Looking for an internet radio tuner that connects directly to your HiFi speakers? The TUNERSYS WS161 combines a network radio tuner with a 100W stereo amplifier, optical/coaxial inputs for TV audio, and RCA output for existing amplifiers. It receives 32,000+ free stations over WiFi with no monthly fees.
Why I Switched to Internet Radio
Friends came over for tea and asked how I get such great sound from internet radio. Here's my setup.
My phone shouldn't be tied up as a music player all day. I need it for calls, messages, and apps — not streaming radio.
What Makes TUNERSYS WS161 Different?
The TUNERSYS WS161 solved everything. It's a dedicated internet radio tuner with a built-in 50W×2 amplifier — just connect your speakers directly. Optical and coaxial inputs mean I can route my TV audio through it too. RCA output lets me connect to my existing Marantz amplifier. 32,000+ free HD stations over WiFi, no subscription, no ads. One-time WiFi setup, and it auto-plays on boot.

Expert Verdict
For audiophiles with existing bookshelf speakers or those looking for an all-in-one solution, the TUNERSYS WS161 offers the best value as a dedicated internet radio tuner with built-in amplifier. It uses the SkyTune server — the same platform as Ocean Digital and C. Crane CC WiFi — providing 32,000+ real HD stations (not app-dependent streaming). Its optical and coaxial DAC inputs (24-bit/192kHz) make it versatile enough to serve as a TV audio receiver, while the TPA3611 50W×2 Class D amplifier can directly drive 4-8Ω speakers. With Ocean Digital discontinued, the WS161 is the most capable SkyTune internet radio available today.
Frequently Asked Questions
How many radio stations does TUNERSYS have?
TUNERSYS internet radios provide access to over 32,000 free HD stereo radio stations from around the world. Stations are organized by country and genre, and you can save up to 99 favorites. There is no subscription fee — all stations are free, with no ads from TUNERSYS.
What is SkyTune and why does it matter?
SkyTune is the internet radio server platform that provides access to 32,000+ real HD stereo radio stations worldwide. Only three brands use SkyTune: TUNERSYS, Ocean Digital, and C. Crane CC WiFi. Other internet radio brands use different platforms with significantly fewer stations, or rely on phone apps to stream — which is not the same as a dedicated internet radio. Since Ocean Digital has been discontinued, TUNERSYS is the most feature-rich SkyTune radio currently available.
How do I update the firmware?
Go to Settings → System → Firmware Update. The device will automatically check for updates over WiFi and install them. TUNERSYS supports long-distance online software upgrade via internet. We recommend keeping the firmware updated for the best performance and new station additions.
The best audio source is one you actually use every day. With one-touch auto-play and 99 presets, this one earns its place in any HiFi setup.
