HiFiMuse HiFiMuse R20
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.

LHY Audio LHY Audio AS6
LHY Audio AS6 is an audiophile Gigabit Ethernet switch designed to provide a cleaner network foundation for high-resolution music streaming. Its isolated RJ45 output, SFP connectivity, internal OCXO clock and low-noise linear power architecture focus on reducing electrical noise before the signal reaches a streamer. Why it stands out Dedicated isolated audio port One galvanically isolated Gigabit RJ45 port is reserved for the streamer or network bridge most sensitive to incoming electrical noise. Fiber-ready network architecture An SFP port supports optical integration without requiring a separate consumer-grade switch. Precision internal clocking The built-in OCXO and Si5381 PLL provide a stable timing reference for the switching stage. External clock upgrade path A 10MHz 50-ohm BNC input allows the AS6 to join a system built around a compatible master clock. Best for High-resolution network streaming systems Streamers that benefit from an isolated Ethernet feed Systems combining copper Ethernet and an optical link Owners using a compatible 10MHz external master clock Compact HiFi systems needing multiple Gigabit network ports Not ideal for Users who need 2.5GbE or 10GbE networking Systems requiring several isolated RJ45 outputs Users expecting Wi-Fi routing or network management features Non-network audio systems with no Ethernet streamer EMiUZEK Buying Notes AS6 is an unmanaged network switch, not a router, music streamer or DAC. Use the isolated RJ45 port for the audio endpoint; the remaining RJ45 ports are standard Gigabit connections. The external clock input requires a compatible 10MHz, 50-ohm source and is optional for normal operation. Frequently asked questions Does the AS6 replace my router? No. Connect it downstream of your router or existing network infrastructure. Can it connect directly to a streamer? Yes. The isolated RJ45 port is intended for a network streamer or bridge. Does it support fiber? Yes. It includes one Gigabit SFP port; the correct transceiver and fiber type must match the other endpoint. Is an external clock required? No. AS6 has its own OCXO clock and operates normally without an external clock. What speed are the Ethernet ports? The network connections are Gigabit-class, not 2.5GbE or 10GbE. Does it play music by itself? No. It conditions and distributes network data; a streamer and audio system are still required.

LHY Audio LHY Audio AS8 Pro
LHY Audio AS8 Pro is a reference audiophile Ethernet switch that separates high-speed network traffic from an isolated audio zone. Dual linear power paths, SC-Cut OCXO clocking, optical isolation and 10MHz clock input/output make it a central network and timing hub for complex digital audio systems. Why it stands out Two purpose-built network zones A 10G/2.5G main zone handles servers and storage while an optically isolated Gigabit zone feeds sensitive audio endpoints. Reference clock integration 10MHz BNC input and output allow the switch to receive or distribute a compatible system clock. Extensive low-noise power design Dual toroidal transformers and multiple dedicated linear regulator stages isolate critical clock and network circuits. Flexible grounding control A dedicated grounding terminal and float/ground switch help match the switch to different system grounding strategies. Best for Reference streaming systems with NAS or Roon servers Systems requiring both 2.5GbE and isolated Gigabit audio links Installations using fiber between network zones Systems sharing a compatible 10MHz master clock Not ideal for Simple single-streamer systems with basic Gigabit needs Users needing router, Wi-Fi or managed-switch software Compact desktop setups with limited equipment space EMiUZEK Buying Notes AS8 Pro is an unmanaged switch and clock hub; it does not replace a router, streamer or DAC. The isolated audio zone is Gigabit-class; connect high-bandwidth servers and NAS devices to the main zone. Clock input and output must match the receiving equipment's 10MHz requirements. Frequently asked questions Which ports should feed my streamer? Use the isolated audio-zone RJ45 or SFP port. Can it connect to a NAS at 2.5GbE? Yes, the main zone provides four 2.5GbE RJ45 ports. Does it support 10Gb fiber? The main zone includes a 10Gbps SFP/SFP+ port; the isolated SFP zone is lower speed. Is an external clock required? No. Its internal SC-Cut OCXO operates independently. Can it send its clock to another device? Yes, it includes a 10MHz BNC output for compatible equipment. Is it a managed switch? No. It is plug-and-play rather than an enterprise managed switch.
