WiiM Audio Pro...

...Diverging from the norm of resampling to set sample rate and bit depth, WiiM Pro stands out by delivering unaltered audio up to 192kHz, 24-bit quality. That's the same as an artist's recording in the studio. The advanced TI PCM5121 DAC produces a remarkable 106 dB SNR and an impressive -92dB THD+N performance.
