Waversa DAC3 fully loaded with new updated logic board - The MKII. $4000

Recommended Posts

This unit is effectively new. The dac chips will require burn in time. There are 4 modular bays that allow addition of various inputs. This unit will have have your choice of: Coax, Ethernet, AES, Optical, secondary modular clock. USB is built into the chassis. Ethernet is highly recommended. Price is firm but a reduce price may be offered with fewer modules. This is a 50% price reduction. Email regarding provenance. Since Waversa Systems is not well known in the US, I offer a 1 month trial period with full refund if the unit is returned in new condition. Buyer is responsible only for initial and return shipping. I prefer the owner enjoy what this unit offers and it fits well in their system. I do not own the remote for this DAC as this is a separate purchase and I have no need.


Review: https://www.oldnewsound.es/fuentes/dacs/waversa-wdac3/


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.


Key Features of the DAC3:


The Waversa DAC3 has many special features. Waversa Systems’ digital features include:

⦁ Dual mono ES9018K2M SABRE 32 Reference Audio DAC chip set for D/A conversion

⦁ Dual Waversa Audio Processor (WAP) Chip set

⦁ 44.1, 48kHz implemented as a complete system Unified Clock System composed of independently-specific MEMS Master Clock

⦁ Real-time PCM to DSD 256 conversion using a custom built 5.6 MHz up-sampler and FPGA DSD converter

⦁ DSD to PCM Upsampling (world's first)

⦁ PCM Enhancement: Bypass, 1x, 2x, 4x, 8x

⦁ Custom built, FPGA based, 1.5 MHz up-sampling then conversion to 384 KHz for D/A processing.

⦁ All digital inputs and a customized S/PDIF receiver accommodating rates up to 192 KHz (so long as the source is S/PDIF compliant – see “Operation”)

⦁ A UAC2 standard compliant custom audio interface design, with Cypress FX2/FPGA USB input handling:

⦁ DSD 64, DSD 128

⦁ PCM 44.1 KHz, 48 KHz, 88.2 KHz, 96 KHz, 176.4 KHz, 192 KHz, 352.8 and 384 KHz.

⦁ Operations via Linux OS with UAC2 and MAC OSX 10.6, with the Thesycon driver incorporated for use in Windows OS environments

⦁ Optional in and out reference word clock connectors for use with an external clock

⦁ Complementary Full Balanced Analogue Circuit

⦁ Discrete / Transformer output mode can be selected

⦁ Output Voltage Control: 100%, 75%, 50% to adjust output gain and refine sound depending on individual system.

⦁ Select equipped with digital inputs and outputs, modular (up to 4)

- Ethernet Network Player, Coaxial, AES / EBU, Optical, Word Clock Input, Accessory Clock Module options, Bluetooth, Wi-Fi, headphone amplifier, analog input

⦁ Cutting duralumin chassis, and internal block reducing vibration and improving RF and galvanic isolation.

⦁ The digital portion and analog portion are independently powered using dual toroidal transformers, each with duralumin isolation and independent linear circuitry.

⦁ Front LED display (1,800 LED): source, the input sampling rate, menus, artist, song, etc.

From the manufacturer:


This DAC is over engineered and has continuous upgrades allowing for new settings, filters, codec processing, and internet streaming. New Firmware update allows ROON streaming of native files into their Ethernet port using Airplay. ROON RAAT software inside the DAC3 is custom build with unique partnership between Waversa and ROON. ROON RAAT places low CPU demand in the DAC3 renderer. Many Waversa users in Korea feel it is better because for this very reason produces less noise.

With modular design, versatility comes at a nominal cost. Three soon to be released new modules are the 24 bit bluetooth broadcast Apt-X HD BT audio module. WiFi module and 256 GB SSD module.

With the anticipated release firmware update next month the DAC3 will be 4xDSD.
