FX-Audio FX03 USB C DAC 384Khz DAC Decorder USB-C to RCA Digital to Analog Audio Converter Support DSD 256 PCM 32Bit for Set-top Box,Mobile Phone,Computer,Game Machine

Instantly recognized by my macbook. Perfect clarity from laptop to DAC to amp to headphones. Maybe this is a hot take, but if you're looking for a DAC to connect an amp to your computer, you do not need anything more than this, even at audiophile levels. This is designed to do one job and it does it perfectly. Build is great. It's tiny and unintrusive, but still looks great wherever you find a spot for it.

This is a great cheap DAC for a Raspberry Pi. I'm using this with a Raspberry Pi running the Volumio software. It sounds great.

Overall it's not bad at all! The high notes are a little too high the rest reasonable and of course on 60s and seventies tracks the bass could be better but I suppose for the big bang there has to be matter there in the first place! But I think Bluetooth aptx HD does a better job on these!Where this little phone powered usb c DAC amazed me was on its wonderfully low use off the phones battery power! With the phone screen on full time I easy got 5 hours almost continuous play of audio tracks from a full charge on my Pixel ! I used 60% of the phones power with that phone screen lit all that time!The RCA lineout did not impress me or my power mixer preamp I had to use a RCA line booster to get decent volume and was fine after that; Im not sure what voltage the RCA out is but it must only be 2 volts approx.! I'm used to CD RCA line out!I was worried that this DAC it would drain my phone battery fast - what a lovely surprise for me!

This little guy... Yes!I have had issues for years (literally) with hearing audio feedback (while on any gaming PC) I assumed from the GPU. I even tried upgrading to better and better speaker setups hoping that noise filters would provide better quality.Anyway, I CAN hear the audio difference so the conversion is there. Note that it's not louder, just... Cleaner (?).The feedback I have experienced for-EVER: completely gone once I powered this DAC on.Speaking of power, I had initially used a C by C cable and for some reason the DAC wasn't powered, but it did come with a USB by C cable which immediately illuminated the Power light.After that, plug'n'play Windows 11 immediately recognized it (all-be-it, as headphones) and I was able to use it with no further effort on my part.It doesn't take up much room, but make sure you place it where it can vent heat since it did get warm to the touch (not hot) so it doesn't get ruined.

I will be as thorough as I can regarding this DAC. I originally was using a PROZOR 13 dollar DAC that i connected to my pc through optical. Then the analog audio would pass through to a Fosi T20 tube amp. This setup was perfectly capable of running my Hifiman He-x4. However when I upgraded to the HE-560 V4 I noticed that my amp was no longer sufficient to drive these headphones. So after doing a little asking around I determined the issue was the PROZOR dac, prompting the purchase of this unit. Upon first installing the FX-03 I noticed a huge increase in volume and drive, my headphones now sounded the way they obviously were supposed to the entire time. I enjoy the minimalist look of this DAC, as well as its compact size. One issue I did have is that the USB it comes with is not very long and using other cables can lead to instability issue, however I had a compatible one that works fine and is long enough. I recommend this DAC, it offers some serious bang for the buck.

An outstanding high resolution DAC chip married to a state-of-the-art USB controller chip. All housed in a VERY tiny case fits easily in the palm of your hand. At $50, this is an amazing value. Audiophile specs on a beer budget. Buy two! :D

I wouldnt recommend it, unless you need some 1-time use thing. Doesn't seem to work anymore. I have this mounted under my desk and it never moves. But, i can unplug/replug this back in several times and it will sometimes come back a minute then the audio starts to dip out, or the interface disappears in windows.UpdateSeller reached out to me. Had me try a bunch of things to see if it worked. Nope. Defective unit. Wants me to go out of my way 45 minutes to a nearest UPS to ship back for a 40 dollar unit. No I would buy something else

So far this little DAC is delivering great sound from a laptop to a vintage Sansui receiver. Who would have thought this 37 year old Sansui could sound so good. Can't comment on longevity yet, so maybe I'll update, but for now I'm giving this 5 stars for incredible sound at a very reasonable price. Simple and effective.
