Denafrips Marks 15 Years of Audio Excellence with the Ares 15th R-2R DAC

Founded in 2012 and headquartered in Guangzhou, DENAFRIPS has earned worldwide acclaim for delivering high-end audio without the luxury price tag. Best known for its R-2R DACs, along with DDCs, preamps, power amps, and headphone amplifiers, the brand has built a loyal following among discerning audiophiles.

To celebrate 15 years of innovation, DENAFRIPS introduces the Ares 15th—a high-performance, fully balanced NOS R-2R DAC. At its core, the digital-to-analog conversion stage employs 480 precision resistors managed by an Altera FPGA, ensuring exceptional accuracy and musicality. The robust power supply features a 60VA O-core transformer wound with UP-OCC copper, eight LDO regulators, and an array of high-quality capacitors, all working together to deliver a stable and ultra-clean signal path.

The result is audio reproduction that’s precise, transparent, and richly detailed—a fitting tribute to DENAFRIPS’ 15-year pursuit of sonic excellence.

The ARES 15th: Redefining the DAC Standard
The ARES 15th embodies a new benchmark in digital-to-analog conversion, combining state-of-the-art audio engineering with meticulous craftsmanship. Its performance transcends expectations, delivering music with breathtaking realism. From deep, authoritative bass to smooth, richly textured mids and pristine, transparent highs, every nuance is revealed with absolute precision. The result is an immersive and unforgettable listening experience that sets a new standard in its class.

True Balanced R-2R Architecture with Upgraded Internals for Analog Sound

For years, DENAFRIPS has been celebrated for its mastery in designing R-2R digital-to-analog converters. The Ares II—recently renamed the Enyo—earned widespread acclaim in the audiophile community for its natural, analog-like sound. Building on that legacy, DENAFRIPS now unveils the Ares 15th R-2R, a next-generation, fully balanced NOS DAC that raises the bar for performance and precision.

The most significant advancement over its predecessors is the integration of dual LPNO (Low Phase Noise Oscillator) clocks, engineered to deliver exceptionally low jitter for purer, more lifelike playback. But Denafrips didn’t stop there—careful refinements to the power supply design and other critical engineering details ensure that every nuance of the music is faithfully reproduced.

The result is a DAC that embodies Denafrips’ relentless pursuit of audio perfection: the Ares 15th R-2R DAC, where digital artistry meets analog soul.

Engineered With Hand-Matched Resistors and FPGA Signal Processing

The DENAFRIPS Ares 15th R-2R employs a true balanced 24-bit R2R + 6-bit DSD architecture, engineered to deliver a natural, analog-like listening experience. Supporting up to 24-bit/1536kHz PCM and native DSD1024, it offers remarkable versatility for high-resolution playback.

At its core, the conversion stage utilizes 480 precision resistors controlled by an Altera FPGA for impeccable accuracy. Power delivery is equally robust, featuring a 60VA O-core transformer wound with UP-OCC copper, eight independent LDO regulators, and a bank of premium capacitors. Together, these refinements ensure exceptional clarity, precision, and tonal richness—redefining what a DAC in this class can achieve.

At the heart of the R-2R architecture lies its most critical component — ultra-precise resistors. The DENAFRIPS Ares 15th R-2R employs 480 high-quality resistors with 0.01% precision, painstakingly selected and matched at additional cost to achieve exceptional accuracy. Each resistor is meticulously handpicked, machine-calibrated, and verified under human oversight to maintain uncompromising quality and minimize thermal distortion.

This meticulous engineering ensures absolute consistency in signal conversion, resulting in a more natural, musical sound. Complementing this resistor network is a high-performance Altera FPGA (Field Programmable Gate Array), dedicated to Digital Signal Processing. Together, they form the foundation of the Ares 15th R-2R’s ability to deliver an organic, transparent, and emotionally engaging listening experience.

mproved Linear Power Supply And Ldo Regulators

Deliver Jitter-free Audio

The DENAFRIPS Ares 15th R-2R features an enhanced Linear Power Supply, integrated with a custom capacitors bank branded ‘DENAFRIPS,’ all crafted to precise audio specifications. Alongside constant current LDO Linear Regulators, a substantial heatsink is securely affixed. To meet the power demands of the FPGA, modular USB module, and balanced R-2R Ladder Networks, eight multi-stage LDO Linear Regulators are utilised. DENAFRIPS goes a step further by hand-winding the oversized 60VA O-Core transformer, meticulously adding multiple layers of UP-OCC copper shielding between the windings to effectively reduce electromagnetic interference (EMI) and electromagnetic fields (EMF).

Designed for Scalability with Flexible Connectivity

The DENAFRIPS Ares 15th R-2R is built with versatility in mind, housed in a precision-machined anodised aluminium chassis, available in both silver and black finishes. Compact yet robust, it elevates the solid build quality of the original Ares with thoughtful refinements.

This latest version introduces an I²S input for seamless integration with DENAFRIPS DDCs and other high-performance digital transports. Both the front and rear panels have been redesigned for intuitive operation and expanded connectivity.

On the front panel, dedicated buttons now provide instant access to USB, Coaxial, Optical, I²S, Oversampling/NOS mode, Phase inversion, and Mute. The rear panel offers balanced XLR and single-ended RCA analogue outputs, alongside USB, Coaxial, Optical, and I²S digital inputs—ensuring maximum flexibility for diverse system setups.
