Product Description:

This new DAC “Spring3” is the design that has been very popular since 2016. This is another milestone for HoloAudio’s own Jeff Zhu. It’s a full discrete R2R type of audio decoder and does not have off the shelf-DAC chip! This is a bespoke custom-designed core DAC module and truly a breakthrough with technology for any DAC chip today. Trickle down technology from the Flagship May Dac. The Spring3 is here to achieve new heights, new dynamics and simply a full spectrum of audio to please the aural senses.

Features:

A new generation of linear compensation technology. A better solution to the resistance, accuracy errors caused by switching components and PCB, after compensations makes the equivalent accuracy reach 0.00005%.
The new generation of de-glitch technology can provide a full range without increasing the noise floor or other adverse effects.
Based on this new generation of technology, Spring3 can provide a SINAD of >112dB and a dynamic range of >128dB, which represents the performance limit reached by today’s most advanced R2R architecture DAC.
Using the ultimate performance of PLL+FIFO technology, provides 0.1Hz Third-Order low-pass ability to inhibit jitter. It also uses a high-performance femtosecond VCXO as the PLL clock source. Under the premise of being almost immune to the front-end jitter, it can also lock up to 1.5us-2us @ 1KHz signal with high jitter. (It can lock up to 1.5us-2us @ 1kHz signal with high jitter on the premise of almost being immune front-end jitter).
The USB interface uses proprietary firmware with ultra-low latency, a highly reliable data transmission, ideal USB eye pattern measurements that contributes to 2-4 times higher performance than official firmware.
A single, independent HDMI-I2S input interface is provided, which has a four-way independent circuit, as opposed to standard LVDS chip, making I2S clock signals subject to lower interference and lower jitter. In addition, the I2S input can be configured with a specific pinout configuration, making it compatible with most of the HDMI-I2S digital devices on the market.

A fully balanced, fully discrete analog pre-amplifier. Provides 84 steps, each step is 1db of volume control.

The highest grade components are used in our very popular KTE version products. This Spring3 KTE version will include an upgraded ultra premium transformer that is 100VA O-Type flat wire type .The sound improvement is not subtle, it’s a night and day improvement in our opinion and many of our customers agree. Kitsune has tuned this Spring 3 DAC for no compromise performance and targeted at the enthusiast audio lover. This transformer is our finest available model and makes the Spring’s sound quite elegant and improved detail. more features mentioned below.

Fully discrete and balanced relay controlled volume control. Controls all the digital inputs volume with precision. This has trickle down technology from our popular flagship Preamp the Serene. Using 4 amp modules and hundreds of transistors.

This DAC was carefully implemented with some of the finest components.
The following is added to KTE Spring3:
1. 100VA O-type (NOT toroid) Flat wire type as found in the flagship May Dac L2 and KTE.
2. All copper wire is replaced with 1.5mm pure occ silver wire
3. Hand Selected Dac module to have best measurements compared to averages.
4. KTE Spring3 is ONLY level to have the enhanced USB module as found in our L2 and KTE May dac. Has titanis 2.0 circuit.
5. Replaced IEC inlet connectors with pure silver/rhodium plated faston connectors at the IEC inlet
6. HoloAudio Red Nano fuse
7. Holo Audio Caps(we have done extensive testing and these prove to provide the very best sound quality)
8. Special Kitsune Tuned Edition branding inside and out (pure copper Kitsune fox emblem on top panel, like our extremely popular KTE SU2 product)
9. KitsuneHiFi VIP service, english support and manuals/software
