Description
This new DAC “Spring3” is the design that has been very popular since 2016. This is another milestone for Holo Audio’s owner 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 (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 II²S 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.
L1
(The base model is quite good all by itself and priced so competitively it’s impossible to beat the performance/price ratio.) This model has basic caps for the PSU, and does not include a CNC remote. It has standard Red label 5N Copper Otype Transformer, round wire type copper wiring. Considered the base model however packs a mean punch for price per dollar performance ratio. (no remote control in this version)
L2
(With HoloAudio caps for ultimate power filtration and improved sound quality – Sound quality is refined and more relaxed, transparent and details are more refined and clear while remaining neutral. ) It has standard Red label 5N Copper Otype Transformer, round wire type copper wiring. This is a popular option for those who want a little more out of their dac with improvement of sound from the caps as well as this version will include the cnc machined aluminum remote control.
L3 (same as KTE in US) on top of L2 spec:
- 100VA O-type (NOT toroid) Flat wire type as found in the flagship May Dac L2 and KTE.
- All copper wire is replaced with 1.5mm pure occ silver wire
- Hand Selected Dac module to have best measurements compared to averages.
- Enhanced USB module same as May L2/L3 dac. Has Titanis 2.0 circuit.
- Replaced IEC inlet connectors with pure silver/rhodium plated faston connectors at the IEC inlet
- HoloAudio Red Nano fuse
- Holo Audio Caps(factory have done extensive testing and these prove to provide the very best sound quality)
What are the Spring 3’s sound characteristics? :
One of the strong points of the spring is the spatial sounds stage presentation. It’s very wide and precise. It never sounds congested like many DACs. The high end is very detailed and never harsh sounding. It has the R2R goodness that many have come to know and love. Everything comes effortlessly for this DAC. Bass is layered and textures, quite full and present without ever masking over the sweet mid tones that are produced. One special thing about the Spring is its amazing voltage regulation circuitry that better than 0.2uV output noise! This along with the O-core transformer helps regulate the purest power which translates to audio clarity and accurate reproduction. It must be heard to appreciate and come to love its sound.
