CD, DAC & Media Players -

The Blu MkII is a compact, FPGA-based upsampling CD transport which offers the world’s most advanced filter technology. Used with DAVE, the combination delivers class-leading CD sound quality and technical performance.

Put simply, the Blu MkII upscaling CD transport sets new standards for CD sound quality by using the very latest FPGA technology to implement advanced proprietary filtering and upscaling techniques. Chord's next-generation CD transport incorporates a powerful new FPGA core with extraordinary capability.

Blu MkII’s sophisticated WTA (Watts Transient Alignment) filtering and upscaling algorithms can output digital data at 705.6kHz (16 x CD’s 44.1kHz native resolution). When partnered with the critically acclaimed DAVE DAC/preamp, with its 705.6kHz-capable digital inputs, the Blu MkII sets a new technical benchmark for CD performance, while redefining sound quality from the medium.

At the heart of the Blu MkII lies an enormously powerful Xilinx FPGA. Rob Watts’ (Chord’s Digital Design Consultant) has used this to create his exclusive WTA M-Scaler technology, which incorporates the most advanced filter of its kind in the world. The Xilinx FPGA has also enabled a key breakthrough in tap-length (the technical indicator of how complex the interpolation filter is) taking Blu MkII to an unprecedented 1,015,808 taps.

A comprehensive suite of high-performance connectivity is offered and the Blu MkII also features a USB digital input, meaning that it can also be used as a stand-alone high-performance upsampler, for use with other digital sources.

Further features include Chord Electronics’ legendary proprietary high-frequency switching power supply and a dedicated CD-only laser mechanism for an uncompromising performance.

Available in Black or Silver.
