Astell & Kern - CD Ripper MKII
Astell & Kern
Chords all new Blu MK II CD Transport is by far the worlds best up-sampling CD player available. It uses Chord's famous FPGA technology to implement proprietary filtering and upscaling techniques. Pair this with the Dave DAC and you have the best sounding digital rig in the world.
Here is the rest of the info from Chord:
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 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.
