 Integrates high-end transmission/decoding/headphone amplifier/jukebox/preamplifier functions in one device Equipped with an unimaginable number of inputs and outputs and ten operating modes With open Android operating system + 6-inch FHD screen + portrait format With classic bicolour metal design like luxury cars Thoroughly upgraded inside and out to take your desktop hi-fi experience to the next level 8-channel DAC ES9038PRO*2 Since the ES9038PRO has already been used in the M17, Q7, K9 Pro SS and M15S, FiiO now has a lot of experience with the chip and can thus raise the audio quality to a new level. The FiiO R9 has two ES9038PRO DACs, one for the left and one for the right channel. Each DAC chip contains 8 independent D/A converters, and these 8 channels are connected in parallel to provide a fully differentiated output. The result is a precise, clear and full sound. 

DNR: 132dB 

THD+N: -122dB 

 

 

Inside the FiiO R9 is an 8-channel THX AAA 788+ headphone amplifier design. These headphone amplifiers, powered by a high-voltage power supply, are paralleled in 2×2 groups to create a fully balanced four-way design that significantly improves transient performance. The comb-shaped heat sinks and optimised circuit layout efficiently dissipate heat and ensure that the R9 can deliver continuous and stable high output power. The result is that the R9 is capable of delivering 7300mW per channel at 32Ω, 102% more than the R7. 

 

 

 The FiiO R9 delivers impressive audio performance thanks to its five-stage audio architecture with carefully designed IV, LPF, gain, preamplification and current expansion stages. A key component of the audio circuitry is the OPA2211 operational amplifiers, which are manufactured in the Silicon Germanium (SiGe) CMOS fabrication process that ensures the chip's outstanding performance. The variable gain and variable supply voltage result in 5 gain levels, allowing you to precisely set the desired volume. Whether you're using IEMs or hard to drive headphones, you'll have a great listening experience. 

 

 

The FiiO R9's internal power supply, digital parts, DAC and headphone amplifier are all located on separate circuit boards. In addition, there are metal shields to completely isolate the DAC and THX headphone amplifier sections. These four main components of the audio circuitry are housed on independent boards to avoid crosstalk, ensuring that the processed audio signals and their output are accurate, clean and maintain their dynamics. 

 

 

FiiO R9 features a new, low-noise, high-efficiency and long-life industrial-grade 40W power supply that supports an extremely wide input voltage range (85~305VAC) and can operate in a wide temperature range (-40?~85?) and is designed to last 500,000 hours. The FiiO R9 can also be powered by an external DC power supply*, allowing you to pair the R9 with a powerful linear power supply that provides its own sound. When the R9 is connected to an external power supply, you can also activate the "Ground Lift" function to reduce crosstalk and achieve a cleaner sound. 

*External DC power supplies with 15V-3A are supported. 

 

The FiiO R9 has separate power supplies for the digital and analogue parts of the audio circuit, preventing crosstalk between the digital/analogue parts and providing better isolation and shielding between the two parts. 

 

The analogue part of the audio circuit has a finely divided, multi-stage power supply, including digital-to-analogue conversion, LPF, preamp processing, gain drive and other power supply stages. Each power supply stage uses many precision LDOs to stabilise the secondary voltage, ensuring a clean and stable power supply. 

 

 

For an improved sound image and better overall sound quality 12 low-loss metallised film capacitors for a wide operating temperature range + 70 high-precision, low-noise film resistors 

Low temperature drift and low noise, regardless of temperature fluctuations, ensure stable, high-quality sound, whether in hot or cold environments 

5 sets of silver-plated, oxygen-free copper cables for connection 

Silver-plated, oxygen-free copper wires are used to connect the various circuit boards to ensure low-loss, high-quality signal transmission 

 

 

 The FiiO R9 has a large 6-inch screen with 2160*1080 pixels in portrait format, which in combination with the open Android operating system offers a thoroughly intuitive experience. The open Android operating system not only allows the user to freely install and use third-party music streaming and other apps, but is also so sophisticated that the user does not have to worry about app compatibility issues.
