Additional Information about A01 Audio Motherboard
The A01 Motherboard is designed around the AKM flagship AK4497EQ DAC chipset. To make sure the premium DAC chipsets will operate in optimum condition, we have employed THREE extremely low-noise high-precision Femtosecond Crystal Oscillators (45.1584MHz, 49.152MHz, 100MHz). High precision low jitter digital transmission is the base of high quality digital playback. It is how we deliver a natural, non-digital and musical playback to subsequent audio circuit.
It is fully optimized for fully differential amplification, and the final headphone output stage employs 4 pieced of OPA1622 in parallel amplification configuration. This will increase the output current capability and lower the output impedance. In practical, these improvements will translate into better control, ability to sustain a heavier loading, and drive most portable headphones with ease and offers lots of headroom.
我諗$7k應該走唔甩
