SINAD: Signal-to-Noise and Distortion RatioThe Key to Pure Audio Output
SINAD is the ratio of the useful signal (a standard lkHz sine wave) tothe sum of noise (such as circuit noise floor) and distortion signals(such as harmonic distortion, intermodulation distortion, etc.). lt isa critical metric for assessing the purity of the output signal fromDAC dongles. The higher the SlNAD value, the greater the proportionof the useful signal, and the less noise and distortion -resulting incleaner sound quality and higher fidelity.

Power output & Drive Compatibility forDifferent Headphone lmpedances
OUTPUT POWER IS A CORE PARAMETER MEASURING THE DRIVING CAPABILITY OFA DAC DONGLE. IT REFERS TO THE EFFECTIVE OUTPUT POWER DELIVERED WHENDRIVING HEADPHONES OF DIFFERENT IMPEDANCES (SUCH AS 16Q, 32Q, OR 300Q)THIS METRIC DIRECTLY REFLECTS THE DONGLE'S DRIVE COMPATIBILITYWITHVARIOUS HEADPHONE IMPEDANCES, PROVIDING CRITICAL REFERENCE FORMATCHING EQUIPMENT WITH HEADPHONES
