Chord BLU MKII Upscaling CD Transport


Request A Price Match

The Chord BLU MKII Upscaling CD Transport provides better  CD sound quality by using the very latest FPGA technology to implement advanced proprietary filtering and upscaling techniques. It'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). The BLU MKII is equipped with the Xilinx FPGA, which take it to an unprecedented 1,015,808 taps - the technical indicator of how complex the interpolation filter is.

Various inputs and outputs are available and the BLU MKII also features a USB digital input, meaning that it can also be used as a standalone high-performance upsampler, for use with other digital sources. It includes a proprietary high-frequency switching power supply and a dedicated CD-only laser mechanism for uncompromising performance.
