General Information

Sabaj Da3 HI-Res amplifier using the second generation XMOS USB Audio solution - XCore200XU208.PCM sampling rate support up to 32bit/768kHz, and up to DSD512 supported.Exclusive customized driver supported native DSD which is very advanced in audio range.

Using two pieces of ultra-low phase noise crystal as an asynchronous clock system, make the sound is more accurate, resolution is higher.

MCU control and electronic volume control ensures two channels output volume is exactly same, while the phase is also absolutely balanced.

Two ultra-low noise LDO power respectively and independently for left and right channel amp.Stable voltage enables amp chip works and act it's stable function;the Ultra-low noise ensure the chip out of interfered from the power supply for purer sound.

Full balanced design and Using two SABRE9018Q2C decoding chips from ESS company in USA.Support high bit rate digital processing;Ultra High Dynamic Range;built-in big-power amp circuit, ultra-low distortion can restore a better sound;Dual DAC&circuit for better channel separation.

The output uses a silent circuit to protect the headset from impulsive sound distory ,while greatly reduces the loss of audio signal.

0.96 inch OLED display screen,the interface is simple and easy to operate.

Specially designed 2 headphone output jacks,3.5mm UNBAL&2.BAL.

NOTE: We do not recommend DA3 connected mobile phone use, because DA3's power consumption is designed by the computer, if the phone's load capacity is not enough, it can not be used, if the phone is not protected, there is even the possibility of damage to the phone!

The DA3 features fairly simple and plain packaging. On the front there is the company logo, model name, and Hi-Res logo. On the back you have some contact information and that’s about it.

On the inside it is not much different, you just have the DA3 and the cable.

Simple and straightforward.

Design & Build Quality

The DA3 is constructed of aluminum and has a foam pad on the bottom side. This pad acts as a non-slip surface and allows the DA3 to grip to the surface it is placed on. The overall body slightly tapers down. When looked from profile, you can see it is a very slight upside-down trapezoid. However, when you look at it from a bird-eye perspective, you can also notice that it it also tailors towards the bottom.

The general design is quite minimalist and there isn’t a whole lot going on. The busiest part is the top side. On the upper top side of the DA3 there is a “Sabaj” print. This print isn’t very clean, there is a fade around the letters, which makes it look a bit funny. This “glow” is also present on the “DA3 Audio DAC” print on the bottom-right corner. On the lower part of the top side there is a small OLED screen, and right below it there are three buttons. The left/right buttons are -/+ volume buttons or menu down/up, while the one in the middle changes the display mode (menu).

The first menu will display the sample rate and the volume. On the second menu you can switch between BAL (2.5mm) or UNBAL (3.5mm). On the third menu there are three filters you can choose from: Fast Rolloff, Slow Rolloff, Minimum Phase. And, on the fourth menu you can choose if you want a timer that will turn off the display (5, 10, 15, or 20 seconds), or you can turn off the timer entirely.

And that’s about it.

Performance


The overall performance was quite good. It had no issues driving power hungry headphones like the planar-magnetic HifiMan Deva or the Dekoni Audio Blue, but there also was no noise present in more sensitive headphones (iBasso SR2) and IEMs. When comparing it to the EarMen Sparrow (which also has a 3.5mm SE and a 2.5mm BAL output), the DA3 seemed slightly thinner in sound — but note that the Sparrow is also slightly more expensive and thus would make up for the price difference.

I am personally shocked that I didn’t need to increase the volume above 25% on all of my headphones and IEMs. It really makes me wonder which headphone or IEM would be pushing this thing to its limits.

It was only later that I realized that not only can you adjust the volume on the DA3, but also on your laptop/PC. I had it on 100% on my laptop, and then I only adjusted the volume on the DA3 — much like you would do when you connect an AMP to a DAC that has volume control (you set the DAC to the max and increase/decrease the volume on the amplifier).

Pairings (% represents the volume value on the DA3)

Dekoni Audio Blue 25%
SIVGA P-II 20%
Sennheiser HD6XX 23%
Hifiman Deva 21%
Jade Audio EA3 10%

2.5mm Jade Audio EA3 6%

Conclusion

I am happy to say that I was pleasantly surprised by DA3’s performance. I did not expect it to have so much headroom in terms of power, and I definitely did not expect to not encounter any noise at all. It is a perfect budget DAC/Amp for desktop use or portable use. One thing to take into consideration is that it is not designed to be used with smartphones. You should also be careful carrying it around due to its “sharp” edges, you want to make sure it does not damage whatever you are carrying it around in.

This is a great $120 DAC/Amp, at least it proved to be from my personal experience.

Plenty of power, huh?

@InvisibleInk At least from my experience. Things don't exactly add up since no source I own can drive the planars and the 6XX at 20%.
