $30 for the dac and psu and will yield good results until you spend over $300.
for that specific model youd need a dc male to microusb adapter as well.
or with a bit more power https://www.amazon.com/dp/B00A2QLPJM..._QiuXCb6V6YF34
For the dac/amp you want ultra clean, ultra regulated, high power output, lots of reserve power, class a, discrete, dc coupled amplifiers, and upgraded low jitter low phase noise clocks(TCXO) and the Audio gd equipment being in current signal with less stages(shorter signal path), non feedback with its 0 delay, balanced equipment with 0 crosstalk(with all the other benefits of balanced circuits). Using OOYH makes all the differences between these components much more obvious than when not using it due to the massive amount of extra detail and critical timing required by the program.
Compare the audioengine d1 to what my personal minimum would be, the audio-gd nfb11. The D1 is a small bus powered dac/amp, that means all the leakage currents from the pcs switch mode power supply, the poor output impedance of that power, and any other noise generated by the pc, with the nfb11 over usb the signal is still just as contaminated by the pc but at least its self powered, and very well self powered with discrete double stage power supply units, clean, fast power.
So you could use optical but thats bandwidth limited and you lose alot of the extra detail that OOYH provides with its measured reflections. So I use an uptone iso regen to isolate and regenate the usb signal, this is much more detailed than optical. Its also significantly cleaner and less fatiguing than not using it and having the pc connected to the nfb11s usb. But the stock smps with the iso regen was also somewhat fatiguing and made me want to roll off treble a few dbs, switching to the cheap $10 linear power supply from jameco helped, but adding an uptone ultracap lps was another increase in detail, the size and clarity of the image, its suprising really that just the power supply for the iso regen could be so noticeable. Further still adding a star quad(quadrapole) dc power cable between the iso regen and ultracap lps removed another layer of noise generated by a voltage developed across the inductance of the cable due to the varied current draw of digital signals that cant be dealt by with components regulators. That ones always a real suprise when you add it, a little $5 self made cable or $30 ordered from china and its such a boost in clarity.
So the above comparisons with optical and usb were done with the nfb11 and already using a Topaz 91092-12(bought used for under 40-80) for ac line conditioning. In my first system with the nfb7 and 1amp, after adding the iso regen with ultracap and star quad cable, I was watching a 7.1 movie ran through OOYH and a scene with a waterfall was intensely detailed but was still very fatiguing.  Adding the topaz cleaned up the ac power making the waterfall sound very natural and the presentation became completely non fatiguing. These units supress line noise by way of an ultra low interwinding capacitance isolation transformer with multiple internal shields, and a floated neutral secondary.  About 140db common mode noise and 60db traverse mode.  as well as providing some surge suppression.  And this allows for conditioning with unfiltered distribution after the transformer so any connected electrical devices have very low impedance between them minimizing any noise generated by leakage currents.
So you see why its tough to make a recommendation, each component is more capable, or removes another layer of noise, and further improves the performance of OOYH, but it gets expensive and it gets complicated. All I can do is share my experiences and upgrade path.
But my minimum recommendations are:
-Start with the cheap optical dac and linear power supply and a pair of planar magnetic headphones.
-Upgrade to the Audio-GD NFB-11 with TCXO via optical
switch to usb with conditioning:
-Uptone ISO Regen, powered by a Jameco 9v Regulated LPS or Uptone Ultracap LPS(the first version you can get used for about (250) with a star quad dc cable(make it yourself for $5 or order one for $30)
and power conditioning:
As well as a star quad powe cable for the nfb11 or other dac, make one yourself, order one ffrom atlhifi or the best would be vh audios flavor 4, but this is the same situation as the dc power cable, digital devices work very well with these types of cables and i didnt notice any differences when trying various other cables like you do with power amplifiers, i.e. 10/3 cryo vs $5 14/3
The NFB11, compared to the d1 and other cheaper options, in addition to the power supplies, keeps the signal in the current domain after the ess9028 dac chip, and uses no feedback class a discrete dc coupled amplifiers, no opamps, an extremely short uncolored signal path, perfectly regulated, excellent for using with OOYH. You may see that these units dont do well with certain measurements and thats due to the non feedback amplifiers dont do well under torture tests but other measurements will show them perform excellent under normal listening conditions. Look at it like supersampling a uhd hdr video stream, youll get about 1fps but you'd never watch it under those conditions and you cant tell a difference between the native video.
Going up from there, the nfb7 and nfb1amp takes that ultra clean image from all the conditioning and makes it gigantic. The fully balanced drive, additional stages of regulation and massive power supplies really renders every single detail from the measured room impulse responses and binaural rendering perfectly. Its absolutely stunning at this point. The size of the virtual room, the accuracy of sound effects placed in the room, the fidelity and clarity of the image, anyone I have listen to this system(or watch a movie with) takes off the headphones, looks around the room puzzled, looks at me like im an *******, puts the headphones back on and their jaw drops. Colorful adjectives aside, this does happen with the nfb11 setup as well but ya know... dramatic effect.
I listened to alot of components under 1000 and audio gd performed well above the rest. And like with everything it depends how much you want to spend and things scale up the more you spend.
The last thing is the bass shaker system. This really helps with the externalization because when youre listening to something thats supposed to feel like youre in a room with speakers and you have all this 20hz sub bass only on your ears. Well placed on the frame of a chair and the shakers blend seemlessly with the headphones and its a very close approximation of an actual subwoofer system, while of course you dont feel the actual room being pressurized the special effects and sub bass are accurate, tactile, and immersive.
