OFFICIAL Signed Windows Drivers v4.67.0 +all Firmwares Win7/8/10 ASIO- HERE – improved performance
NOTES for new v4.67 Driver (this is a major release with firmware update for each model, Spring2 (two versions), Spring1, Cyan DSD or PCM.
* New usb driver, v4.67 +firmware updates ALL models. XU208 chipset
* Spring2 new usb firmware 30.12 (significant improvement of USB performance, and recommended for those using Motherboard USB (intel/amd)
* Spring2 new usb firmware 30.14(only support up to pcm768k and dsd512). This firmware can be worked with those ‘hifi’ PCIE usb cards (JCAT PCIE Femto (renasas chipset), Linear Technologies PCIE Femto card, Matrix Element/ElementH USB card (texas Instruments).
* Spring Version 1 – new usb firmware 21.16. This fixes the problem roon has mentioned before, which has problem while switching between 24bit and 16bit at same sample rate.
* Cyan PCM or DSD – new usb firmware 21.06. This fixes the problem roon has mentioned before, which has problem while switching between 24bit and 16bit at same sample rate.
All new firmware must have installed the new 4.67 USB driver first. and then copy the directory of the firmware contents into the driver folder… commonly found in programfiles/holoaudio/USB Audio Device Driver/W10_x64/
then run the file “holousbaudioDfu.exe”
BE SURE you copied the appropriate firmware for your dac. (be sure no USB devices are between your source and the dac during firmware update. only usb cable.)
V1 and V2 spring are very different.
take note version 30.14 are for those with either JCAT Femto PCI-E card (renasas chipset) or the Matrix Element or Element H card (texas instruments chipset)
these are LIMITED TO DSD512 and PCM768 at this time.
MOST COMMON upgrade firmware – version 30.12 is for motherboard USB chipset which is commonly Intel base USB controller and should support DSD1024 and PCM1.536Mhz as stated above in overview.
Spring V1 firmware is only one choice and has no issue with Jcat or Matrix USB cards, so no worries here. both Spring V1 and Cyan have known issue with Roon where changing from 24bit and 16bit sample rate can cause a problem. this is now fixed and addressed in the new firmware update.
ALL these new firmware updates improve USB transfer eye pattern in a significant way! there is a significant reduction in emi noise during USB transfer, and this means theoretically improving sound quality. Measurements confirm whether one can hear the difference or not.
Cyan PCM and Cyan DSD orders will ship approx 3-3.5 weeks from time the order is placed.
“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”
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.
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.
Cyan’s input and output interface:
- Digital input interface includes
- USB (ground isolation)
- RCA coaxial
- BNC coaxial
- optical fiber

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.
