He really is good, I agree. The word that springs to mind as I listen to him playing is "purity."
His BWV 1003 Allegro is also really good.
I remember back in the e-borneo forum days (late 1990s early 2000s) that Patrick Mailloux (the luthier of his 8-string in that video you posted) was just getting started making guitars. Congrats to him for his success.
