The Sabaj DA2 is surely the tiniest and lightest DAC I’ve ever used and does feel a bit flimsy.

It kind of makes the DragonFly Red/Cobalt, FiiO BTR3K, and Centrance DACport HD look and feel gargantuan in comparison.

The interface is incredibly simple; there’s a + and – for volume, and an LED indicating what type of file you’re playing.

Blue means pretty much anything up to 32-bit/768kHz, and DSD will display purple/magenta.

On the top, there’s your standard 3.5mm jack, and the bottom reveals a micro USB port.

The DA2 utilizes an ESS Sabre 9018Q2C DAC chip and has an output impedance of about 0.4 indicating you’re going to get a very clean signal.

There’s really nothing more to it than that.

How does it sound in relation to what I have on my desk?

Let’s compare.

In going back and forth between these 2 for a couple of hours, I found the differences to be subtle but definitely noticeable.

The DragonFly Red provides more slam, weight, and impact; particularly to bass notes.

Overall, it’s more of a grand, open affair, and portrays the music in a more crisp, vibrant light; something I’ve talked about quite a bit with the DragonFly Red and why I tend to recommend it so often over the 60+ Amps & DACS I’ve heard at the time of this writing.

The DA2 by contrast feels a bit more relaxed, laid back, but kind of lacking a bit of energy.

It sounds great, but the soundscape isn’t quite as tight and snappy.

It also feels more closed in on Jazz tracks like this version of John Coltrane’s Afro Blue. The Red is definitely more open sounding with more air.

Keep in mind the difference is fairly marginal but can be heard on certain tracks.

Tei Shei and Blood Orange’s “Even If It Hurts” is a great example of the bass sounding a tad better on the DragonFly Red.

With the DA2, it feels a bit foggy and lacks some impact.

slenderbodies’ “Anemone”, a track I’ve heard hundreds of times, sounds more forward and lively with the DragonFly Red; especially in regard to the hazy, almost incoherent vocals.

The song itself envelopes you the listener just a bit more.

At the end of the day, the differences between these 2 are still pretty subtle.

  • Weight: 0.8 oz / 23.5 g

The differences between these 2 are even more subtle, but they’re still there.

The DA2 is ever so slightly more neutral and clean.

It’s just a smidgen crisper, similar to that of the relationship between BTR3K and DF Red.

The BTR3K dons a somewhat warmer flavor, but both sound very similar at the end of the day.

The DA2 is just a tad more articulate a bit less glossy. Both go incredibly well with the Koss KPH30i; one of the players in this demo.

So as for a hierarchy of how these 3 sound, the DragonFly Red is the most neutral, followed by the DA2, and then the BTR3K.

Sabaj DA2 Amp/DAC Review

As for my personal preference?

I would lean towards the BTR3K or DF Red, but in reality, it’s very close.

The DF Red does tend to do a better job of separating instruments and sounds; something I’ve always touched on in reviews and videos.

The DA2 isn’t far behind in this regard but does sound more claustrophobic by comparison.

Even so, I like the DA2’s package.

It comes with a USB Type-A to micro, a USB Type-C to Type-C, and a Micro to Micro.

I can easily pair it with my phone and be off to the races. Plus it’s around $150 less.

To be honest, this is the first portable DAC I’ve found to work seamlessly with my dinosaur LG-X Charge phone, but I’ve since upgraded to an iPhone.

I mostly listen to music on my desktop but found the DA2’s 3 cable options incredibly convenient.

A lot of companies don’t include as many which can be really irritating.

Out of the 3, I do think the BTR3K presents the best overall value, as you can use it Bluetooth or on your desktop charged full time.

It’s the easiest to transport and move around with, something I really don’t care to do with many other DACS.

You’ve also got the balanced 2.5mm option and it can take calls.

The downside is that the 3k doesn’t have as much power as the others, so if you do plan to listen mostly on your desktop with more demanding headphones, I’d go with something more powerful.

I would say go with the DragonFly, but I don’t recommend it anymore as it’s overpriced in today’s climate.

For a replacement, look here at my best portable options.

The DA2 does support higher sampling rates, but I’ve talked at length about how it doesn’t really matter in my What Is DSD In Audio? and What is MQA?! articles.

In reality, anything above 44 or 48kHz is largely inconsequential.

Final Verdict

The Sabaj DA2 is a pretty decent DAC, but my recommendation for most people is a Bluetooth DAC with plenty of power while remaining portable enough for on-the-go, but is also great if you just want to plug it into your computer and use it on your desktop.
