Why I Switched to Internet Radio
My expensive amplifier and bookshelf speakers were collecting dust because I couldn't find a good digital source.

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
Can the WS161 play FLAC and WAV files from my NAS?
Yes. The WS161 supports UPnP/DLNA streaming over your local WiFi network. It can play FLAC, WAV, MP3, AAC, and WMA files stored on your NAS or PC. It supports up to 24-bit/96kHz gapless playback.
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.
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.
In the age of subscriptions and smart speakers, a dedicated internet radio tuner feels refreshingly simple — and the sound quality speaks for itself.
