In the realm of high-fidelity audio, the quest for the ultimate digital-to-analog converter (DAC) is an ongoing pursuit. Two contenders that have garnered considerable attention are the Denafrips Ares II R2R DAC and the Topping D90. Both devices boast exceptional technical specifications and promise to deliver pristine sound quality. In this comprehensive comparison, we will delve into the intricacies of these two DACs, examining their features, performance, and value proposition to determine which emerges as the superior choice for discerning audiophiles.

Design and Build Quality

Denafrips Ares II R2R DAC: The Ares II is a meticulously crafted device that exudes elegance and durability. Its chassis is constructed from a combination of aluminum and steel, providing both resistance to electromagnetic interference (EMI) and a substantial feel. The front panel features a high-quality OLED display, while the rear panel offers a wide array of connectivity options, including USB, coaxial, optical, and balanced XLR outputs.

Topping D90: The D90, on the other hand, adopts a more minimalist approach to design. Its chassis is made from aluminum, and while it may not be as visually striking as the Ares II, it is still well-built and offers a solid foundation for the internal components. The front panel is dominated by a large volume knob and a small LED display. The rear panel provides a similar range of connectivity options as the Ares II.

DAC Architecture

Denafrips Ares II R2R DAC: The Ares II employs a discrete resistor-ladder (R2R) DAC architecture, which is renowned for its natural and musical sound. R2R DACs use a series of resistors to create a precise analog output signal, providing exceptional linearity and low distortion. The Ares II features a proprietary R2R ladder design with ultra-low noise and high accuracy.

Topping D90: The D90 utilizes a more traditional Delta-Sigma (ΔΣ) DAC architecture. ΔΣ DACs use a high-speed digital filter and a feedback loop to convert digital data into an analog signal. While ΔΣ DACs typically offer higher resolution and dynamic range than R2R DACs, they can sometimes exhibit a more analytical and clinical sound.

Sound Quality

Denafrips Ares II R2R DAC: The Ares II delivers a truly exceptional sonic performance. Its R2R DAC architecture imparts a natural and musical tonality, with a rich and detailed soundstage. The midrange is particularly impressive, offering a warm and inviting presentation of vocals and instruments. The treble is extended and airy, revealing subtle nuances and harmonics. The bass is deep and impactful, providing a solid foundation for the overall sound.

Topping D90: The D90 also offers a high level of sonic performance. Its ΔΣ DAC architecture provides excellent resolution and dynamic range, resulting in a detailed and precise sound. The treble is crisp and clear, while the midrange is articulate and well-defined. The bass is tight and controlled, providing a solid foundation for the rest of the frequency spectrum.

Features and Connectivity

Denafrips Ares II R2R DAC: The Ares II offers a comprehensive range of features and connectivity options. It supports high-resolution audio playback up to 32-bit/768 kHz PCM and DSD512. The device also features a built-in headphone amplifier with adjustable gain, making it suitable for driving a wide range of headphones.

Topping D90: The D90 provides a similar set of features and connectivity options as the Ares II. It supports high-resolution audio playback up to 32-bit/768 kHz PCM and DSD512. However, the D90 does not include a built-in headphone amplifier.

Value Proposition

Denafrips Ares II R2R DAC: The Ares II is a premium DAC that commands a higher price than the Topping D90. However, its exceptional sound quality, build quality, and feature set justify the investment for audiophiles seeking the best possible listening experience.

Topping D90: The D90 offers a more affordable option for those who want a high-performance DAC without breaking the bank. It provides excellent sound quality and a wide range of features, making it a great value proposition for budget-conscious audiophiles.

Which DAC is Right for You?

The choice between the Denafrips Ares II R2R DAC and the Topping D90 ultimately depends on your individual preferences and budget. If you are seeking the ultimate in sound quality and are willing to pay a premium for it, the Ares II is the clear choice. However, if you are looking for a high-performance DAC at a more affordable price, the D90 is an excellent option that will not disappoint.
