Connecting us with the musical event
The absolute will breathe new life into
your audio les libraries; it is artifact free;
its linear circuit does not impart any audio
characteristics of its own.
• The device is fully balanced throughout –
a topology that helps minimize the noise
oor to vanishingly low levels (~-140dB)
• The Absolute can operate in single-ended
and balanced modes without any loss of
signal either way.
• Ultra-linear circuitry and hand-selected
and matched-to-circuit components are
used throughout.
• Contemporary, cutting edge technology
is applied in the Absolute design: we
choose the latest, highest performing
digital-to-analogue conversion
technology.
• Future-proof: modular construction for
both the digital input and analogue
output, which allows for easy updating as
necessary.
• Proprietary circuit design optimizes the
performance of the state-of-the-art DAC
chip and clocks used inside. Three ultra-
low jitter clocks are used to support sonic
precision and sound stability.
• Proprietary, ultra-low noise, dual-quattro
voltage parallel analogue amplication
stages implemented in the Absolute:
◊ Protects against noise, hum, and signal
degradation. Hence, signal accuracy
is unparalleled!
◊ Ample energy reserves, strikingly
improved SNR ratio. Stunning dynamics
are achieved!
• The extraordinary stable output stage
contains vast power reserves and is
therefore more than capable of driving
any commercially available pre & power
amplier combo, as well as longer cables,
both in single-ended and balanced
operating modes.
• The Absolute DAC’s main power banks,
both boards and components, are
engineered to ensure ultra-high operating
stability and precision, thereby negating
uctuations to subsequent stages.
• Proprietary power supply design provides
independent power lines to each stage
that bypasses the main power boards
and ensures insulation from internal noise
interference.
• The massive, hand-milled aluminum
chassis enhances mechanical stability
and provides shielding from airborne
vibration. The base alone has more than
1650 cubic cm of solid aluminum.
• A choice of digital lters allows the user to
optimize reproduction or, more simply, to
match the user’s personal taste.
• The Absolute DAC does not introduce
non-linear distortion even when operating
from a cold start; however, the sound
improves signicantly after the rst half
hour of operation.
Burn-in: based on our experience, the
absolute needs a little over 300 hours to fully
come into its own. Nevertheless, be assured
that the musical enjoyment begins from the
very rst moment!

DAC please read the brief instructions that
