Next Generation Wadia - 
the sophisticated series 5, 581 and 581i; the first entries in a new
family of multi-format Wadia Disc players.Wadia 581i Disc Player
Feature Multi-Format Stereo Audio Playback, New Digital to Analog
Technology and Other Sonic Enhancements for CD’s, SACD’s, and
High-Sample Rate Sources
The Wadia 581i  Disc Player featuring digital inputs and outputs is
built with the classic Wadia quality and aesthetic, advance the
performance of the now legendary 861 decoding circuit and add
multi-format stereo audio playback capabilities. The 581j Disc Player
represent true innovation from Wadia and signal the company’s
commitment to provide customers with expanded features and superior
sound.
New and Updated Technology Throughout – New design features include a
multi-format capable transport, an advanced proprietary software based
DSD Processing Algorithm that generates bit corrected SACD playback
and 6 new Circuit Topologies. Wadia SwiftCurrent™ 2 Discreet (SC-2D)
allows for superior current to voltage (I/V) conversion. Traditional
Wadia technologies such as DigiMaster™, ClockLink™, and DirectConnect™
with Digital Volume Control have been updated for the new players.
Improvements to the main decoding circuit include a new master
clocking scheme, time coherent analog filter array,  and a superior
grounding scheme. Greater current capacity and improved filtering
provide improved power onboard the main decoding circuit. 
New Multi-Format Disc Mechanism – Modified to allow ClockLink jitter
reduction and pure data capture, this new multi-format mechanism
provides state-of-the-art audio information extraction. No less than 6
patent worthy technologies ensure that data is accurately captured
from audio discs regardless of format. The mechanism is further
enhanced by a custom mounting and enclosure system that provides both
mechanical and electrical isolation. Performance of this mechanism
surpasses even the highly acclaimed 3.2 transport featured in previous
players. 
DigiMaster – The patented DigiMaster filter system is optimized to
preserve the subtle time and phase information vital to musical
realism. Dual digital processors running DigiMaster software (release
2.5) attain 24-bit resolution at sample rates in the millions.
SwiftCurrent 2 – SC-2D technology, a powerful proprietary circuit
introduced in the Wadia PowerDAC Digital Amplifier, has now been
re-invented. To exploit the extraordinary data rate generated in the
digital section a discreet implementation of our patented current
mirroring technology was created. Current exiting the D>A converters
is now optimally loaded, in turn allowing each DAC to remain linier.
Current is then mirrored and driven with a zero global feed back Class
A throughput stage. The output feeds directly into a phase accurate
filter that simultaneously creates voltage and removes unwanted high
frequency noise.
Wadia DirectConnect Technology with Digital Volume Control –
DirectConnect allows the Wadia 581, and 581i Disc Players to be
connected directly to a power amplifier, bypassing the losses inherent
in analog preamplifiers. 
ClockLink Jitter Reduction – ClockLink eliminates jitter-inducing
clock transmission by locating the master clock at the DAC instead of
the transport. The result is significantly reduced jitter and markedly
improved sonic performance. 
High-Power Zero Noise Supply – 30x the reserve capacitance required is
available for DC current supply from the all new switching power
supply board. The switching frequency at .5 Mega-Hertz ensures that no
noise approaches the pass band. Filtering was upgraded and the outputs
fully isolated to insure no noise contamination.
Upgradeable Modular Design – Upgrade flexibility is a cornerstone of
Wadia’s philosophy. Software-configured circuitry, along with modular
design such as digital outputs, 24-bit digital inputs as featured on
the 581i, ensure that the Wadia series 5 Disc Players can be upgraded
to accommodate future technology.
Sonically – The Wadia 581 and 581i Disc Players draw the listener into
the music with spacious 3-dimensional images, instantaneous
transients, and remarkable liquidity of sound. The Wadia 581 Disc
Players offers a higher level of musical realism than any Wadia disc
player previously available.
