This product is a dual AK4499EQ decoder, not a typical single core AK4499EQ decoder. The LPF output is the cutting-edge operational amplifier MUSES03. The AK4499 decoder currently being shipped has been upgraded to a high-definition OLED display!
After the iconic AK4497EQ from Asahi Kasei AKM Electronics Co., Ltd., a new VELVETSOUNDVERITADAC has been developed
AK4499EQ。 This product, as the first AKM to adopt current output mode, has achieved the world's highest level of low THD+N He
High S/N. Featuring THD+N of -124dB (AK4497EQ of -116dB) and a single channel signal-to-noise ratio of 140dB
(AK4497EQ is 131dB) There is a significant improvement compared to the previous flagship product AK4497EQ.
This is a decoder at the HI END level, which includes layers, details, positioning, air quality, vocals, density, and more
Very ideal, you can be picky.

At present, the LPF output has been upgraded to MUSE series' most high-end operational amplifier MUSES03 super high-end operational amplifier, with very realistic and natural sound, and sweet human voice. The conversion rate is as high as 35V per microsecond, far exceeding MUSE02 and MUSE01, not to mention the cheap LME49860. The IV part is OPA1612, and the conversion distortion is as low as 0.000015%!
