FiiO R9 Review: Flagship DAC Meets Headphone Power

Who Should Buy It

Key Specifications

Overview

The FiiO R9 is described in the listing as a flagship desktop audio playback and decoding headphone amplifier all in one machine, built to connect headphones, active speakers and other devices rather than function as a conventional multichannel home theater receiver.

Its core pitch combines a high resolution DAC section, a powerful headphone amplifier, an HDMI connection for video, and an Android based touchscreen interface for streaming, all in one upper mid-range priced box rather than several separate components.

Because the listing frames this primarily as a headphone amplifier, preamplifier and decoder, several specs that matter for a traditional speaker driving amplifier, including watt per channel into typical loudspeaker impedances, are simply not part of the given feature set. That framing matters for how a buyer should read the rest of this review, since comparisons to a conventional stereo receiver or integrated amplifier only go so far before the two categories diverge in what they are actually built to do.

Power and Sound Quality

Per the listing, the R9 pairs two ES9038PRO DAC chips with eight THX AAA 788 plus amplifier modules, a combination aimed squarely at headphone performance rather than speaker level output. That is a notably dense amount of DAC and amplification hardware for a desktop unit.

Per the listing, output power remains undistorted at 7300 milliwatts per channel into 32 ohm headphones, a genuinely high figure for headphone amplification and one that should comfortably drive demanding over ear headphones without running out of headroom.

What the listing does not provide is a speaker level wattage figure, which matters if a buyer intends to use the R9's preamp output to drive a separate power amplifier and speakers rather than headphones directly.

Connectivity and Inputs

The R9 is positioned as a professional digital turntable, preamplifier and decoder in the listing's own words, meaning it can sit at the front of a system selecting and converting digital sources rather than simply being a headphone amp bolted onto a DAC.

HDMI decoding, HDMI video output and HDMI ARC are all named, letting the unit connect to televisions, gaming consoles, Blu-ray players and monitors for combined audio and video output, which is unusual flexibility for a device built primarily around headphone listening.

The listing does not specify how many analog RCA or XLR outputs are present, nor does it list digital coaxial or optical input counts, so buyers planning a specific cabling layout around existing gear should confirm those details separately. That gap is worth weighing against the unit's stated role as a preamplifier, since a preamp output feeding a separate power amplifier typically depends on exactly this kind of connector detail to plan a system around it with confidence.

Formats, Processing and Room Correction

Room correction and multichannel processing are not relevant here, since the R9 is a headphone and preamp focused device rather than a speaker driving surround receiver, so this section focuses on decoding and format handling instead.

The listing describes high definition audio playback and decoding as a core function, built around the dual ES9038PRO DAC chips, though it does not itemize specific supported file formats, sample rates or bit depths beyond that general description.

Roon Ready certification is a meaningful inclusion for buyers already using Roon as their playback software, since it allows the R9 to act as a certified network endpoint rather than relying on a workaround connection method. Buyers chasing a specific hi-res resolution ceiling or a named lossless codec list will not find that level of detail in the given feature set, even though the general decoding capability is described with confidence.

• Dual ES9038PRO DAC chips for high resolution decoding
• Eight THX AAA 788 plus headphone amplifier modules
• HDMI decoding and HDMI ARC
• DLNA, AirPlay and Roon Ready network playback
• Android operating system with third party streaming app support

Features, Streaming and Apps

The R9 runs Android in an open mode, controlled through a 6 inch full HD touchscreen, which lets a user install and operate third party streaming apps directly on the device rather than only through a connected phone or computer.

Named services in the listing include Apple Music, TIDAL and Spotify, alongside DLNA and AirPlay support, giving several concrete paths to streamed audio without requiring every source to be a local file.

Control is not limited to the touchscreen either, since the listing also describes a remote control app and the included RM3 physical remote, which together support both desktop and long distance operation depending on where the unit is placed.

Build, Design and Controls

The chassis uses a dual tone metallic design with an imported protective film described as 4H hardness, intended to resist fingerprints and scratches on the surface, a detail more commonly associated with phone screens than audio components.

A high density metal body is credited in the listing with reducing sound degradation caused by deformation and vibration, framing the chassis build as a functional part of audio performance rather than purely cosmetic.

No dimensions or weight are published, so buyers cannot confirm desk footprint or how substantial the unit feels before ordering, which is worth checking separately given the amount of internal hardware described. Given the touchscreen, dual DAC chips and eight amplifier modules packed inside, a reasonable expectation is that the chassis carries more heft than a typical compact headphone amp, though the given feature list stops short of confirming that with a number.

Setup and Daily Use

Setting up the R9 for headphone listening is straightforward, connecting headphones directly to the unit and using the touchscreen or a connected app to select a source, whether that is a streaming service or a locally stored file.

For video use, HDMI decoding and ARC support let the R9 sit between a television and other devices, handling audio decoding duties while passing video through, which suits a desktop or near field setup more than a dedicated living room rack.

Day to day, switching between headphone listening, network streaming through DLNA or AirPlay, and HDMI connected video sources should be manageable through the touchscreen interface, supplemented by the included RM3 remote for operation from a short distance away. Buyers moving between apps on the touchscreen itself should find the experience closer to a tablet than a traditional amplifier front panel, which is either a welcome change or an adjustment period depending on how used a listener is to physical knobs and buttons.

Who Should Buy It

The R9 fits headphone enthusiasts who want flagship grade DAC chips and high stated output power in a single desktop unit, rather than assembling a separate DAC, headphone amp and streamer from different brands.

It also suits buyers who want HDMI connectivity bundled into that same headphone centric device, letting it double as a small desktop hub for a television or game console alongside headphone listening.

Roon users and buyers who want direct access to streaming apps from a touchscreen, without picking up a phone each time, are also a strong match given the Android interface and Roon Ready certification named in the listing. Buyers who split their time between headphones and a nearby television benefit most from the dual role here, since switching from one to the other does not require unplugging and reconnecting separate boxes.

Alternatives Worth Considering

Buyers who specifically want a conventional stereo integrated amplifier with a published speaker wattage figure, rather than a headphone centric device, would be better served by a traditional stereo receiver or integrated amplifier instead of the R9.

For a simpler and much lower cost streaming amplifier aimed at driving a pair of passive speakers directly, something like a WiiM Amp occupies a very different niche, trading away the R9's headphone amplifier depth and HDMI features for straightforward speaker output.

Those who want a dedicated phono stage as part of their setup will need to add a separate phono preamp upstream of the R9, since no phono input is described for this unit. Buyers comparing the R9 against a standard AV receiver should keep in mind that channel count, surround formats and speaker wattage simply are not part of what this device is built to do, so a side by side comparison on those terms would not be fair to either product.

Verdict

The FiiO R9 is a strong pick specifically for headphone focused listening, backed by a genuinely high stated output figure and a serious amount of DAC and amplification hardware packed into one chassis.

Buyers who need confirmed speaker wattage, a phono stage, or published physical dimensions should look elsewhere, since those gaps are real and not simply omissions in this review, but the headphone and streaming core of the R9 is well documented and capable.
