Now without further ado, let’s get rolling!!


Like most kids growing up in the ’90s, I was raised on Super Mario, Donkey Kong, Nickelodeon, and the Atlanta Braves.

Times were much simpler back then. We played outside. We got dirty. We rode bikes. We built forts.

Our parents took us to the lake and we rode Jet Skis. Our Grandparents had Beach Houses. We played with Legos. We played ball in the backyard. We went swimming at the neighborhood pool.

When we came inside from playing all day, dinner was ready and we watched the Braves on TBS for the nightcap before going to bed.

The next day we did it all over again.

If you were a youngster at this time, life was truly special. I don’t take it for granted at all.

I feel very blessed to have experienced those moments and will cherish them forever.

Of course,

Gaming headphones, Amps, DACs, and anything studio-related didn’t exist to us.

We weren’t so wrapped up in technology as to forget the beauty around us.

I think that’s lost on kids today.

Whereas technology might have accounted for 15-20% of our existence in the ’90s, I think it’s more like 80-90% for children growing up in this era of what I like to call “ready-made fun.”

The Good ‘ol days.

More often than not, kids are turning to technology to appease their fun appetites, and I believe it’s dangerous and will only get worse.

That’s not to say no one goes outside anymore, but it’s definitely becoming increasingly rarer. No pun intended.

Rare (or Rareware) was the company responsible for making the early versions of Donkey Kong for the Super Nintendo.

I said all that simply because having an Audioengine D1 as a Gaming rig makes me hearken back to simpler times when it wasn’t possible to use a headset to listen to music and the gaming environment.

We had a SNES controller and that was it. Even the games themselves were much simpler.

The goal was to reach the end of the level without getting obliterated.

I actually still have a Super Nintendo and from time to time play it for old-time’s sake.

If you think about what a video game entails nowadays, it’s truly mind-blowing and shows how far technology has come.

I feel blessed that I’m able to hunt for excellent sound quality, and today I’ll let you know if the D1 fits that criterion for an incredible price!

So.. how’s build on this puppy?

Build Quality

Audioengine D1


The build of the Audioengine D1 is stellar for the price. It feels like if you dropped it, it would be okay.

All of the connections are solid, and the volume knob feels sturdy and rugged.

If I had to nitpick, I wish the knob had some numbering (or engraved line) to let you know how loud it was being pushed. Something like an E10K and an HA-2 both have this feature.

The volume knob on the D1 does not have any indicators, so there’s no way of knowing where the sweet spot is.

Aside from that, this is about as simple and clean as it gets concerning its build.

No fuss no muss!

The power button also feels nice on your finger and pressing it is satisfying.

After pressing, it lights up white and isn’t harsh on your eyes like some other units.

Lastly, the headphone jack feels solid.

It may seem trivial, but you’d be surprised how many headphone jacks I’ve come across that don’t put your mind at ease with regard to how well the 3.5mm plug slides in and stays locked into the hole.

How about Features & Usage?

Features & Usage

Versatility for days.

As far as music-enhancing features go, it’s kind of bare-bones, to be honest.

No bass boost, and no gain switch.

I personally don’t mind it as I find the sound to be great on its own, but your mileage may vary.

It’s got a slight hint of warmth which sounds fantastic paired with an HD650.

  • A couple of options that do have those enhancement features are the Oppo HA-2 and E10K if you need something different.

If by features you mean its many uses, then it’s one of the best and most versatile in this price range or otherwise.

In the open, I quickly ran down some of those. Let’s delve into each one separately.

Powered Speakers

What’s cool about the D1 is that it’s a preamp; you can simultaneously connect it to speakers and listen with headphones, given its RCA analog outs and USB connection.

It leaves a tiny footprint on your desk as well.

Dedicated Amp/DAC

Plugging this in via USB will bypass your PC/Laptop’s internal Soundcard and provide you with a better conversion, but that depends on your PC/Laptop.

I remember the days of running a Lenovo T510 which contained one of the worst Soundcards of all time.

That said, newer products have come a long way in that most have very good internals. My Lenovo X1 Extreme improved tremendously in that regard.

Due to its AK4396 DAC and TI OPA2134 low noise opamp, the D1 will satisfy even the most demanding audiophiles.

The amp was designed for an array of headphones, and the DAC is very well regarded for its low noise floor, high fidelity, and precision.

Dedicated Gaming Rig

JDS Labs Objective 2 + DAC Magic 100

Here’s a really ghetto living room setup I was using to compare some Amps years back.

Because of its optical input, you’re able to use it with a PS4 or Xbox as well.

I heard a notable difference in sound quality vs. just plugging my headphones into the 3.5mm jack on the controller.

Dynamics, Soundstage, clarity, and detail are all improved to a startling degree.

Just watch out for that Super Mutant!


I docked a few points off for lack of listening enhancements, but overall it still gets a solid A.

What about Ergonomics? Is the D1 efficient at what it does?


& Ease of Use

Here I was comparing the Audioengine D1 with the Objective 2, this time pairing it with a DAC Magic 100.

I would say the D1 is very efficient given its ability to power any headphones I’ve thrown at it.

Do steer clear of trying to use it with anything over 300 Ohms, but I found it to power an HD600 and 650 with relative ease.

In actuality,

there will be very few scenarios in which you’re going to even have a very high impedance (Over 300 Ohm) headphone at your disposal, as most people simply won’t ever need one (nor will they want one given how difficult some are to drive).

For Gaming, this unit is also very efficient.

I turned the dial up all the way on Fallout 4 but found that it wasn’t necessary.

In gunfights, you’ll notice it’s plenty loud enough and even too loud in some cases.

What was stunning to me however was that even at ear-piercing volumes, the sound was still clean as a whistle.

Even so,

I like to keep the volume of the D1 set at around 75% or thereabouts. I find that it’s plenty.

It’s super easy to set up too.

For your PC, just plug that bad boy in via USB. No drivers. No hassle. No headache. It’s really that simple.

My PC recognized it immediately, and yours will too.

For PC:

  1. Control Panel > Hardware & Sound
  2. Sound > Right Click the Device
  3. Set as Default Device

You’re done! For Gaming?

Console Setup

For PS4

Note: The PS4 Slim does not have Optical capability.

  • The PS4 receives an optical cable in the rear.
  • The other end of the optical cable plugs into the back of the D1.
  • Use a USB cable from the back of the D1 into the front of the PS4 or Xbox One. I’m not familiar with the SexBox because I don’t have one, but there are USB inputs on it so don’t fret!
  • Plug your headphones in.
  • Go to Settings > Sound & Screen on your PS4.
  • Go to Audio Output Settings.
  • Click Primary Output Port
  • Change it to “Digital Out”
  • The Input format should be Linear PCM.
  • Go back to Settings > Devices > Audio Devices.
  • The Output Device should be the name of your DAC, i.e Audioengine D1.

Note: With the DAC Magic 100 I had no issues. With the D1 I ended up having to change the output device from “Audioengine D1” to “TV/Amplifier.” No big deal. Your mileage may vary.

Switching it to TV/Amplifier allowed the sound to come through the headphones. I’m not sure why it was being difficult, or why the sound wouldn’t come through even though the settings were right. If you have any insight into this, let me know!

The most important part is…


Audioengine D1

We kind of discussed it in some of the other sections, but the sound of this beast is truly special given it’s so inexpensive.

I did a comparison of the D1 and Objective 2 and came to some interesting conclusions. Let’s get into some of them!

Keep checking back for future updates/comparisons with different headphones and various other Amp/DACs!

  • Headphones Used: Sennheiser HD600
  • Amp/DACs used: Audioengine D1, JDS Labs Objective 2 paired with a Cambridge Audio DAC Magic 100
  • Source: Spotify
  • Sample Rate: 96kHz

Fickle Friends – Paris

I noticed that out of the Objective 2, vocals seemed to have more presence, with the Soundstage opening up a bit more.

The D1 sounded a bit less detailed by contrast but still sounded very good.

Caroline Pennell – Drive Me Home

Seems as though the O2 and DAC Magic brought out the little details a bit more.

The D1 was slightly essier and more metallic sounding, but the difference was very subtle.

Golden Vessel – Hesitate

The D1 seemed more detailed and articulate than the O2.

Xavier Omar – Blind Man

Both of these Amps had fantastic separation of the voices and instruments.

Both sounded extremely clear and gave room for the track to express itself.

Flor – Unsaid

The O2 seemed busier, with the chorus coming across a tad jumbled.

The D1 handled the chorus a lot better. It didn’t seem to get out of control and was less sterile overall.

I would say that the overall sound of the D1 provides a bit more warmth, while the O2 is definitely more sterile and clean if you will.

For Gaming, I could discern this quite a bit easier.

The D1 just seemed more creamy in comparison to the O2.

However, it’s still immensely detailed, so you may actually enjoy it more.

I can’t say I really preferred one over the other.

I think both were fantastic, and the comparison takes nothing away from either.

Just know that the D1 is going to excite you regardless.

It provides plenty of volume and clarity, with a touch of warmth for some added pleasure.

What’s the final grade?

You already know what it is pimpin’…

Final Grade

There’s no reason why the Audioengine D1 deserves anything less than an A+ my friend.

It combines everything you need into a ridiculously small and nonintrusive package.

Build Quality, Ergonomics, Features, Sound, Ease of Use, and Versatility are all top-notch, and for less than $200 it’s a great purchase.

The problem is that since this update, there are more versatile options for around the same price or less.

My go-to Amp/DACs in the entry-level range are the ATOM , K11, or K5 Pro.

FiiO K5 Pro Review

The original K5 Pro saw an upgrade in the K5 Pro ESS, and now the K7 and K11 are available if you are interested. The K11 is cheaper and does most of what the K7/K5 Pro does, and is arguably more intuitive and has more features.

Any of these is going to be a better purchase than the D1. 

The K5 Pro is capable of up to 768kHz and native DSD, but that may or may not matter to you.

Whereas the D1 only has analog outputs and an optical input, the K5 Pro provides those but also adds Coaxial input and Analog inputs.

It also has low/medium/high gain and more power than the D1.
