iFi uno - DAC & Headphone AMP - USB-C Input - Improve Lacklustre Audio - Streaming/Gaming/Music Modes Adjust Sound to Suit You - 32-bit/384kHz/DSD256/MQA - Windows/MAC/Smart Device/Active Speakers

I need to be able to play music from my iPhone through my home audio system. My home receiver does support Bluetooth, but I was unhappy with the experience of connecting the phone this way. I found that I had to turn the volume on the receiver WAY up in order to hear the music at an acceptable volume. I also wasn't thrilled with the overall sound quality. I'm no audiophile - this is just music streaming from Spotify, not lossless FLAC files - but I felt like it should sound better than it did.Enter the iFi Uno. This has proven to be exactly what I needed. In my case, I had to pair it with the "Apple Lightning to USB 3 Camera Adapter", which you can find here on Amazon for about $38. With these two devices, I'm able to enjoy music from my phone through my home audio system at a high level of quality. Hook the lightening adapter to the phone. Hook the Uno to the USB-A port on the adapter. You're good to go. For bonus functionality, hook a lightening charging cable to the other port in the adapter, and your phone can also recharge while it's playing your music.With the Uno device, you are bypassing the iPhone's onboard DAC in favor of the dedicated one in the UNO. I can definitely hear the difference in quality. You also get the benefit of the Uno's pre-amp, which lets you boost the volume a bit, so that you don't have to go nuts with the home receiver's volume. I'm connecting to the home receiver with the Uno's RCA connections. I am using the Uno's "power matching" feature, which seems to add a slight increase in strength to the signal, but it's very subtle. This feature may be aimed more at headphone users, but that's not what I needed the device for. The onboard equalizer seems to work fine - I can hear the difference in the 3 pre-set sound profiles - but I don't use it. I prefer to use Spotify's equalizer to adjust the sound if necessary.So for about $120 for the two devices, I have a setup now which allows me to get the most out of my streaming music and my home audio system. For me, it's been well worth the cost. The only downside is that this is a wired connection. It lacks the convenience of Bluetooth, but the improvement in sound quality and volume has been well worth the slight inconvenience for me. I hope someone finds this helpful.

This is an incredibly small and light DAC with a lot of power. Listening on this with my AKG N5005, I could hear no noise at all, so I'm very happy about its noise floor. It sounds slightly warmer than my Fiio BTR 7 with a little bit less spaciousness, but still very detailed and enjoyable. The EQs are a different story though. Of the 3 EQs, only music mode has the same low noise floor as normal mode. The other 2 gives a lot of noise - especially the game mode. The unit also seems to become incredibly sensitive to interference in game mode. It also makes a huge popping noise when switching into EQ (to game mode) after not touching the EQ button for a bit (capacitor discharging?). If you mainly use sensitive headphones I would not recommend using the EQ functions. Other than that, a solid DAC.

Sounds great, powers my hd600 pretty amazingly, and those are hard to run. As long as you're not plugging in crazy headphones, it'll power them. It processes audio pretty well. It's small, light weight, alright in build, mostly plastic. But has a metal knob, which is nice. It is really touchy with volume control though, especially on windows. Just be aware. I just have had issues with it cutting off for a second very often, may not happen to you, but still can. Just something to be aware of.

Sound is great it powers my hd 600 headphones no problem

Doesn't change the IEM sounds at all which is great way to test IEMs. Gets very loud with cheap and expensive IEMs. Very small and can connect to speakers. Love the simplicity.

The Ifi Uno is a fantastic DAC for the price, during my ownership I had purchased the Uno and enjoyed it for about 3 weeks before I encountered a issue regarding the audio (I would only get audio from one side of the headphones regardless of the pair that I used.) This was covered under the Amazon AND Ifi warranty so I was able to get them replaced. Over the time that I was able to use them AFTER my new Uno it was extremely high quality and never let me down with powering my hd58x. Unfortunately as of 3/23/24 which is 4 months after I got my warranty Uno. It has suffered the same exact error where my right side channel has failed, it only lets out audio from the right and distorted audio from the right. I will be changing to Topping DX1 on my audiophile journey

This device is for people who directly feed digital audio to home audio systems. The device converts digital to analog audio. The difference between analog and digital is night and day! Well worth the price!

Outside of the capacitors popping, I love this little fella. The LED lights around the volume knob reflect the frequency of your music which is quaint and if you ignore the EQ completely and make sure you’re happy with the filter you’ve applied (press holding the EQ button until the top LEDS flash to choose) you should be fine with this little entry level DAC amp no matter what.
