Review: Airport Express, FiiO, and high-end Audio System - Impressions - I have used Airport Express audio as an input to my audio system occasionally for several years, but I never gave it a serious evaluation for quality, other than noting it seemed "very good". For serious listening, we always tossed in a CD. Arrival of an iPad (with Airplay) in the living room, where the audio system resides, caused me to take a closer look at the potential for good audio with digital input from the Airport Express. I have a large iTunes collection, but never played much of it through Airport into the big audio system. My questions were: How good is Airport Express audio output when mated to my own above-average audio system (~$3000 speakers, $1000 two-channel stereo amp, high-quality cables, excellent CD player, large listening room)? Does using a DAC such as this FiiO improve the audio output from Airport to the above system? The answer I arrived at in my testing is that the Airport Express (using the older rectangular N model for this test) delivers excellent audio output from its integrated DAC, and using the FiiO D3 as an optical DAC between the Airport and audio amplifier does not noticeably improve or worsen the results. Every system will be different; there are huge variables in equipment interfaces, listener taste, and perception of final audio output. My system is very accurate and "neutral". My main test was playing a classic audiophile evaluation CD (Herbie Hancock, "River - The Joni Letters" - a great album, BTW) directly from a high-end CD player into the amplifier, and playing the same audio from a 320kbps mp3 rip of the CD through iTunes to the Airport Express, then either directly from the Airport to the amplifier, or through the FiiO to the amplifier. With this setup, I did blind A/B testing, shifting the amp input back and forth from the CD input to the Airport input. Neither I nor others could tell the difference, or call one source better than the other in audio characteristics. Both sounded great. The audio direct from the Airport seemed to have minutely less definition than the optical out from Airport to FiiO to amp -- but it was so small as to be a questionable perception. No one could reliably distinguish the CD to amp versus the Airport to amp, switching back and forth while playing the same album. I also ran several other CDs, including opera, vocals, classical, and rock. Results were much the same. Ears vary in accuracy; mine are better than average; I am sensitive to distortion and definition - but I make no claim to "audiophile golden ears". Different equipment combinations will offer different results. A "cheaper" or less accurate system may actual display more difference in the perceived quality between the Airport audio direct, and Airport via FiiO DAC audio. My end result: I left the FiiO in the system, running the optical from Airport to FiiO, and audio output from the FiiO to the amp. If the FiiO dies, I will toss it and just plug the audio cable into the Airport - and be satisfied. Of course, most of the mp3 files in my iTunes collection are of lower quality than the "highest quality" mp3 files I used in this test. However, it is clear that on my system and with my ears, a very good mp3 rip (320kbps, Apple lossless, or a FLAC rip) played via iTunes and Airport Express is NOT distinguishable to me from the CD player input. BTW, I also test the same CD, in a FLAC rip, via VLC, running through Airfoil to the Airport Express. Same excellent results. Conclusion: If you using Airport Express to drive a good audio amp, using the FiiO D3 as a DAC between the Airport and amp is unlikely to improve or worsen the final audio output. For less than 30 bucks, you too can spend an evening figuring this out.... Addendum, May 2017. After several years of frequent use, this is still working great. This gets an A+ from me, and I changed the rating to five stars.
Review: Optical to stereo - This is a very good device, as long as you understand what it does. It is a digital to analog (stereo) audio converter. It is not capable of decoding surround sound. No 5.1/7.1/Dolby/DTS signal, only 2-channel stereo. YOU CANNOT USE THIS TO PLAY DVDS ON AN XBOX. I bought it primarily to play my Xbox 360 slim via a computer monitor that supports no sound, so I have to use a separate audio cable in addition to the HDMI. Unfortunately Microsoft crippled the RCA cable so that it blocks the HDMI connector, so I can't get both audio and video in my setup. One solution is this FiiO box, which converts optical audio into plain RCA. In order to connect a headphone, you still need a cable that is male RCA on one end, and female headphone jack on the other. Such a cable is easy to get anywhere. You also need an optical toslink (fiber optic) cable, which is included in the product. Here's how to use this device with the Xbox 360 slim: - In the Xbox, go to Settings / System / Console Settings / Audio / Digital Output, choose Digital Stereo. - Remove the protective plastic caps from both ends of the fiber optics cable. Plug one end to the Xbox, the other one to the FiiO. - Flip the FiiO switch down (optical mode), connect the power adapter and the headphone. You'll be able to play games, but not DVDs. The problem is that the FiiO box is unable to deal with surround audio, and all you'll get is loud noise. I never play DVDs on my Xbox, so I can live with it, but make sure you understand this limitation before you buy. If all you get is noise while playing games, you haven't set up the Xbox correctly, you need to switch it to Digital Stereo, instead of Dolby. Of course the FiiO D3 also works with the Playstation 3, although you don't necessarily need it, because the Sony RCA cable works just fine. Here's how to configure the PS3 for the FiiO D3: - Settings / Sound Settings / Audio Output Settings / Optical Digital. - Make sure to uncheck Dolby, DTS and everything that is not 2 Ch. Unlike the Xbox, the PS3 can play DVDs and Blu-ray very well via the FiiO D3. You'll get correct audio, as long as your console is configured as I suggested above. If you plan to use other devices, such as Blu-ray player, etc., make sure you can output pure 2-channel stereo signal for the FiiO. No stereo surround, no 5.1 surround, no Dolby, no DTS. Otherwise you'll just get random noise. You might draw the conclusion that the FiiO doesn't work, when in fact it is just a limitation. Sound quality is great for gaming. I haven't used the FiiO to listen to music. If you're serious about movies, get a home theater. But if you want to play console games via a computer monitor and stereo headphones or speakers, this is a relatively inexpensive solution that works well. It is pretty small and seems to be very well made. The power adapter is modern and doesn't get hot. There's no on/off switch or volume control on the device.

## Questions & Answers

**Q: Does it come with a power supply?**
A: Purchase made in May, 2021... mine did not come with a power supply though a mini usb seems to be all that is required. I have not tested yet.

**Q: Is the output of the Fiio D3 sufficient to drive the Sennheiser wireless Model 120.**
A: Yes,I am using mine with the Sennheiser wireless. Works great.

**Q: Is this any good for a ps4?**
A: Yes, I currently use it in my ps4. The sound quality comes out very good. Only issue is it takes up 1 of the usb ports (that's how it gets powered). But totally worth the money.

**Q: Will this work connecting a Bluray Player with digital out to a receiver with analog in?**
A: Most BluRay and DVD players have the ability to downmix the audio stream within the player to Stereo.   As long as you do this, it should work fine.  If you are connected to a receiver that doesn't have digital inputs, then I suspect it also doesn't support surround sound, so the downmix will work perfectly.

### ⭐⭐⭐⭐ Been working for over a year
*by R***1 on June 9, 2013*

I have to say this is a neat little device. Unfortunately, my Vizio tv has a bad audio skip in it. I didn't realize it was the TV til later on but I knew even with the problem I wasn't gonna send it back. Shipping would have been a fortune so I decided to try and bypass the audio by using a DAC (Digital audio converter). I found this little device and tried it...works like a charm. I use a Micca media player and a philips dvd player and both have optical and coaxial digital outputs so I plugged either into my much better PC speakers into this device and I get 100x better sound than the tv. To solve the "skip" issue I have with the Vizio tv playing in unison with my PC speakers was pretty simple. I just turn the volume on my TV down or off and let the PC speakers do all the work. Works perfect. This device doesn't get hot or anything. There is one issue however that I must bring up. The coaxial digital isn't grounded correctly unfortunately. It "hums" when I go with it. I can rotate the cable while it's plugged into this unit and you can hear it through the speakers. I tried the fiber option (cheap cable came with this unit) and no problems. So I've been using that ever since. This device also needs to be a tad cheaper. $30 is a bit too pricey for what you get. To sum it up, If I lost this device or it broke...I'd buy another one.
