Comprehensive I/O for Versatile Integration

Dual GaN Switching Power Supply (100W Total)

CNC Precision-Milled Aluminum Chassis

True-Balanced High-Power Output

Silenos delivers up to 14W @ 32Ω continuous balanced power, not just peak values. This ensures it can effortlessly drive even the most demanding headphones, including high-impedance dynamics and planar magnetics, while maintaining excellent dynamic control and energy.

Complementary R2R Decoding Architecture

Featuring 192 precision resistors in a complementary R2R array, Silenos achieves exceptional circuit balance and error suppression. Supporting PCM up to 32bit / 768kHz, it produces an analog-like, natural sound with enhanced detail and accuracy.

Compact and Space-Efficient Design

Measuring only 18 × 16 × 4.5 cm, Silenos combines high output with a compact footprint. Ideal for desktop HiFi systems, studios, and personal listening spaces, it offers maximum power and versatility in a portable, space-saving form.

Comprehensive I/O Connectivity

Equipped with XLR, 4.4mm, 6.35mm, and 3.5mm headphone outputs, along with balanced preamp output, Type-C digital input, and XLR analog input, Silenos integrates seamlessly with headphones, active speakers, turntables, and CD players.

Dual GaN Power Supply Design

The dual GaN switching power modules provide up to 100W total output, offering cleaner, faster, and more stable performance than traditional silicon-based designs. This ensures low noise, high efficiency, and reliable operation even under heavy loads.

CNC Precision-Milled Aluminum Chassis

Crafted from a solid block of aluminum with anodized sandblasting, Silenos provides structural strength, EMI shielding, and efficient heat dissipation. This design ensures long-term stability, durability, and superior sonic purity.
