Holo Audio SPRING 3 DAC Level 1
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.
DSD is natively supported this R2R Discrete DAC. In fact these are two separate DAC’s, noe does DSD and one PCM. Completely separate to achieve highest results. Holo Audio supports DSD natively on R2R DAC. Impressive technology resulting in excellent sound quality, benefit true capabilities of DSD. 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).
Holo Audio SPRING 3 LEVEL 1 DETAILS
- 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, “泉3” Spring3 (non preamp model) 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.
- Optional (Factory installed only): A fully balanced, fully discrete analog pre-amplifier. Provides 84 steps, each step is 1db of volume control.
