Spectra is built to deliver not only portability, but performance. Integrating a DAC, headphone amplifier, and audio switch into one, the ESS 9018Q2C chip performs at a level of -110dB THD+N and +121dB DNR. With patented HyperStream Modulator, Revolver DEM, and patented jitter eliminator, it all adds up to better audio clarity, with improved noise reduction, fewer artifacts, and greater instrument separation. Or to put it simply: Spectra delivers the passion of a live performance as it should be heard.
