Introduction
The Soekris dac2541 is a fully balanced Audiophile discrete R-2R DAC, with USB and SPDIF
inputs and outputs to either the built in headphones amplifier on a front mounted XLR or 6.3mm
Jack, or to line level outputs on rear mounted XLR and RCA Phono connectors. The dac2541 is not
just any regular DAC, the sound quality is the absolute best available, thanks to the ultra high end
design with a discrete R-2R sign magnitude DAC using a total of over 200 small and very precise
resistors, powerful hybrid headphones amplifiers, delivering high power to almost any headphones,
all powered by high reliability switch mode power supplies with post LC filtering and two discrete
linear low noise and low impedance power regulators and three low noise regulators for the digital
parts.
The dac2541 R-2R DAC circuit is fully isolated from the noisy computer USB interface and the
SPDIF inputs are also all transformer isolated. It supports input signals on the USB interface up to
24 bit / 384 Khz PCM audio, and up to DoP-128 (x2) and DSD-256 (x4) audio, or up to 24 bit / 192
Khz PCM audio on the various SPDIF interfaces. It has a fully digital volume control and four sets
of digital reconstruction filters to fit any taste, and have a flexible crossfeed circuit for the
headphones. The dac2541 is designed and built in Denmark, using advanced surface mount
technology and parts from only the highest quality suppliers, with a full aluminum casing.
