Benchmark DAC3 HGC HiResolution DAC
Benchmark DAC3 HGC HiResolution DAC
Benchmark Media Systems are a well known company in the profeesional audio recording and mastering world - they are engineered to the highest standards and are designed to be ultra low noise, ultra low distortion and thus deliver more of EXACTLY what is in whatever music is being played through them. In the early days of digital audio many HiFi buffs and audiophiles cottoned on to using the same technology as the professionals - so te original Benchmark DAC became quite a classic - superb engineering and sound for a reasonable price... well now in the DAC3 HGC there is a reference grade DAC with professional sound and specifications that continues the legacy.
A NEW REFERENCE DAC from Benchmark
The DAC3 is Benchmark's newest 2-channel D/A converter featuring the new ESS Technologies ES9028PRO converter chip. The DAC3 converter has lower THD and THD+N noise than Benchmark's DAC2 converter.
Benchmark's DAC1 and DAC2 D/A converter families have been the reference to which other converters have been compared. It is rare to find a converter review that does not draw comparisons to the DAC1 or the DAC2. Benchmark converters are in daily use at many of the world's finest recording studios and mastering rooms. Benchmark converters are also enjoyed by thousands of audiophiles. Benchmark has raised the bar again ... the DAC3 defines a new reference.
REFERENCE PERFORMANCE
The DAC3 delivers outstanding musical detail and precise stereo imaging. It employs an advanced 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 new UltraLock3™ jitter attenuation system.
Internal digital processing and conversion is 32-bits, and this processing includes 3.5 dB of headroom above 0 dBFS. This headroom prevents the DSP overloads that commonly occur in other D/A converters.
Four balanced 32-bit D/A converters are summed together to create each balanced analog output. This 4:1 summation provides a 6 dB noise reduction, and gives the DAC3 industry-leading performance.
NATIVE DSD CONVERSION
All digital inputs on the DAC3 support native 192 kHz PCM or DSD64 conversion. From any input, DSD is transported with bit accuracy over DoP 1.1. DSD and PCM are both natively converted to analog. There are no DSD to PCM or PCM to DSD conversions to compromise the quality of the music. The DAC3 conversion system seamlessly switches between native PCM and native DSD conversion. DSD over DoP 1.1 is supported by many media players, and DSD downloads are now available from several sources.
DIRECT CONNECTIVITY TO POWER AMPLIFIERS
Benchmark DAC1, DAC2, and DAC3 converters are designed to directly drive power amplifiers and speakers. Benchmark converters feature adjustable low-impedance passive attenuators at the XLR outputs that can be used to optimize the interface to the power amplifier (or powered monitor). This unique Benchmark feature optimizes the gain staging between the DAC and the power amplifier. Proper gain staging cannot be overemphasized. When audio stages are properly matched, each component in the audio chain is able to operate at its optimum signal level, and the system performance is significantly improved.
SONICALLY-NEUTRAL STUDIO MONITORING
All Benchmark converters are designed for maximum transparency. This transparency is absolutely essential in the studio monitoring chain. For this reason, DAC3 converters are ideal for critical reference-quality professional systems. Unlike many competing products, the DAC3 is not designed to add "euphonic" coloration to the audio. Instead it is designed to be as uncolored and natural as possible.
STEP INTO THE STUDIO
When Benchmark's professional converters are used in hi-fi applications, studio-quality sound can be enjoyed in a home environment. Enjoy pure music without any coloration from the electronics. Hear the music exactly the way it was heard in the studio, and exactly the way the artists intended.
Discover the natural, uncolored, analog sound of the DAC3.
SIT IN THE PERFORMANCE SPACE
Transparent sound can go beyond replicating the studio experience. Recordings that have been produced with a natural and unprocessed sound can transport you to the performance space. But, this can only happen when the entire playback chain is selected for maximum transparency.
This experience of "being there" cannot be created by systems that are designed to add "warmth" or "euphonic color" to the music.
