Denafrips PONTUS II DAC


PONTUS is DENAFRIPS premium DAC. To achieve the highest possible sound quality within the cost constraint, PONTUS adopted many of the the technologies found in the TERMINATOR DAC. Yes, that's right, PONTUS is designed around the similar architecture of the TERMINATOR DAC.

The chassis is made of massive aluminum plates, securely fastened with internal bracket and no visible sign of bolt from the front panel and top cover. The all-aluminum enclosure, double up as shielding and anti-resonance, the criteria for audiophile, yes?


The PONTUS is true balanced, dual mono R-2R network arrays DAC. Each channel is equipped with independent high-speed FPGA to control the decoding by means of 4 sets of 0.01% R-2R network. This design has very small linear error, high decoding speed, low digital noise, not only to ensure that the audio signal is low distortion, but also to ensure a very low background music noise; allow listener to enjoy the true music with dark background. 

All digital input are FIFO buffered and reclocked by the on board FEMTO clocks. The excellent rejection of word-clock jitter makes DENAFRIPS DAC less reliance to the source equipment clock quality. PONTUS can transform your consumer grade computer, CDPlayer to high-end sound quality.

PONTUS further enhanced the linear power supply design compared to the ARES II. The power supply is encapsulated in a thick metal alloy, equipped with dual o-core transformers, completely isolated super linear regulator, multistage power supply for digital and analogue sections, ensuring low noise, high availability power supply to the DAC.
