Chord Electronics QDB 76 DAC New QBD76 the world's most technically advanced DAC Building on the huge success of the award winning DAC64 the QBD76 is now able to take digital to analogue conversion to a new level with improvements in performance and sound reproduction not seen anywhere else.
Chord produces another world’s first technology.
Chord Electronics has once again produced the world's most technologically advanced DAC. Building on the huge success of the award winning DAC64, the QBD76 now takes D/A conversion to a new level of performance not available in any other product. In addition a unique Bluetooth digital audio receiver allows users to stream high quality music wirelessly from a Bluetooth enabled phone, PDA or PC.
Instead of simply using the best off the shelf DAC chip, Chord actually designed their own using the newest Xilinx field programmable gate arrays. This state-of-the-art development platform provides Chord engineers with a staggering 1,250,000 logic gates with which to design their DAC.
This level of capability was undreamt of only a few years ago. By comparison the best DAC chips available today use only 30,000 logic gates. Thus, with over 40 times the development power, Chord engineers were able to control every aspect of their DAC’s design and performance. As a result, the QBD76 is capable of resolving 40dB more data than DACs using the best off the shelf chips. This remarkable improvement takes the QBD76 very near the theoretical limit for CD audio, and once again Chord emerges with technology literally years ahead of the competition.
"Remember, although the DAC64 was Stereophile's 2007 Product of the Year, and awarded A+ Recommended Component in 2007, it is actually eight year old technology! Imagine the improvements in digital technology over the past eight years. Better yet, don't imagine, go hear one today! With it’s new design and updated WTA algorithm, the QBD76 achieves a signal to noise ratio greater than 120 dB, a dynamic range of 122dB, and, remarkably, less than 3pS clock jitter cycle to cycle. The QBD76 has astounding resolving power and is better able to reconstruct transient edges than the DAC64. This results in substantial improvements in: timing, imaging, soundstage depth, pitch reproduction and bass definition.
Usability has been improved with the addition of a display and control via a microcontroller circuit. Input selection, phase and RAM buffer settings can all be changed using three buttons on the top panel. Configuration is clearly visible via the magnified display. There are two coax, two AES, two optical, one USB and one Bluetooth A2DP input.
" This is the very best DAC I've heard to date...
it's obvious that Chord's new QBD76 is in a gang of one. Dramatically musical yet devastatingly revealing sound makes this unique product the definitive digital to analogue convertor right now." - Hi-Fi World, Sept. 2008
