Description

The AK4498EQ is a product of AKM’s VELVET SOUND Premium Audio manufacturing process, also used for the flagship AK4499EQ DAC and the preceding AK4497EQ. This process results in much-improved noise immunity in general, and increased low-frequency noise performance in particular.
While conventional DACs use a single chip to convert signals from digital to analog, new products split the conversion process between the AK4191EQ delta-sigma modulator and the AK4498EQ DAC. This innovative approach has resulted in an improvement in sound quality that is easily perceptible while listening to music.
