A review of the D'Angelo-model appeared in issue 6/00 of„Akustik Gitarre".
Wolfgang Niemann concludes
»Sonntag's D'Angelo may align itself in the rather small competition of first-class acoustic archtops that are made of massive wood. At a price-point that can be called worth the money one gets an instrument, which was built with a craftman's skill from best materials that offers a pure joyous playing experience.«
