What HFL Thinks
Chord Blu MKII - I think it is fair to say that there is no other audio brand out there quite like Chord Electronics, offering highend audio products with unique styling and stunning build quality which are all hand built in the UK in rural Kent. Possibly best known for their DAC’s they also offer a range of highend components. With customers like Skywalker Sound, Air Studios, and Even Sir Paul McCartney on their books along with stunning reviews that their equipment gets you can be sure that Chord really do offer some of the best products currently available today. So whatever you are after please pop into HFL to find out how Chord Electronics can enhance your music listening.
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.
In More Depth:
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. Our 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 BNC S/PDIF digital input, meaning that it can also be used a standalone 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.
