Entry Level Discrete R-2R Sign Magnitude DAC

We might call it entry level, but there is absolutely no entry level about the technology and sound quality on this little gem. Based on the well tested and renoved Soekris R-2R technology, just a little smaller that its bigger siblings and without the headphones amplifier, but otherwise with the same performance and quality.

It have the fantastic clean and natural sound of a 26 bit R-2R sign magnitude DAC, built with two hundred tiny and very precise thin film resistors, with high quality output buffers. The main power supplies are ultra low loise, low impedance and very fast.

The music is delivered over an USB interface in both PCM and DSD formats, or by the SPDIF or Toslink inputs. It is then buffered and reclocked using a precise and very low jitter oscillator, with the digital processing done in a programmable FPGA chip, with a set of selectable advanced digital filters and a digital volume control.

Technology that used to be reserved to a few DACs costing the same as a car. But now thanks to smart Danish design and automated manufacturing in Denmark it will be available at a much more reasonable price.
