pre-owned DAC1541
InquireOur high performance single ended DAC with builtin powerfull Headphones Amplifier, based on the well tested and renoved Soekris R-2R technology. The dac1421 has the same features, performance and quality as the top end dac1541, just without the balanced signal chain.
It have the fantastic clean and natural sound of a 27 bit R-2R sign magnitude DAC, built with over two hundred tiny and very precise thin film resistors. The line output buffer is a high performance 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 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.
