Every element of the NW-ZX300 has been engineered for master-quality sound. Enjoy music exactly as the artist intended, anywhere you choose. Experience digital music to the fullest with High-Resolution Audio. By capturing music at a higher rate than CD, increasing both audio samples per second and the bitrate accuracy of each sample, High-Resolution Audio offers an uncompromised rendition of an artist's music. Savor every breath and subtle movement for a truly emotional experience. Enjoy studio-quality sound, thanks to the Direct Stream Digital (DSD) audio codec-designed specifically for High-Resolution Audio. This 1 bit format operates at a far higher frequency than conventional PCM digital audio, resulting in a more natural, and intensely detailed sound. The result is clearer, crisper, High-Resolution Audio quality. Enjoy a High-Resolution Audio experience with the S-Master HX™ digital amplifier. Using a simplified and fully digital signal path, S-Master HX™ reproduces the subtleties and wide frequency range of high resolution formats. Unlike conventional amplifiers, it maintains the digital signal until right before the speaker output, eliminating distortion - for High-Resolution Audio, just as the artist intended. A rigid aluminum milled frame provides strong resistance to electrical noise for clear, stable sound. Go beyond CD quality. DSEE HX™ builds on our proprietary DSEE™ technology, upscaling compressed audio files to a level that's closer to High-Resolution Audio. By restoring the subtleties of the original recording that are lost during the compression process, DSEE HX™ delivers a rich, studio-quality audio experience for all your music. The NW-ZX300 Walkman features a balanced standard plug, designed for the new 0.17"balanced connection cable. This supplies compatible headphones with fully discrete left and right channels, unlike conventional headphones that share a ground wire. The result is far better external noise suppression and improved stereo imaging, as well as more headroom for powerful sound delivery. Higher-quality film capacitors contribute to more efficient circuit-board design and better sound quality. These film capacitors also supply voltage with a linear response across frequencies, resulting in reduced distortion and noise on everything you listen to. We spent 3 years developing the FT CAP with a singular focus on delivering powerful sound. Its large capacity means it can deliver reliable and clean voltage. This ensures well-defined and immensely powerful bass notes are delivered to the headphone output.
