We can offer customers wishing to upgrade their existing Chord equipment generous trade in allowances. Other manufacturers equipment is also considered.

Chord Electronics' flagship DAC can also be purchased with DSD decoding capability. The QBD76HDSD enables users to enjoy high-quality DSD downloads, to get closer to the music than ever before. Existing 'HD' models can also be upgraded to HDSD status. Contact your us for more details.

Updated to include a new High Definition 192KHz capable USB interface the QBD76 HD is the latest edition in our hugely successful digital to analogue converter range. With the emphasis for high quality music now strongly focussed on computer downloads, the QBD76 HD allows you to take full advantage of this 192KHz high definition data. 

The high definition USB input replaces the existing Bluetooth circuitry and uses a special high speed data connector where the existing Bluetooth antenna was fitted. A special USB 2.0 certified full data rate cable is provided to allow connection to a computer. The existing USB input is still useable for CD quality playback giving the option for two simultaneous USB connections for both high definition and standard definition playback from the same DAC at the same time.

The digital design of the QBD76 HD from digital input, to the DAC outputs, is designed using the latest generation of field programmable gate array devices (FPGA), now with 1.25 million gates. The FPGA handles the switching of SPDIF inputs, all digital SPDIF decoding, digital PLL, RAM buffer controller, WTA filtering, and the 5th generation Pulse Array DAC. All of these functional blocks are designed at the gate level, for maximum performance. The HD USB input uses its own separate FPGA and features asynchronous USB technology isolating the digital clocks from the computer. Each sample rate clock is generated discretely using highly accurate crystal oscillators for optimum performance and ultra low jitter performance. Proprietary USB driver software is provided removing the restrictions of current operating system audio playback. It also gives very easy setup and sample rate selection from 44KHz to 192KHz allowing for upsampling of standard definition music.
