Audio Research Dac8 In great shape. works great and of course sounds amazing! has every digital input imaginable. SPDIF over RCA, Coax or Toslink, AES/EBU XLR input and even USB! how cool is that. talk about the ultimate Computer Soundcard WOW! From the ARCDB website. We are pleased to introduce the new DAC8 digital to analog converter. Although physically similar to its predecessor, the DAC8 represents new engineering that advances the state of the art in high resolution USB audio and S/PDIF audio. Audio Research has maximized the USB capability of the DAC8 by incorporating USB 2.0 HS (High Speed) which runs at 480Mbps. USB 2.0 HS has a lower jitter specification than USB 2.0 FS (Full Speed 12mbps), consequently the DAC8 is capable of reproducing music at higher definition/resolution (up to 24/192) than products communicating at USB 2.0 FS speeds (24/96). In addition, the DAC8 employs a low jitter Dual Master Oscillator design that will provide superior digital to analog conversion via its USB 2.0 HS input as well as via the more traditional S/PDIF (RCA, BNC, Toslink and AES/EBU) inputs that are also included on the DAC8. Our USB 2.0 HS audio interface is optimized for all six sample- rates currently in popular use; 44.1, 48, 88.2, 96, 176.4 and 192kHz. In the past, S/PDIF was the default interface mode for High Resolution music files at 176.4 and 192kHz. Now, with Audio Research’s Dual Master Oscillator, USB 2.0 HS interface, and our Quad D/A converter design, USB audio is finally elevated to the status once dominated by S/PDIF. Consequently, regardless of whichever digital input you select, the Audio Research DAC8 promises to provide a superior listening experience. In addition to the High Performance USB design, the DAC8 features: DAC8 HD Audio Device software drivers, which allow listening to your music in its native sample rate as well as assuring BIT PERFECT, low jitter, data transfer from the computer to your DAC8. Because PC and Mac operating systems do not adequately support sample rates over 96kHz, Audio Research has developed ASIO drivers to make the USB audio experience sonically transparent at all sample rates. Sample Rate measuring function: Measures and displays the correct digital sample rate being sent to the DAC8. This works in USB as well as S/PDIF mode. Consequently, at a glance, you always know exactly which sample rate is being decoded. The DAC8 employs four 24-bit D/A converters. Each channel uses dual 24-bit D/A converters running in mono mode to lower the noise floor and increase the dynamic range. Dual Master Oscillators: When the time base of any DAC is not an integer multiple of the digital music sample rate, decoding and quantization errors occur. Consequently, the DAC8 uses two low jitter Master Oscillators; one for 44.1, 88.2 & 176.4kHz sample rates and the other for 48, 96 & 192 kHz sample rates. The DAC8 automatically selects the correct Master Oscillator the instant digital music is detected at the selected input. All inputs are galvanically isolated from the source to reduce or eliminate noise and/or jitter from entering the DAC8. The Analog amplifiers in the DAC8 have received the same attention to detail as the digital section. Each channel of the DAC8 uses a true direct-coupled differential amplifier with a bandwidth in excess of 90kHz. The DAC8’s USB and S/PDIF inputs are designed to accept signals from an HRx, 176.4kHz, 24-bit, High-Resolution music server system playing HRx’s DVD-R recordings. See www.referencerecordings.com/HRxSETUPS.asp for recommended music server setups. By virtue of all of the above points and our proprietary software drivers, intrinsic jitter has been reduced to less than 10ps. DAC8 HD AUDIO DEVICE SOFTWARE DRIVERS: The DAC8’s USB driver software provides your computer with special high-speed audio drivers not supplied by MS Windows or Mac OS. The Audio Research USB drivers are specially designed to assure low jitter BIT PERFECT data transfer between the server/computer and the DAC8 at all sample rates. Our drivers setup the USB interface to guarantee bandwidth, independent of active bulk transfers from the hard drive. From the ARC icon in your computer’s input tray you can set the DAC8 to any sample rate from 44.1 to 192kHz and allow the music server/management software to up or down convert your music to the selected sample rate. Music lovers can use custom sample rate conversion algorithms or other file formats provided by third party suppliers such as Windows Media Player, iTunes, J Rivers Media Center, Media Monkey, FooBar, and many others to optimize your music experience. The DAC8 is a fully balanced, zero-feedback, solid-state design utilizing a direct-coupled FET output stage with generous regulated power supplies and seven stages of regulation. There are separate new digital and audio power transformers, and the board material is the same as what we use in our Reference products. Dynamic, forceful, immediate, and possessing remarkable resolution and transparency, the DAC8 is a sonic knockout that is worthy of the finest music systems. With a choice of high-resolution 24/192 S/PDIF inputs (RCA, BNC, AES/EBU and Toslink) in addition to the highest resolution 24/192 USB available, the ability to adjust sample rates, the DAC8 provides the new standard in high performance digital music playback.

The worlds largest online retailer of pre-owned audio Product DescriptionWho we areWhat we doOur ProcessOur Policies Audio Research DAC8; D/A Converter (No Remote) Product SKU: 63702 Age: 8 Years Tobacco Exposure: No MSRP: $4995 Serial Number: 80305517 # of Owners: 1 Service History: None Cosmetic Description: Good cosmetic condition with some minor visible cosmetic wear including a nick in the top edge of the faceplate, some other smaller nicks around the edges of the faceplate, and a few small nicks on or around the back edges of the unit. This item does show a few blemishes, but is attractive overall and has been well cared for. What is Included: DAC, Manual, Power cable (Remote Not Included) Other Notes: Note: The USB DAC is compatible with PC with appropriate drivers installed and Mac OS systems before El Capitan but not after. Remote is not included with this unit. Instrument focus and precision within this expansive sound stage is spot-on. And, importantly, the overall cohesion the thing that ties together the instrumental strands and makes the whole make musical sense isnt lost. In terms of outright authority and low-frequency power, the DAC 8 need fear no rival: it sounds as solid and muscular as they come. There is always a danger that products which excel at smoothness and refinement will end up sounding pedestrian when asked to replay something thats packed with energy. Thats not the case here. Playing a rough and highly charged recording like Polices Roxanne, this converter responds with vigour. It delivers a sound with all the attack and drive the song deserves. - What Hifi?
