      Item Condition: 7/10 Shipping Options: Pickup available and you can audition.,Shipping is available at agreed cost. Suburb or Town: Dalkeith State: Western Australia Payment Method: Paypal Friends and Family, EFT, Cash Reason for selling: NLR Moving on this gorgeous sounding Pre Amp I intended to keep, but I've decided I prefer the functionality of my other pre amp so no need to have this collecting dust.
       
      I am clearing out a couple of things to make way for some other toys I can use with my main gear.
       
      There are a couple of chips in the paint on the handles, I thought I would take them off and drop them to a powder coater who'll charge $25 to do them but I just dont have the time during the day at the moment.
       
      It is a lovely sounding unit.

      What Hifi 5 Star rating
      "The pricey DAC 8 is one of the most organic-sounding digital products we've
      heard"
      "Wonderfully big, authoritative, refined presentation; mighty bass; top
      class refinement; solid build"

      -accept signals up to high-resolution 24Bit/192kHz level
      -inputs optical, coaxial and USB are here, accompanied by the rarer BNC and
      AES/EBU alternatives.
      -outputs include RCA and balanced

      From the Audio Research 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.

      Price Range:  Please get in touch to discuss pricing
      Item Condition:  Very Good 
      Extra Info:
      Looking to try out a Valve Pre-amplifier in my system.  Looking for a LS5 Mk2 that is in 240 volts, not really fussed about the colour Black or Silver will do. Currently using a BP26 with MPS2 Power Supply.
