So basically the recommendation seems to be getting the Schiit Hel and a good pair of stereo headphones. Is this going to be much better than onboard audio? I have 2.0 speakers but want to sometimes plug a headset in for gaming. I play Fortnite and need something that is good for in game positional audio(footsteps)
Technically no. How precise the positioning is depends on how well the HRTF is suited to you but the variances in human head shape and composition are small enough that most HRTFs built into games or the one built into Windows 10 (Windows Sonic for Headphones) are more than good enough.
Better performing DACs, ADCs, and amplifiers only provide you with a lower noise floor ("blacker background"). Onboard audio will usually have the ideal flat frequency response but will tend to have a relatively high noise floor which can result in the quiet backgrond static/hissing sound when nothing is playing.
Good audio doesn't magically make things sound "better." It only makes thing sound cleaner.
Most people should just get the $8-9 Apple USB-C to 3.5mm headphone adapter. It destroys basically everything south of $150-$200 and is already audibly transparent with a SINAD of 99dB on the DAC + amp stages combined (you need a 96dB SINAD for normal listening conditions and 120dB for extreme listening conditions as well, like sitting in some anechoic chamber. Higher SINADs will result in imperceptible changes so it's really just a better circuit on paper and nothing else). If you're going to be driving high impedance or low sensitivity headphones, maybe the Schiit Hel. Next "upgrade" would be the Khadas Tone Board, Schiit Modi 3, or Topping D30 as the DAC combined with the JDS Labs Element, Schiit Magni Heresy, or Geshelli Labs Archel2 Pro for the headphone amp (or stereo speaker preamp. I don't follow power amplifiers but you won't need one if you get something like the Yamaha HS5/7/8).
For most people I just recommend the Apple USB-C to 3.5mm adapter + Audio-Technica ATH-AD900x (or Sennheisers HD598 if you prefer that sound) and the Monoprice USB-C female to USB-A male adapter if don't have a USB-C port. The ATH-AD900x usually drops to $100 so the total setup costs around $120. If you need a mic, get something like the antlion modmic clones or the samson go mic.
