The FiiO SR11 is a compact digital streaming transport that adds network playback to an existing DAC, integrated amplifier or active speaker system with a compatible digital input. It receives music over Ethernet, Wi-Fi, AirPlay, Roon, Bluetooth or local USB storage, then sends a digital signal through USB, optical or coaxial output.

The SR11 does not contain an analog DAC stage, headphone amplifier or speaker amplifier. Its purpose is to preserve your existing audio system while adding convenient streaming control and high-resolution digital transport capability.

Why it stands out

Roon Ready and AirPlay in one compact transport

Use dedicated Roon Ready or AirPlay modes, or select MIX mode so the SR11 can remain available to either ecosystem without repeatedly changing the operating mode.

USB, optical and coaxial digital outputs

Connect modern USB DACs through USB-A or USB-C, or use optical and coaxial S/PDIF with traditional DACs, amplifiers and active speakers.

Gigabit Ethernet and dual-band Wi-Fi

A 1000Mbps Ethernet port supports stable wired streaming, while 2.4GHz and 5GHz Wi-Fi provide flexible placement when a network cable is impractical.

Useful front-panel control and included remote

The LCD shows operating mode, output, network status, volume and sample-rate information, while the supplied infrared remote controls key functions from the listening position.

Best for

• Adding Roon Ready or AirPlay streaming to an existing external DAC
• Hi-Fi systems that already provide optical, coaxial or USB digital input
• Listeners who prefer a dedicated network transport instead of using a computer
• Compact desktop or two-channel systems that benefit from Ethernet and Wi-Fi

Not ideal for

• Users who need analog RCA or XLR outputs
• Anyone expecting to connect headphones or passive speakers directly
• Buyers who need Spotify Connect, TIDAL Connect or Chromecast as a guaranteed native endpoint
• AirPlay users expecting native high-resolution output above 44.1kHz/16-bit

EMiUZEK Buying Notes

• The SR11 is a digital transport only. Your system must include a separate DAC or a component with a compatible USB, optical or coaxial digital input.
• Update the unit to current firmware before setup. Firmware V630 adds Bluetooth Receive, local USB playback, DLNA, FiiO Link and OTA functions; some features are unavailable on older firmware.
• USB and S/PDIF output cannot operate at the same time. In S/PDIF mode, optical and coaxial output operate simultaneously; the USB-A and USB-C audio outputs also cannot feed two DACs simultaneously.
• AirPlay converts incoming audio to 44.1kHz/16-bit. Choose Roon over USB when the connected DAC and source library require the SR11's highest supported resolution.

Frequently asked questions

Does the FiiO SR11 contain a DAC?

No. The SR11 outputs digital audio only. Connect it to an external DAC, an amplifier with a digital input or active speakers with compatible digital decoding.

Can I connect headphones directly?

No. It has no headphone output or headphone amplifier. A separate DAC/headphone amplifier is required.

Can it connect directly to passive speakers?

No. Passive speakers require an amplifier. The SR11 should feed a DAC or an amplifier that accepts one of its digital outputs.

Does it support Roon Ready?

Yes. In Roon mode, the SR11 appears as a Roon Ready endpoint on the same network. Roon over USB supports up to PCM 768kHz/32-bit and DSD256 DoP when the connected DAC supports those formats.

What is MIX mode?

MIX mode keeps both Roon Ready and AirPlay reception available. They cannot play simultaneously; only one sending device can use the SR11 at a time.

Does AirPlay provide high-resolution output?

No. FiiO specifies that PCM, DSD and MQA sources received through AirPlay are converted to 44.1kHz/16-bit before output.

Does the SR11 support AirPlay 2?

FiiO documents the feature as AirPlay rather than guaranteeing AirPlay 2. Treat it as an AirPlay receiver and do not purchase it specifically for AirPlay 2 multiroom functionality.

Does it support Spotify Connect, TIDAL Connect or Chromecast?

These are not listed by FiiO as native SR11 endpoint modes. They may be accessible through another supported ecosystem or casting method, but should not be assumed to work as dedicated native Connect endpoints.

Can it receive Bluetooth audio?

Yes, after updating to V630 firmware or later. Bluetooth Receive supports SBC, AAC and LDAC, then sends the received audio to the selected digital output.

Can it play music from a USB flash drive?

Yes, with V630 firmware or later and the latest FiiO Control app. Both USB-A and USB-C data ports support storage, but two drives cannot be used at the same time.

Which local file formats are supported?

FiiO lists AAC, AIF, AIFF, APE, M4A, DSF, DFF, FLAC, MP3, WAV and WMA. OGG and CUE splitting are not supported for local playback.

Can USB and coaxial output play at the same time?

No. Select either USB output or S/PDIF output. When S/PDIF is selected, optical and coaxial outputs operate simultaneously.

Can USB-A and USB-C feed two DACs simultaneously?

No. Both ports can connect to an external USB DAC, but only one USB audio output is active; by default, the first connected compatible device is used.

Which output provides the highest resolution?

USB supports the highest specified Roon rate, up to PCM 768kHz/32-bit and DSD256 DoP. Optical and coaxial support up to PCM 192kHz/24-bit and DSD64.

Should I use Ethernet or Wi-Fi?

Both are supported. Gigabit Ethernet is preferable when maximum network stability is important; dual-band Wi-Fi is convenient when cabling is difficult.

Does it have a battery?

No. The SR11 requires continuous 5V/2A power through its dedicated USB-C power input.

Can I use a different power supply?

Use a stable 5V/2A USB power supply that meets FiiO's requirement. Higher-voltage fast-charging output is unnecessary because the SR11 is specified for 5V input.

Why is there no sound after connection?

Confirm that the source and SR11 are on the same network, select the correct receiving mode, then match the SR11 output setting to the connected DAC. USB and S/PDIF modes are selected separately.

How is firmware updated?

Firmware can be installed from a USB flash drive through the USB-A or USB-C data port. Later firmware also supports OTA updating where available.
