M400 is a brand-new design series. From the exterior shell to the circuit architecture, it uses AKM’s new DAC chip-AK4499, and focuses on the power supply. It is equipped with 8 Panasonic 330UF E-type tantalum capacitors and 4 OPA1612 as IV conversion. With full firepower, each 4499 has a 4-channel output, each channel has an IV conversion, non-castration design (some products only use 2 IVs for each 4499), and the final combination can achieve very high sound quality Level, volume control adopts Texas Instruments PGA2311UA, 2 pieces, combined into 4-channel synchronous adjustment, no compression dynamics, no partial sound, long life, secondary screen display volume, gain, DAC filter, etc., balanced output The 4.4 output port is adopted, and the grounding function is retained. SF Express is available from stock. The latest batch is changed to a tempered glass cover, which is more beautiful
