    Audioengine D1 reviews

    D1 24-Bit Digital to Analog Converter is rated 4.7 out of 5 by 35.
    Rated 4 out of 5 by from Pretty Awesome First time I've used a DAC and the buzz around the internet was this little thing from Audioengine. It really sounds great and the design is so simple and functional. It super loud if you have headphones with low impedance. I used it with Audiotechnica ATH-50S and they sound excellent, very clear and very hard on the bass. But than, I popped in my Beyerdynamic DT 990 (600 Ohms version) and it barely made a dent. So I was a little disappointed there, but than again it takes another kind of beast to run the 990's. So I would definitely recommend it if you're looking for great sound for a very reasonable price. It's almost cheap considering the quality and what it could do.

    Rated 5 out of 5 by from Little audioengine that could What can I say? An great balance between sound quality and value. In fact, I wouldn't say that there is any compromise in sound quality at all. In comparison to my other DAC/headphone amp costing about 5x of this box, there are numerous recordings where I enjoy the sound signature of this little amp over my other amp. When paired up with my headphones it presents a rather warm presence with emphasized lower mids but without any compromise in bass and well extended smooth highs. It has no trouble driving low impedance (32ohms) headphones with plenty overhead. Given the value it's a no-brainer for anyone serious about best music experience without shelling out for an expensive setup.

    Rated 5 out of 5 by from Excellent DAC I started working in professional audio 40 years ago. Digital was non-existent. Later digital circuits were so slow that they could barely handle audio. It was in this environment that CD's came into existence with their 44.1Khz sampling rate. Not really sufficient, its still with us today.Then came MP3's. Dreadful! I asked why we were going backward technologically.Now more and more music is available for download in FLAC and other lossless formats and at high bit rates. Great for audiophiles.The question is how to play these files. Your computer sound card can play (usually) up to 96Khz, but with noise and hum from the computer and less than optimal analog output circuits.Enter the DAC. It takes digital output from the computer and converts is to analog. They range in price from under $200 to several thousand.I decided that I was not going to spend big bucks, at least until I could play with one. I chose the D1, not just because of the price, but because it got good reviews and the company that makes it seems to produce innovative products.The device arrived and I connected it to my MacBook Pro and was listening to music in literally moments - its that simple.The D1 has both USB and optical inputs. With the Mac it is necessary to use optical for high bit rates (>96Khz), at least that's been my result. I ordered a 3.5mm TOSLINK adapter and optical cable with my unit. You need the adapter with the Mac because the optical output is recessed into the headphone jack.Audioengine suggests a 40-50 hour break-in time for optimal results. Some have questioned why a solid state device needs a break-in. My digital gurus opine that this time is used to create error correction tables in the DAC. It is simpler to have the device do this than it is to attempt to use high precision components and add greatly to the cost. This is not a bad thing and many devices are designed this way. Remember no matter what a DAC costs, it uses sampling and errors will always exist to some degree.The next requirement to use a DAC is software that plays your music files. There are a lot on the market. You will need something besides i-Tunes, unless you are only playing MP3's since it does not play FLAC's. I have tried three players costing $10 to over $200 and one that was free. Currently using Fidelia. It seems the best for high bitrates, but crashes sometimes. Anyway, you will need some software to go with the box.I am now close to 50 hours and can make some informed comments about the D1:1. It sounded OK right out of the box, but after the break-in the sound is great. I've been playing a 24bit 176Khz version of the Rolling Stones Aftermath (US) album. Unbelievable.2. I don't need any equalization - the sound is that good.3. Hardware set-up in quick and easy. Fine tuning your software is more of a challenge, but that's not the D1's fault.4. Unit is powered through its USB port. I'm using an external power supply. This reduced hum and noise that were coming from the Mac's port. In any case, if you're using optical connections, you can save the USB port for something else.5. Best results will be acheived with high quality music files. I rip my CD's to FLACs, but that doesn't change the quality of the recordings. There's a lot of mediocre stuff on CD's and that can't be helped. With a good DAC you will get the best possible result. Direct downloads of high bitrate and bit depth files are a must.6. The unit is very small and well built. It has both line level and headphone outputs. I use the line out to connect to my sound system. The headphone jack mutes the line out when you want to use phones. The volume comtrol works on both outputs.7. Output level is quite good. It works best with lower impedence headphones. I have a vintage pair of Sennheiser HD-424's that are 1750 ohms. The unit cannot drive these well. If you need to use this type of phone get an external amplifier. High impedence phones are rare these days anyway.8. Line level ouputs use very high quality gold plated RCA jacks.9. Signal to noise ratio and dynamic range seem excellent.10. Music has a clarity and depth that I have not heard from my system before. I have a pretty good system inluding B&W studio monitors.11. Small size means that I can take it on the road with me.There are all sorts of comments on the net about DAC's. Some prefer a certain chipset over another, others talk about color and depth of sound from one unit over another. There are discussions about dithering. There is even a high priced unit that uses tubes for its analog output. The bottom line is that, if you've never used a DAC before, start with this one. You can always spend big bucks later (you'll end up upgrading your whole system).

    Rated 5 out of 5 by from Wonderful little DAC/headphone amp I use this amp to power headphones connected to an airplay device. I use the optical connection for ultimate quality. At fist I was concerned if it could adequately drive my 300 ohm Sennheizer HD600 headphones because it is just USB powered. But when I got it, It became clear that I had nothing to worry about! Wonderful, Clean, accurate sound. Excellent for both Classical music and hot Jazz. It can also serve as a preamp, so you could connect powered speakers, or a power amp and full size speakers. Although it works well usb powered from my Mac Mini, I advise getting the AC adapter so you are not draining usb power from other usb devices. Well packaged, come with a carry pouch, good fit and Finnish, responsive customer support. Simply Excellent at any price, fantastic at this price!

    Rated 5 out of 5 by from Ive transformed my notebook in a HiFi!! If you love music in it best audio quality and sometimes you really need to hear a good CD while you are working at the office, but you are far away from your HiFi system, AUDIOENGINE D1 (or D2) is for you. Paired with any good headphones, you can transform your notebook or any computer into a HiFi CD player, bypassing the usually poor quality sound cards that come embedded in the computers. Just plug, play and enjoy!! That was a great advice that I got from the folks at B&H in my last visit to the NYC store. Best Regards, Alfredo Novoa Santiago CHILE South America

    Rated 3 out of 5 by from Superb Sound and one aggravating quality issue Sound Quality is not lacking for anything.Sound is significantly better than my on-board HD audio. When paired with my Sony MDR-V6s, I don't feel the need to use any of the D1's sound enhancements. It delivers clean clear accurate sound. D1 is great for listening to orchestral music. I use the D1 with Windows 10 and Finale and Mixcraft. I only use it with headphones and like that it can also be used with speakers. I got great results with a USB 2.0 connection, meaning no noise. I got some static noise with a USB 3.0 connection on my laptop using the supplied USB cable. The D1 seems quite well made with one exception. The USB connector on the back of the D1 is flimsy. That's not to say that the connector itself is loose. It's just that very few cables stay firmly connected. With the provided USB cable there's plenty of side to side wiggle. When the D1 is moved that cable can easily slip just far enough back for the sound to switch back to on-board audio (while the USB cable is still somewhat connected to D1). I tried several inexpensive USB cables and got the same result. As a test, I connected the D1's provided USB cable to my HP printer and it wouldn't budge. It had a tight snug fit and took a bit of effort to disconnect it. To make a long story short, I ended up having to buy a 0.5 meter Wireworld Chroma cable and that seems to fit much better. It also got rid of the static on the USB 3.0 connection. So, if you plan to connect the D1 to some speakers and not move it around much then, I can highly recommend it. If you need a mobile DAC (plan to carry it in a laptop bag), then I recommend either buying a better than average USB cable or simply getting another DAC. B&H Customer Service was fantastic and helped me with this issue. I will continue to buy from B&H.

    Rated 5 out of 5 by from Great device, even better price! I am by no means an audiophile but have always enjoyed music. Some how during the digital translation I lost the proper listening equipment. Once I ripped all of my CDs into flac the stereo and CD player got put away. It took me a few years to discover why I wasn't enjoying my music listening experience anymore. I was listening via poor sounds cards, crummy PC speakers and mp3s on iPods. The Audioengine D1 has freed my digital music collection and taken it to the next level. Recommend this device if you are trying to get higher quality audio from your PC. Be sure to also check out Audioengine's speakers.

    Rated 5 out of 5 by from Super easy super sound I am moving my 400+ classical CDs to disk for easier access without shuffling the little silver saucers. The D1 gave me immediate plug and play access to my WAV files on disk thru USB in and RCA out to my Denon HiFi equipment. The sound is, as far as my ears can tell, identical to the original CDs. That ranges from a large library of opera to the most delicate piano sonatas. I am delighted to eliminate the CD media. The D1 does the job perfectly with absolutely minimum fuss.
