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
After comparing 5 different network players, I finally found one that matched my HiFi standards.
CD discs are becoming obsolete. They scratch easily, take up space, and new releases are increasingly digital-only.
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 does the WS161 compare to a dedicated network streamer?
Dedicated network streamers (Bluesound, Cambridge Audio) cost $500-1,500+ and require app control. The WS161 at $280-420 includes a built-in amplifier, optical/coaxial DAC, 32,000+ free stations via SkyTune, UPnP streaming, and works standalone with no app required. For most audiophiles, it offers better value.
Can the WS161's 50W amplifier drive floor-standing speakers?
The built-in 50W×2 TPA3611 amplifier is designed for 4-8Ω bookshelf speakers and high-sensitivity floor-standers. For large, low-sensitivity floor-standing speakers, we recommend using the RCA output to connect to a dedicated power amplifier for better dynamic range.
What is the benefit of upgrading to a linear power supply?
The WS161 supports DC 9-24V input. Upgrading from the stock switching power supply to a linear power supply (recommended 16-18V, 50-80W) reduces background noise and improves audio clarity. Popular options include Topping, iFi, and Chinese boutique linear PSUs with 5.5/2.1mm DC connectors.
It's a luxury to have a dedicated audio source that doesn't tie up your phone. TUNERSYS gives you that independence.
