FiiO K9 Pro ESS Desktop DAC and Amplifier, Precise Design, Fully Differential, Fully Balanced Design

Electricity is the mother of sound, so special attention was paid to optimize the FiiOK9 Pro ESS Desktop DAC and Amplifier’s power supply to ensure excellent sound. The FiiO K9 Pro ESS’s linear power supply, with its low-frequency transformer and 4 massive 4700uF capacitors, makes sure that the rest of the system gets abundant clean power.

THX AAA 788+ Chips

The THX AAA 788+ chips used in the FiiOK9 Pro ESS Desktop DAC and Amplifier provide exemplary details and dynamics no matter if you are using low or high-impedance headphones. The K9 Pro ESS can produce an undistorted 1100mW as tested in FiiO Labs under balanced out under a 300 ohms load, and an undistorted 2100mW under a 32 ohms load, 50 percent higher than the original THX AAA 788 amplifier chips.

Precise Design

Fully differential signals go through the DAC, volume adjustment, and amp for a truly balanced design. Such a design ensures minimal interference between different components in order to fully maintain all details and large dynamic swings in music for unmatched sound quality.

Fully Differential, Fully Balanced Design

The PCB of the K9 Pro ESS uses a partitioned layout, wherein not only the power supply and signals are separated, but the analog signal loop is also put in an independent section, guaranteeing the integrity of the audio signal being processed. Every audio signal goes through a mammoth 6-stage circuit to reproduce music as faithfully and as detailed as possible. The six-stage audio circuit reveals every last detail.

Indicator Lights

The RGB indicator lights surrounding the volume knob can light up differently depending on the currently playing sampling rate.
