Perhaps the most important feature of NOIRE XO is the addition of DCA’s critically-acclaimed AMTS tuning system, previously found only in our top-of-the-line Stealth, Expanse, E3 and Corina headphones.
Truly a revolution in acoustic engineering, AMTS uses advanced metamaterial design concepts to shape system frequency response while simultaneously eliminating high-frequency standing waves, which are responsible for the synthetic-sounding high frequencies found in all too many headphones.
By eliminating these standing waves, NOIRE XO with AMTS delivers remarkably balanced, nuanced, and airy treble free of the fatiguing artifacts that diminish your listening experience.
