Frequently Asked Questions
What's the difference between WS163 and WS161 for desktop use?
The WS163 (0.8kg, $228) is a pure tuner — no amplifier, no optical/coaxial input, just 3.5mm output. Perfect if you already have powered speakers or an amplifier on your desk. The WS161 (2.5kg, $280-420) adds a 50W×2 amplifier, optical/coaxial DAC, and RCA output — choose it if you want to drive passive speakers directly.
Why choose a pure tuner like the WS163 over an all-in-one?
Audiophiles who already own quality amplifiers and speakers don't need another amplifier in their signal chain. The WS163 provides a clean, focused audio source at a lower price point ($228 vs $280-420 for WS161), letting your existing equipment do what it does best.
Can I use the WS163 with powered desktop speakers?
Yes. Connect the WS163's 3.5mm output directly to your powered speakers' 3.5mm or RCA input. The WS163's compact 0.8kg form factor makes it ideal for desk setups where space is limited.
It's a luxury to have a dedicated audio source that doesn't tie up your phone. TUNERSYS gives you that independence.
