note: WIN7 users may have issue if you don’t have the most recent hotfix for SHA-256bit code signatures. By default Win7 only supports SHA-1 signatures, yet SHA-1 is obsolete and this hotfix is very important for security reasons. Win 8 and above have SHA-256bit by default. Some users reported these drivers not installing properly, so be sure your Win7 is up to date, or download the hotfix here (KB3033929) :

Cyan PCM version will be available early May 2018 to ship. so Cyan PCM orders have a longer wait, however will be 2week average after May. Our production is resuming on the PCM and accepting orders now for shipments in May. PLEASE take note of this information. Cyan DSD orders will ship approx 1.5-2week from order.

“NOTE:  Please email us and we can take care of your questions. This DAC is in very high demand and quite hard to find in the USA. HoloAudio and KitsuneHiFi are working together to provide you these products although after importation costs they are only slightly higher pricing than what is found if purchasing direct from China. Please take note that ONLY 220V is available when purchased direct from HoloAudio in China or other sources. HoloAudioUSA/KitsuneHiFi has exclusive rights to sell the 110V/220V switchable model. We also can custom make other Transformers like 220, 230, 240v etc”


Product Description:

The newest HoloAudio offering is the Cyan Dac/Amp. We have worked hard to bring you the best performance and price ratio of any product on the market. We are quite proud of the Cyan and confident in saying we think you will find it most impressive as well. It’s a true balanced discrete resistor ladder dac with balanced headphone amp packed into a small footprint of desktop space. There is a PCM module version and a DSD module version.

DSD is natively supported on this Discrete Resistor Ladder DAC

Holo Audio is the world’s first to support DSD natively on Resistor Ladder DAC, so far the only one. This is not the DSD converted to PCM before digital-analog converter, but directly by the discrete components of the DSD digital to analog converter. Supported currently on MAC (DOP)and Linux (DOP), and Windows/PC (Direct Native and DOP). Please note, the word ‘R2R’ is the name of a kind of architecture of resistor ladders. This architecture requires less resistors yet still is capable to deliver more than acceptable performance. Most DACs in the industry use this architecture. The DSD module of Cyan does not use R2R architecture for the DSD, more specifically it uses a very specific architecture which is optimized to perform DSD to analog. So to be entirely accurate the DSD module of the Cyan is using resistor ladders, not R2R.

For those who choose the PCM module version you will be able to enjoy the balanced headphone amplifier. However if you choose the DSD module version then you will not be able to use the headphone amplifier. For those who know DSD well, they will know that pure DSD does not allow for volume control. In fact if a DSD dac claims to have volume control then you will know that it’s first converted to PCM internally to achieve this.  We released the pure DSD module version for those looking to have a unique and high performance Discrete resistor ladder dac DSD solution. We have highly optimized the architecture of our resistor network to have an incredible sounding DSD dac. if the Amp was enabled it would be at 100% volume and put your ears and headphones at risk. Also the DSD version will have a “headphone delete” and not contain the components on the motherboard for the headamp. However there will still be a volume control knob and headphone outputs on the front panel that will not function.


Here at Kitsune, we have three versions of the Spring DAC. Other places ONLY offer two models. Below are the three models:


HoloAudio Cyan – PCM Edition

PCM Module (Balanced) has full function Balanced  headphone amplifier that is capable to power most any headphone and sensitive IEM. Has high and low gain settings to fine tune the amp for whatever pair of headphones you may have.  28bit pure PCM module with digital volume control. 

HoloAudio Cyan – DSD Edition

Pure DSD Module (Balanced) – Headphone Amplifier “delete” – no internal amp. External knob and headphone out connectors are still visible but have no purpose. This is a DSD Dac only.   

HoloAudio Cyan – Enthusiast Edition

Some of us find it really difficult to choose one of the above configurations so we have a solution that is essentially a special edition that is based on the PCM module Cyan however it also includes a DSD module that you can swap out when you choose. The firmware on the dac module with automatically disable the onboard headamp to prevent any damage to hearing or headphones. This Enthusiast Edition will have some extras and final details will be announced Mid December.


Cyan’s input and output interface:

  • Digital input interface includes
  • USB (ground isolation)
  • RCA coaxial
  • BNC coaxial
  • AES
  • optical fiber
  • I2S (HDMI)
  • All digital input interface supports DSD (DOP mode).

Cyan’s Outputs:

  • Fully balanced/bridged XLR and RCA output
  • Balanced headphone output using 4 pin xlr

Other Notes:

• Offers oversampling and non oversampling modes
• Compact chassis 11inch* 10.25inch * 2.15inch
• The new fully balanced headphone circuit capable of powering most any headphone easily
• Ability to select either low impedance or high impedance for the headphones and to change this easily
• Includes high quality aluminum remote control – functions include: Mute, Volume, low & high gain for Output, Input Selection, Display Brightness, OS/NOS mode

For SRC, you can refer the following chart

Mode Input Format Internal SRC
Cyan – PCM NOS mode PCM No SRC
DSD Convert DSD to PCM
OS mode PCM Oversampled to 352.8K or 384K PCM
DSD Convert DSD to PCM
Cyan – DSD NOS mode PCM Convert PCM to DSD
OS mode PCM Oversampled to DSD256
DSD Convert PCM to DSD

The true balanced circuit design

These two pictures can explain the true balanced design quite well. And showing the architecture of the PCM module vs the DSD module. The bottom side has the same resistor ladders as top side. The dac module is a pure 28bit discrete resistor ladder design. extra bits to acommodate digital volume control.

outpute stage: XLR uses all of the circuit and RCA is just using half. The balanced output has better performance (THD, noise) and also better common mode rejection rate. If you’re listening environment contains interference, either from AC power or from EMI/RF then you will find a full balanced system can really help significantly.

    This Dac/Amp is wonderful to my ears…it has a sweet tone and sounds fantastic!

    I purchased the PCM balanced version and I can’t get over how good the built in amp is!

    The build quality on this machine is “Japanese Marantz” level….maybe even better!

    Get one!

    One word. Wow! Going from the Mytek Stereo 192 DSD to the Cyan DSD (Roon upsamples everything to DSD512) is to me a game changer. Soundstage depth, speed and transients, delicacy, analogue sound… Can’t stop listening to music for the last 2 days.

    And Tim offers great service!
