I'm selling my reliable and great sounding Benchmark DAC2 HGC DAC/Preamp because I recently upgraded to a Lyngdorf TDAI-3400 and no longer need a separate DAC/Preamp.  The item comes with the Original Box, Remote, Manual, Power Cord, and after-market basic USB cord.  
This is a phenomenal sounding DAC and I've own every Benchmark product that has come out since 2003 with the original DAC1, DAC1-USB, DAC2-HGC and have enjoyed their sound for many years.  It's very detailed sounding, but it's not analytical or fatiguing to listen to and it's dead quiet on all inputs.
The Benchmark DAC2-HGC itself is 9/10 condition, but 7/10 on the remote only because the anodizing has worn off the back of the aluminum remote control in places (see picture), but it functions just fine. A new remote can always be ordered from Benchmark for $99, but like I said this one functions just fine. 
Will be shipped FEDEX in the original shipping box, insured, to your confirmed PayPal address.

  • A NEW REFERENCE - GOING BEYOND THE LEGENDARY DAC1

    Benchmark's DAC1 family of D/A converters 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. The DAC1 has been the best-selling 2-channel reference-quality converter and is in daily use at many of the finest recording studios and mastering rooms. DAC1 converters are also enjoyed by thousands of audiophiles. Benchmark has raised the bar ... the DAC2 defines a new reference.

    REFERENCE PERFORMANCE

    The DAC2 is Benchmark's new 2-channel D/A converter. The DAC2 converter has lower noise and lower distortion than Benchmark's DAC1 converter.The performance of the DAC2 exceeds the measurement limits of some of  today's best test equipment.

    The DAC2  delivers outstanding musical detail and precise stereo imaging. It employs an advanced high-headroom digital filter design, and a new high-sample-rate Asynchronous USB Audio interface. All inputs are fully isolated from interface jitter by Benchmark's new UltraLock2™ 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 converter are summed together to create each balanced analog output. This 4:1 summation provides a 6 dB noise reduction, and gives the DAC2 industry-leading performance.

    NATIVE DSD CONVERSION

    All digital inputs on the DAC2 support native PCM or DSD 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 DAC2 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 and DAC2 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 overemphasised. 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, DAC2 converters are ideal for critical reference-quality professional systems. Unlike many competing products, the DAC2 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 DAC2.

    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. 

    DESIGNED, ASSEMBLED, AND TESTED IN THE USA

    This Benchmark product was designed, assembled, and tested in the USA using USA and imported components. Most major components are made in USA.
