Description
The FiiO R9 brings together streaming, decoding, amplification, and preamp functions in a single desktop chassis built for serious listeners. At its heart sit two 8-channel ES9038PRO DAC chips wired in parallel for a fully differential output, paired with an 8-channel THX AAA 788+ amplifier module producing 7300mW into 32Ω to handle even the most demanding headphones. Five gain stages with variable gain and variable supply voltage let you match the output to sensitive IEMs or high-impedance planars, while OPA2211 op-amps manufactured via SiGe CMOS process maintain signal integrity through the entire audio chain. A 6-inch 2160×1080 portrait touchscreen runs Android so you can add your favourite streaming apps, and Roon Ready certification plus QCC5125 Bluetooth with LDAC keep wireless sources covered. The black and silver aluminium chassis features mirror-polished silver side panels alongside matte black surfaces, with RGB illumination that changes colour with the active codec. Headfonia reviewers note the solid all-aluminium construction and generous accessory bundle, while Headfonics points to the extensive I/O selection and strong output headroom. The DC/AC dual power supply architecture also accepts external 15V/3A linear power supplies for further sonic refinement.
