HiFiMuse R20 is a compact Wi-Fi, Ethernet and Bluetooth 5.3 audio streamer for adding network playback to an existing amplifier, DAC or powered-speaker system. It supports app-controlled streaming, local lossless files, HDMI ARC, USB storage, analog audio and optical output, with an onboard Actions BP1048 audio processor/DAC. Why it stands out Flexible system integration HDMI ARC, AUX input/output, optical output, subwoofer output, USB Host and RJ45 Ethernet cover TV, stereo, DAC and powered-speaker systems. Wi-Fi, Ethernet and Bluetooth 5.3 Use network streaming for supported services and local files, wired Ethernet for stability, or Bluetooth 5.3 for quick playback. Practical app choices Android users configure R20 with AudioCast; Apple users can use WiiM Home or AudioCast R20. Clear digital-output behavior The optical output uses a fixed 48 kHz internal processing path, so buyers know it is not a bit-perfect passthrough output. Best for Adding streaming to an existing amplifier or powered speakers TV audio systems using HDMI ARC Local FLAC, WAV, ALAC or other supported file playback Systems requiring analog, optical, subwoofer or Ethernet connectivity Multi-room playback through compatible app-controlled devices Not ideal for Listeners requiring bit-perfect optical passthrough at the source sample rate Buyers expecting Spotify Lossless support Systems needing built-in speaker amplification Users requiring every button on the universal remote to control DSP functions Product Details and Connection Views EMiUZEK Buying Notes Spotify Connect is supported, but Spotify Lossless is not confirmed; Spotify currently reports up to Very High quality at 320 kbps. The optical output is processed internally at a fixed 48 kHz and can resample 44.1 kHz sources. The universal remote supports basic controls, but DSP, bass and treble buttons may have no effect depending on the operating mode. Frequently asked questions Does R20 support Spotify Lossless? Spotify Connect is supported, but Spotify Lossless is not currently confirmed. If Spotify shows Very High as the maximum setting, the stream is the standard 320 kbps compressed Spotify stream. What does “lossless wireless streaming” mean for R20? It refers to supported lossless file playback such as FLAC, WAV and ALAC from compatible local storage or network sources. It does not mean every streaming service delivers lossless audio. Is the optical output bit-perfect? No. The optical output follows a fixed 48 kHz internal processing path, so a 44.1 kHz source can be resampled before output. Why does the optical output use 48 kHz? R20 routes audio through internal processing used for volume control, input switching, EQ and multi-room synchronization. The optical output therefore does not always preserve the source sample rate. Which app should I use for setup? Android users should use AudioCast. Apple users can use WiiM Home or AudioCast R20. Which remote-control buttons work? Power, volume, mute, playback, input selection and preset buttons provide the basic controls. DSP, bass, treble and other platform-wide buttons may not be implemented on R20, and they should not be expected to alter the optical digital signal. What is included in the standard package? The standard package includes the R20, power adapter, USB power cable, remote control, antenna pair, optical cable, 2-to-1 RCA cable and user manual. Can I use R20 with a vintage amplifier or external DAC? Yes. Use the analog output with an AUX or line input, or use optical output with an external DAC while accounting for the fixed 48 kHz processing path.
