I have a schiit stack, magni + /modi+/ loki. Will This be enough to run hd800s well? Would it be a waste to run these headphones without a higher quality setup?

If an amp/dac measures well at the power level required to drive a headphone to your preferred listening volume without (audible) distortion, it’s enough. Virtually any modern amp released nowadays does this, so if the headphone power calculator that’s been linked here already says that the amp can do it, it can do it. No need for a better (stronger) amp as there is literally nothing left to gain.
problem with it is that it calculates based on 1000Hz impedance, not on highest impedance peak you should be calculating with, HD800s is rated at 430 Ohm at 1000Hz and it uses that number instead of it’s 680 Ohm peak at 93Hz
also some amps low gain modes are done properly, some are just high gain with pre-amp basically, very lazy approach, low gain should be more linear, if your AMP can’t give same amount of power(mW) on lowest impedance drop and highest impedance peak it will change the sound, how much it will change it depends on how big the difference is, all the good sennheiser and beyerdynamic stuff are famous for this, HD800s you might realistically be able to overcome impedance peaks with a powerful amp, but some things just won’t happen like T1 which peaks at 1400Ohm at one point and it will sound different on every amp
tldr:/ I would only consider that calculator to be 100% correct for planar stuff because they have VERY flat impedance curves, very rarely some $1800+ dynamic driver headphones also have flat impedance curves like Sony MDR-Z1R
