I never tried the Sub 37 but I saw a comparison of the triangle - waves on Youtube ( between the DOM 1 and the SUB 37 ) - and it claerly showed that the pure triangle of the SUB is softer ( rounded at the top ). Maybe this explains the muddyer sound ?? ( I have no expériences with MOOG ) .
I never found a clip that compares waves of the different Moogs .
I still hope for a " Maxitauer " to come out some day ( = all controls external ) . I would have bougth a Minitaur alltready if all parameters had buttons or knobs
