Benchmark DAC3 L – Silver – Stereo Preamp/ PCM & DSD D/A Converter/No Headphone Amp w/remote control

Introduction

The Benchmark DAC3 L is the latest innovation in Benchmark’s esteemed line of digital-to-analog converters (DACs), building upon the legacy of the acclaimed DAC1 and DAC2 models. Incorporating the advanced ESS Technologies ES9028PRO converter chip, the DAC3 L delivers unprecedented levels of audio clarity and precision. This detailed guide explores the features, technological advancements, and performance enhancements of the Benchmark DAC3 L, establishing it as the new reference in high-fidelity audio.

Benchmark DAC3 L Overview

The Benchmark DAC3 L sets a new benchmark in the world of digital-to-analog conversion. It surpasses its predecessors, the DAC1 and DAC2, with significantly lower Total Harmonic Distortion (THD) and THD+N noise, thanks to the integration of the latest ES9028PRO converter chip. This converter is celebrated for its use in many of the world’s finest recording studios and mastering rooms, and it is now available to audiophiles seeking the highest quality audio reproduction at home.

Key Features and Benefits

1. Superior Audio Performance

The DAC3 L is engineered to deliver exceptional musical detail and precise stereo imaging. It features a high-headroom digital filter design and a high-sample-rate asynchronous USB audio interface. All inputs are fully isolated from interface jitter by Benchmark’s UltraLock3™ jitter attenuation system, ensuring a clean and accurate audio signal.

2. Advanced Digital Processing

Internal digital processing and conversion are executed at 32 bits, with an additional 3.5 dB of headroom above 0 dBFS. This headroom prevents DSP overloads that are common in other DACs, maintaining the integrity of the audio signal.

3. Balanced Analog Outputs

The DAC3 L employs four balanced 32-bit D/A converters summed together to create each balanced analog output. This 4:1 summation reduces noise by 6 dB, providing industry-leading performance and a more refined listening experience.

Technological Innovations

1. Harmonic Compensation

The ES9028PRO chip includes two distortion compensation systems that independently remove most of the 2nd and 3rd harmonic distortions. Benchmark’s clean analog output stages fully leverage these systems, resulting in the lowest THD among D/A converters.

2. Hybrid Gain Control (HGC)

Benchmark’s unique Hybrid Gain Control combines active analog gain control, passive low-impedance attenuators, a 32-bit digital gain control, and a servo-driven volume control. This sophisticated system ensures precise control and transparency, maintaining the natural sound of the audio without coloration.

3. UltraLock3™ Jitter Attenuation System

The UltraLock3™ system provides virtually perfect jitter attenuation with a locking time of just 6 ms, compared to 400 ms in previous models. This improvement eliminates any audible jitter artifacts, delivering a pure and accurate sound.

Improved Features Over DAC2

The DAC3 L includes several enhancements over the DAC2, such as:

• Active 2nd and 3rd harmonic compensation
• Lower THD+N and passband ripple
• Improved frequency response and faster PLL lock times
• Enhanced switching between input signals

Enhanced Connectivity and Usability

1. Native DSD Conversion

All digital inputs on the DAC3 L support native 192 kHz PCM or DSD64 conversion. The DAC3 L seamlessly switches between native PCM and DSD conversion, preserving the original quality of the music without any compromise.

2. Direct Connectivity to Power Amplifiers

Benchmark DACs are designed to directly drive power amplifiers and speakers. Adjustable low-impedance passive attenuators at the XLR outputs optimize the interface between the DAC and the power amplifier, enhancing the overall system performance.

3. Home Theater Integration

The DAC3 L can be seamlessly integrated into home theater systems, offering features like Home Theater Bypass, which sets the pass-through gain to unity when the surround system is active. This allows the DAC3 L to drive the left and right power amplifiers while integrating with the home theater system.

Studio-Quality Sound at Home

Benchmark’s DAC3 L is designed for maximum transparency, making it ideal for critical reference-quality professional systems. This transparency allows users to experience studio-quality sound in a home environment, hearing music exactly as the artists intended.

Cutting-Edge Technology

The DAC3 L incorporates several cutting-edge technologies, including:

• Harmonic Compensation: Reduces 2nd and 3rd harmonic distortions.
• UltraLock3™ Jitter Attenuation System: Provides fast and accurate jitter attenuation.
• High-Headroom DSP: Handles signals as high as +3.5 dBFS, preventing clipping and distortion.
• Quad 32-bit Balanced Conversion System: Delivers superior audio quality with reduced noise and distortion.

Conclusion

The Benchmark DAC3 L represents the pinnacle of digital-to-analog conversion technology, offering unmatched audio performance and a host of advanced features. Whether used in professional studio environments or high-fidelity home audio systems, the DAC3 L delivers an unparalleled listening experience, setting a new standard for audio excellence.
