HIGHLIGHTS
The DAC chip adopts the latest AK4499 released by AKM in 2019; DSD adopts the native direct solution mode, and the DSD digital stream does not pass through the internal digital filter and works in NOS mode, which is fully in line with the design concept of HQPlayer.
It has a wealth of input and output interfaces, including standard USB2.0 input interface, SPDIF and BNC coaxial and AES balanced input, HDMI-I2S input interface, analog output including XLR balanced output and RCA single-ended output; all interfaces support DSD input.
SDA6 PRO supports external clock input, among which USB supports 10M clock input, and other interfaces support WCK input. In USB mode, it also supports adjustable input impedance of 50 and 75 ohms.
The high-end version requires manual adjustment and production, so it takes more time to ship. Among them, the high-end version adopts a non-loop negative feedback full DC full-balanced discrete Class A output circuit; the crystal oscillator of the USB part uses a CCHD-957 femtosecond clock; the analog part uses a Mundorf film capacitor for tuning; the sound performance will be A little more relaxed and lively.
MAIN FEATURES
- Self-developed adaptive clock system technology, built-in 4 independent ultra-low jitter audio crystal oscillators, equipped with a femtosecond-level local clock system for the USB part, the standard version of the crystal oscillator is AS-318B, the pro version is CCHD- 957.
- High-performance digital-analog hybrid phase-locked loop, excellent clock synchronization recovery technology, can greatly filter the secondary PLL of external digital input jitter;
- It adopts 4 channels of fully balanced and full DC discrete circuit output; among them, the high-end version adopts non-loop negative feedback output;
- Large-scale FPGA for digital audio signal processing, self-developed second-generation algorithm, original multi-input channel isolation technology, to ensure the purity of each input signal.
- Built-in 40 watt custom O-type transformer, output 4 independent power supply windings, up to 20 groups of distributed voltage stabilized circuits; among them, the reference power supply provided for AK4499 is the newly developed ultra low noise (as low as 0.5uV RMS) power supply system.

Electrical standards
1. The USB input socket is a standard USB-B type female socket, and the USB power supply range is 4.5V-5.1V;
2. The SPDIF interface inputs standard S/PDIF signals, the input impedance is 75 ohms, and the AES input impedance is 110 ohms;
3. The power input is 115V/230V AC, and a 40-watt customized transformer is used for power supply;
4. I2S input is LVDS level in the form of HDMI interface, compatible with most front-end equipment.
SPECIALIZATIONS I2S over HDMI
- HDMI LVDS 3.3V differential signal;
- HDMI LVDS 3.3V differential signal; I2S interface compatible with a number of I2S output signal definition, FPGA built-in PCM / DSD signal automatic identification algorithm;
- DSD ON signal self-detecting, DSD ON this signal can be hard input to the PIN13,14,15,16 pin.
- PIN1-3 and PIN7-9 phase adjustable, the Default user can configure the phase
- The SDA-1 can be configured with SW switches to accommodate different I2S standards.
HDMI-I2S is different for each manufacturer worldwide, and for most manufacturers HDMI-I2S is a proprietary proprietary protocol. Default is PS-Audio standard.
USB COMPATIBILITY
- Windows 7, Windows 8, Windows 10; 32/64 bit (Windows driver included)
- Native MacOS 10.6 and later, using the system comes with drivers
- Native Linux with UAC2 compliant kernel, using the system comes with drivers (tested on Ubuntu and Daphile systems, based on INTEL X86 platform)
- Android OS 4.2 and above, need equipment to support OTG function, in general, Android 5.0 system is supported by default, the following recommendations for 5.0 with a dedicated player.

Aleksei –
I have owned a SINGXER – DAC – SDA 6 PRO for 3 months and after 20 hours of warm up, it played great. and this piece of gear has been a tremendous change on my system . After that, I have to raise the level of the vinyl player (buying a new one) in order to somehow catch up with the level of sound that SINGXER produces. And I don’t see it as a problem. Congratulations to the MAGNA HiFi team.
Excellent service. High level of product knowledge, good communication, fast shipping, perfect package protection and top tracking information

Super DAC – I’m really happy so far!
The DAC can very well convert 48k integer rates into DSD (e.g. 3.07MHz with DSD64).
It says so in the documentation for the AK4499 and also makes the SDA-6 perfect.
Excellent!

The best DAC I’ve ever owned (Rega, Project RS / 2, Denafrips ARES II). Detailed, musical, free of any distortion – truly fantastic. Highly recommended !!!
Louis (verified owner) –
Nice compact DAC with excellent sound properties. Wonderfully musical, hours of listening a real pleasure! Use especially the USB input and it is really top class. Happy with it, also with the SA1. Nice set together!
