Superior Audio Technology
Yamaha’s relentless pursuit of sonic purity is clearly evident in the engineering of the WXA-50. The preamp circuitry uses the same high-performance ESS Digital-to-Analog Converter (DAC) found in high-end Yamaha AV receivers and a proprietary power supply ground configuration prevents sound degradation. A 48-bit digital volume control provides much greater precision and quality than conventional controls. A highly-rigid metal chassis supplies the stability necessary for clear, powerful music reproduction.
The WXA-50 supports high-resolution audio –including FLAC/WAV/AIFF up to 192 kHz/24-bit, Apple Lossless (ALAC) up to 96 kHz/24-bit and DSD up to 5.6 MHz – for more accurate reproduction of sonic details, presence and atmosphere.
