Hybrid R2R and 1bit DAC for Ultimate Sound Quality

• The D17 combines two advanced DAC architectures
• R2R ladder DAC for natural and analog like sound
• 1bit PWM DAC for high resolution detail and accuracy

This hybrid system delivers a perfect balance of warmth, detail, and dynamic performance, offering a truly lifelike audio experience.

Fully Balanced Four Channel R2R Architecture

The D17 features a fully balanced R2R DAC with 284 high precision resistors. This design ensures excellent linearity, low distortion, and superior signal accuracy.

The result is a smooth, rich, and highly musical sound signature with exceptional tonal balance.

1bit PWM DAC for Enhanced Resolution

The 1bit architecture uses 64 PWM DAC units working in perfect synchronization. Controlled by FPGA Master 3.0, it ensures precise timing and improved signal density.

This enhances micro detail, clarity, and overall sound realism.

Dual Nutube Amplification for Warm and Dynamic Sound

The D17 incorporates two Korg Nutube tubes, delivering a natural tube sound with warmth, depth, and smoothness. Combined with a high performance buffer stage, it provides powerful and controlled output.

With over 1200mW per channel at 32 ohms, it can drive demanding headphones with ease.

FPGA Master 3.0 for Ultra Precise Processing

The advanced FPGA system controls timing, signal alignment, and clock regeneration with nanosecond level accuracy. This minimizes jitter and ensures highly accurate sound reproduction.

Dual Battery Design for Pure Power

The D17 uses separate batteries for the DAC and amplifier sections. This eliminates interference and provides stable power delivery, resulting in cleaner sound and improved performance under load.

Precision Volume Control System

The combination of a 24 step analogue attenuator and digital volume control allows precise adjustment with perfect channel balance. This ensures consistent performance at all listening levels.

Advanced Mechanical Design for Reduced Interference

A multi layer isolation system reduces vibration and microphonic effects, especially important for tube based designs. This ensures stable and consistent sound performance.
