The Pontus 15TH marks an unprecedented breakthrough in audio quality. By employing advanced audio enhancement technologies, it delivers sound that is more nuanced, profound, and intricately layered than ever before. This is not merely an upgrade — it represents a bold redefinition of traditional audio perception, offering enthusiasts an unparalleled listening experience.
This DAC features a true balanced R-2R ladder network array design, with each channel equipped with an independent high-speed CPLD. Digital signals are decoded through four sets of 0.005% precision R-2R networks, achieving exceptionally low distortion and minimal background noise. Every note resonates vividly, leaping to life with striking realism and depth.
The Pontus 15TH maintains the original sampling rate of the audio signal to the greatest possible extent. All digital inputs undergo FIFO buffering and are re-clocked by an on-board CPLD crystal oscillator, providing outstanding jitter suppression and reducing dependence on the source device’s clock. The result is a cleaner, more stable, and highly transparent sound.
Ingenious Power Design
The Pontus 15TH’s power architecture exemplifies meticulous engineering. Its innovative box-in-box design completely isolates the DAC motherboard from the linear power supply, preventing external interference from compromising audio quality. A metal alloy casing further enhances the purity and stability of the power supply, ensuring a silent and stable foundation for sonic excellence.
All digital inputs are FIFO buffered and re-clocked by on-board LPNO crystal oscillators, giving the DAC exceptional rejection of word-clock jitter. This design makes the Denafrips DAC far less reliant on source clock quality, allowing even standard computers or CD players to achieve high-end sound performance.
True Non-Oversampling R-2R DAC
As a non-oversampling (NOS) R-2R DAC, the Pontus 15TH preserves the audio signal’s native sampling rate without any additional digital processing. This ensures that every detail of the original recording is conveyed with complete authenticity and musical integrity.
Enhanced Power Supply & Conductors
Pure silver cables and conductors for optimal power transfer from the PSU to the DAC mainboard
Fine-tuned PSU components, enhancing AC/DC rectifiers and DC regulators for ultra-stable current delivery
Encapsulated Linear Power Supply
Clean power is the foundation of great sound. Beneath the DAC motherboard sits a dedicated linear power supply, fully enclosed in a 1.5mm-thick metal alloy housing. This box-within-box configuration eliminates the shortcomings of traditional dual-box solutions and reflects the precision and care invested in Denafrips’ premium DAC design.
Equipped with dual O-core transformers for digital and analogue sections, ultra-low ESR, long-endurance reservoir capacitors, and a multi-stage super-linear regulation system, the Pontus 15TH ensures an ultra-precise, low-ripple power supply that keeps the DAC performing at peak accuracy.
Refined High-End Performance
With its exceptional decoding precision, refined architecture, and innovative power system, the Pontus 15TH stands out as a shining star in the high-end audio landscape. It is more than an audio device — it is a pursuit of perfection and a tribute to the true art of music.
