Pontus 15th has achieved a significant breakthrough in sound quality, adopting advanced audio enhancement technology to make the sound more delicate, profound, and layered. This is not only an upgrade, but also a challenge to traditional audio concepts, bringing an unparalleled auditory experience.

This DAC adopts a balanced R-2R design, with independent channels equipped with high-speed CPLDs. It uses four sets of 0.005% R-2R network decoding to ensure low distortion and background noise, allowing each note to resonate vividly.

The power design of Pontus 15th is ingenious, adopting a box in box design to perfectly isolate the DAC motherboard from the linear power supply, effectively preventing external interference. Meanwhile, the metal alloy casing enhances the purity and stability of the power supply.

1. The application of high-quality capacitors in Pontus 15th, DENAFRIPS has chosen capacitors with superior electrical performance and greater stability. Compared to the 12th version capacitor, the 15th version capacitor performs well in both low-frequency control and high-frequency clarity.

2. The power supply line has been upgraded to silver wire in the power supply section of Pontus 15th, using silver wire as the power line. Silver wire has better conductivity than traditional copper wire, making the sound performance more obvious, the sound quality more transparent and delicate, and the low-frequency depth and high-frequency details have been improved.

1. LPNO crystal oscillator (45.1548MHz and 49.152MHz) LPNO crystal oscillator has low power consumption, high frequency stability, and good negative output characteristics, which can maintain consistent performance under temperature changes and load conditions, and enhance compatibility with various digital circuits.

2. Core chip upgrade: Pontus 15th's core chip upgrade has stronger computing power and higher data processing efficiency, especially performing well in processing complex high sampling rate audio.

1. Algorithm optimization of R2R architecture Pontus 15th still adopts the classic R2R architecture, but optimizes the algorithm, improves dynamic range and signal processing accuracy, making the sound quality more delicate and natural.

2. Optimization of R2R architecture power supply system We have comprehensively optimized the R2R power supply system of Pontus 15th, reducing power supply noise and electromagnetic interference through independent power supply modules and multi-stage filter design.

1. The unique power supply system of Pontus 15 adopts a dual power supply system, with a transformer supplying power to both the digital signal processing module and the analog signal processing module. This design effectively separates various circuit modules and avoids mutual interference.

2. Transformer upgrade: Single crystal copper enameled wire vs oxygen free copper enameled wire Pontus 15th uses a single crystal copper enameled wire transformer, while Pontus 12th uses oxygen free copper enameled wire. Single crystal copper has better conductivity, providing more stable current transmission and lower signal loss
