Outstanding quality.
Not my first headphone amp but certainly the best ive heard, combined with decent iems or studio headphones.. it is a revelation to listen to known tracks and hear the soundstage is increased, along with definition.
This amp will not colour the music unless you engage the bass boost and then the bass increase is subtle and placed in the bandwith that isnt sub low, more mid to hi low and adds a pleasing depth.
In low gain with bass boost off, its incredible with in ears, with hi gain and bass boost on, studio monitors are driven better to project perfectly.
