I have done a dozen diy amps, from the O2 to the neweer TI OP1622 chips in a very small package...805 parts were not that bad to hand solder,
but the leadless QFN package with 0.5 mm pitch were a different story...had to buy a hot air gun station and learn to how air solder.
The chips get really hot when doing this especially when there is a heat sink pad to solder to on the bottom of the part!!
This DIY project worked first time!! But I dont think I will do another one in the near future..
I would think Schitt has his vendors wave solder or oven solder vs the slow hand approach in this new small parts world...diy days may be numered!
