            I'm an audiophile searching for the best way to improve sound from my computer. I found a big part of the answer in this digital-to-analog converter, with its headphone amplifier. The difference in sound between this unit and plugging the phones directly into the computer is dramatic. The sound is more detailed, more musical, with more undistorted highs and lows. Strongly recommended.

                I find the sound the D1 produces with Audioengine A2s to be better than a previous amp I used, although a tad too aggressive on the ends of the spectrum. Mids seem to be a tad uneven and present a problem when trying to EQ.
                The D1 does a wonderful job on the low-end, and the A2s really respond to that. Same with the highs, very crisp sounds there.

                  I have used Audioengine's 5Plus powered speakers for several years and have been impressed except for distortion.. They had been paired with an unnamed product consisting of three Jack Ryan novel sized units, with wires everywhere and an IMac. Unfortunately, I experienced considerable distortion. The D1 replaced all three and the sound is crystal clear. No discernible distortion. I couldn't ask for more.The only thing that some users might find negative is that the system bypasses all equalization and volume controls on the computer. This is not a problem for me, but if other listeners want a boom box, they will have to provide it after the D1.A big plus is the support Audioengine provides its customers. I emailed them twice with questions regarding the use of the product. In both cases, I received a response immediately. All manufacturers should have the quality of product and customer support they do.

                  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.

                      I was listening to music a lot at my computer as I worked. Bought this after a bit of research and it has transformed the music I have been listening to for the past months - I can hear instruments and sections of music previously missed, and all through the same headphones and the same music player and files as before. Stunning! I'll never go back to basic motherboard audio output again.

                          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.

                            I'm starting to get into audiophile quality digital music and this took my mac mini to a higher level of audio for a very reasonable price. Easy to use and nothing to install. I'm getting a MacBook Pro soon and the mini will be my media computer and I'll upgrade to a higher quality DAC to use with it and the Rec/Amp and quality speakers and this Audioengine will be conneted to the macbook when it's docked at home to use with my Logitech speakers.

                              Some of my friends own much larger and more expensive DAC systems - I needed a small bus powered device that was simple and high-quality. This fit the bill perfectly and I'm very happy with my purchase. Comes with a nice carry pouch and a its made out of aluminum - a well constructed device which improved audio quality dramatically to both my headphones and monitors.

                                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.

                                    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.

                                    Comments about Audioengine D1 24-Bit Digital to Analog Converter:

                                    I have a large collection of digital music mostly FLAC files. I was interested in finding a small reasonably priced DAC to improve the playback quality of my existing library and to experiment with high bit rate downloads.

                                    I chose the Audioengine D1 because it seemed to offer the features and price I wanted. I researched a number of units - some costing thousands of dollars.

                                    I have had the unit for a little over two weeks. My impression overall is that it is an excellent product. I have contacted their technical support with questions and found their responses prompt and helpful.

                                    I'm using the unit with a Mac Book Pro. I have used both the USB and optical inputs and prefer the optical. I use both the headphone output, but mostly use the RCA jacks with my home sound system.

                                    The thing that you need to know is that good player software is necessary to use a DAC. There are several on the market. Some integrate with i-Tunes and some are stand alone. Most have free trials so you can select one that fits your needs.

                                    All DACs require a burn in period of 40-100 hours. This unit sounded good out of the box, but improved with use. Be prepared to go through this process.

                                    The sound produced by a DAC is an improvement over computer sound cards and most DACs will play higher bit rate and bit depth files than internal sound cards.

                                    I have used the Audioengine D1 with extremely high resolution music downloads and been pleased with the results. Again, pick your player software carefully.

                                    The headphone output has excellent gain with low impedence headphones (most are low impedence). I have some vintage Sennheiser HD-424s which are 1750 ohms. It cannot drive these without an additional amplifier.

                                    This DAC requires no drivers and worked the first time. It detects optical and USB inputs. Use of the optical input requires cable and an adapter. The unit has an internal relay to switch modes and this makes a clicking sound at the beginning of a playlist. Slightly annoying, but not a big deal. Once in the optical mode it stays there and the relay is not heard again.

                                    In short, it is a well made and enjoyable product. Like any other high tech device the more you understand about it the better it will serve you.

                                    The specs claim that it is capable of sampling rates up to 192Khz with its optical input. This may well be true. Newer Mac Book Pros can theoretically produce this output optically. However, in practice I can't say that you can do better than 96Khz due to limitations of the Mac Audio MIDI. This is not a criticism of the D1 as much as a caveat for those who want high sampling rates. I put this question to Audioengine support and they are not clear as to how you get a 192Khz optical output from a MAC. It may require driver software that does not exist right now.

                                    If you must have high sampling rate performance, you will need a Firewire DAC. However, there is limited repetoire available for download and there is a real debate as to its benefit. Plus, these DACs are quite expensive.

                                    In conclusion, if you want an entry level DAC with real performance, this is a fine unit. Its small, portable and well made.

                                    Comments about Audioengine D1 24-Bit Digital to Analog Converter:

                                    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).

                                    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.
