Decode and output to desktop speakers and other wired audio devices, bringing a wireless world to them.                                                                                    Massive Driving Power                        Exceeding the power of many desktop headphone amplifiers, the 1523mW output easily drives all types of full-size headphones.                                                                                    Cyberpunk Industrial Design                        With instantly recognizable body lines, front-facing color LEDs, and a transparent OLED display, the FD5 captivates visitors with its cyberpunk retro-futurism aesthetic.                                                                                    Discrete Power Supply                        An isolated power supply shields the analog conversion/amplification circuitry from EMI from the power supply. The fully isolated power supply includes filtering and regeneration to isolate the FD5 from any electrical grid noise. It uses 10 ELNA SILMIC II capacitors in the power supply section and an isolated DC power supply with an analog module powered by a high-resolution OPA1652 opamp for active noise isolation and voltage regulation.                                                                                    4x AK4493 DAC Array                        Utilizing four AKM AK4493 DAC chips, the FD5 uses current mode amplification for powerful output and an exceptional signal-to-noise ratio. The system includes class A/AB amplification switch, LPF comprising 6 OPA1612, high-quality headphone amplification with 2 ADA4625-2, and a fully discrete headphone amplifier formed of 32 hand-matched transistors.
