Waversa Systems Inc. DAC3 New to North America

Introducing the Waversa DAC3 MKII, which is marketed in North America as the Waversa DAC3.  Up for sale at at a greatly reduced price are thee units BRAND NEW redesigned circuitry, ie the MKII.  The only thing origional is the external chassis.  Five untis were presented to various reviewers.  After collaboration with Bascom King, a re-design was completed.  Collin Shin, the lead engineer and CEO of Waversa Systems wanted all dacs in the US revised to current specs.  
 
Waversa DAC3 Demo has a full one year warranty.  The DAC3 has 4 modular bays so is easily customized by the end user.  USB input in incorporated into the chassis.  Optional Modules include: AES/EBU, coax, Toslink, Ethernet, accessory clock and others.  Each module will be also offered at cost, $200.  The optional clock module is $400.   Email to inquire.  
 
Waversa has two types of remotes that are DAC3 compatible.  One is a universal remote for their product line, the other is just for the dac itself.  Each are built with the same dura-aluminum material as the chassis.  These can be special ordered.  

Units are offered with 30 day money back guarantee, minus shipping costs. Always audition gear to ensure the synergy in your system.  
 
Since the chassis has been briefly reviewed, the chassis may have a minor blemish.

As challenges that existed two decades ago remain today, electrical engineers specializing in digital sound reproduction face arduous task overcoming these barriers.    Digital audio technologies certainly have evolved to meet these challenges.  Out of South Korea, a company comprised of four engineers approached analog and digital from an entirely new perspective.  Introducing Waversa Systems Incorporated, founded in 2012 by Collin Shin, CEO and lead design engineer.  Dr. Shin has been acknowledged for many firsts in the computer electronics industry.  With 30 years of developing low noise, jitter canceling chips specific to both medical and military precision critical applications, he recognized these solutions when correctly implemented address these challenges individually, thereby allowing the listener to be enveloped by the music. Waversa DACs have been noted for their delicacy, revealing the fingertip-friction sounds on an instrumental string, or a flat cord on a note, better voice articulation and overall inner detail recreating venue ambiance with such holographic realism the musician can be perceived in the same spot when the listener wanders a room. I remain to find a dac that re-creates this level of timbre with such realism that naturally differentiates the uniqueness of each individual instrument when simultaneously paying the same note.

All DAC manufacturers have their own approach to address high frequency noise associated with pulse code modulation. Waversa Systems PCM processing is truly unique in today’s market. Waversa Audio Processor takes a completely unique approach to signal processing by comparing the signal simultaneously from multiple points in virtual space and time and superimposes this information creating a more precise signal reproduction, instead of artificially filling in information and unintentionally creating high-frequency noise that often is perceived as “cold digital sound.”

Unlike the traditional digital audio converters, Waversa uses their-own in house proprietary chip set that synchronizes with the neighboring internal processors, greatly reducing jitter. These Waversa Audio Processors (or WAP) consist of two parallel clocks (44.1 kHz / 48 kHz) thus creating mathematically accurate sampling at higher frequencies to 352 kHz / 384 kHz.

The DAC3 converts PCM to DSD in real-time when CONV (“Conversion”) is selected.  When conversion to DSD is selected, all PCM input samples are converted to 256 DSD via a custom built internal 5.6 MHz up-sampler and FPGA DSD converter.

The USB interface is implemented through network player hardware by Waversa Systems and is UAC2 standard compliant.  This provides an extremely clean digital audio signal through complete galvanic isolation, which strips the digital signal of any PC noise commonly created by a server’s internal power supply. Firmware updates and music data are also communicated through the single provided USB input. This is accomplished by a special interface, again unique to Waversa Systems.
