Chord Electronics a British HiFi manufacture, develop award-winning proprietary processes without compromise; technology at the apogee of its game. They are unapologetically unique: they don’t follow convention, they provide extraordinary sound and a mechanical design to suit your lifestyle.

As with all Chord Electronics products, their avionics heritage inspires only the highest quality: all of their products start life as a single billet of aircraft-grade aluminium. This is just one of the hundreds of processes that help shape their multi-award-winning devices; the same standards, care and attention run through the production of all of Chord electronics units.

When you place an order for a device in the Table Top range and above, your purchase is assigned to an engineer who will begin the process of curating each individual component before carefully crafting the unit to the highest standards. Only once it has passed numerous measured and listening tests, will it qualify for a Chord Electronics name badge. Naturally, this is a bespoke process that takes time, however, during your products’ build, you are more than welcome to ask your retailer any questions that you may have.

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 USB digital input, meaning that it can also be used as 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 uncompromising performance.
