FangSound Silenos - R2R DAC/AMP Desktop All-in-One (14W)




FangSound Silenos - R2R DAC/AMP Desktop All-in-One (14W)
Delivery time approx. 1–2 weeks
SILENOS
The FangSound Silenos combines a discrete, complementary R2R resistor network (up to 32 bit / 768 kHz) with an outstanding continuous output power of 14 W into 32 Ω, allowing it to drive even the most demanding headphones effortlessly and musically.
The device is rounded out by a CNC-machined full-aluminum housing, a clean 100 W dual-GaN power supply, and comprehensive connectivity for flexible use as a headphone amplifier and dedicated preamplifier.

Core Features
-
True balanced high-power output: 14 W @ 32 Ω continuous-load drive power
The Silenos delivers up to 14 W of continuous, fully balanced output power into a 32 Ω load. Unlike conventional products that only specify peak values (“Peak”), the Silenos offers genuine, continuously available high performance. It can drive high-impedance and low-sensitivity headphones stably—including large planar magnetic headphones and flagship dynamic models. Thanks to outstanding dynamic-range control, it reproduces the finest details and the full energy of the original recording without alteration.
-
Complementary R2R DAC architecture (supports up to 32 bit / 768 kHz)
The Silenos uses a discrete, complementary R2R resistor network for highly precise digital-to-analog conversion. The circuit was optimized for excellent symmetry and error suppression, delivering a natural, analog-like listening experience. PCM formats up to 32 bit / 768 kHz are supported; internal oversampling is also integrated for enhanced signal fidelity and resolution.
-
CNC-precision-machined full-aluminum housing with shielding and thermal stability
The housing is CNC-machined from a solid block of aluminum and anodized/sandblasted, ensuring high structural stability and electromagnetic shielding. This effectively suppresses digital noise and mechanical resonances while providing excellent heat dissipation for stable continuous operation.
-
Comprehensive connectivity for a wide range of system requirements
The Silenos offers a wide range of inputs and outputs for flexible integration into various headphone and Hi-Fi systems:
-
Headphone outputs: 4-pin XLR balanced, 4.4 mm balanced, 6.35 mm jack (unbalanced), 3.5 mm jack (unbalanced)
-
Analog input: XLR (Note: When using this input, please disconnect the Type-C plug on the rear panel)
-
Digital input: USB Type-C
-
Preamp output: 4.4 mm balanced (connectable via adapter cable to active XLR or RCA speakers or power amplifiers)
Thanks to this design, the Silenos is equally suitable as a high-performance headphone amplifier and as a full-fledged standalone preamplifier in larger audio systems.

Amplification, preamp & power supply
-
Unleash the full potential of your earphones and headphones:
-
Low Gain: Ideal for sensitive in-ear monitors (IEMs).
-
High Gain: Designed for the most demanding planar-magnetic and dynamic headphones.
-
-
Powerful preamplifier:
In audiophile circles, the maxim is: “The preamp determines the sound; the power amp delivers the power.” This underscores the central role of the preamp. The Silenos preamp far exceeds expectations for its price class, providing the system with improved detail resolution, a wider dynamic range, and a more immersive musical experience.
-
Dual GaN power supply with 100 W total output power:
Equipped with two GaN switching power supply modules (gallium nitride), the system delivers a combined output of up to 100 W. Compared with conventional silicon-based power supplies, GaN offers higher efficiency, lower electromagnetic interference (EMI), and faster regulation response times—for clean, stable, and noise-free power delivery even under full load.
