Dual CS43198 DAC Architecture
W4 integrates dual Cirrus Logic CS43198 DAC chips, independently decoding left and right channels. This fully balanced design significantly improves SNR and channel separation, delivering cleaner transients, deeper bass impact, richer vocals, and enhanced spatial imaging.
Femtosecond-Grade Clock Precision
