dac1541
High End Discrete R-2R Sign Magnitude DAC / HeadAmp
Our highest performance fully balanced DAC with builtin powerfull Headphones Amplifier, based on the well tested and renoved Soekris R-2R technology. This is the best available, with the highest performance and quality.
It have the fantastic clean and natural sound of a 27 bit R-2R sign magnitude DAC, built with over four hundred tiny and ultra precise thin film resistors. The line output buffer is a high performance fully balanced zero feedback design built with discrete parts, the buffer also have a high power mode to drive any set of Headphones. The main power supplies are ultra low loise, low impedance and very fast, also built with discrete parts.
The music is delivered over an USB interface in both PCM and DSD formats, or by the SPDIF, AES or Toslink inputs. It is then buffered and reclocked using a precise and ultra 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.
