CORDA DACCORD
The DACCORD is a state-of-the-art Digital-to-Analog converter with integrated crossfeed and volume controlled outputs.

One of the main purposes of the DACCORD is to provide maximum sound quality for as little as money as possible. Therefore this converter has no fancy enclosure and its appearance is relatively slim.

However, inside two top-of-the-line Wolfson D/A converter chips in dual-mono mode, a large battery of audiophile capacitors, ultra-fast opamps in class-A, high-precision oscillators (TCXO's) and many other very high-quality components are found that are exemplary for this price-class.

Two coxial, one optical, as well as an USB-input allow for easy connection of any digital source, including your computer. A variable output allows to directly drive a poweramplifier or a pair of active loudspeakers.

The converter uses the newest Wolfson WM8804 S/PDIF receiver chip which, instead of a conventional analog PLL, uses its own separate high-precision quartz-clock. Thus much higher jitter reduction can be achieved then with more traditional receivers.

A unique feature of the DACCORD is the built-in extended natural crossfeed-filter. Whereas the functionality of the natural crossfeed filter as found in our headphone amplifiers is limited to frequencies upto around 800 Hz this new filter has a much wider bandwidth and now covers the whole range from DC..2000 Hz in which the human ear is sensitive for directional information. The result is a more stable imaging when the crossfeed is activated whilst listening by headphone.
