Hifime High-Speed USB Isolator
Unfortunately, it does not support DSD512. If a new model is released, please support it. I am using SU-8 of S.M.S.L.
HiFime TYPE C USB DAC (ES9018K2M+SA9023)
Love the sound and form factor of this DAC! Unfortunately I've had problems with the USB-C plug on my first unit out of the box. The connector was lose and would easily dissconnect with the smallest movement. The replacement unit I quickly received (great service even over here in Europe from hifimediy!) has the same problems after a few months. I wouldn't recommend it for mobile use. I ended up using mine only at home on my phone where it still get's moved around more than on a laptop. Apparently that is already too much for the built quality of the connector. As I said, otherwise great unit which really makes me want to try the bigger DACs from hifime, like the UDA38Pro.

Works as promised. Connected to an USB hub which sends MIDI to hardware synths. Zero problems.

HiFimeDIY UAE23 USB DAC (ESS Sabre ES9023+Savitech SA9023)
Instead of doing a subjective testing, I decided to do a proper test with RightMark Audio Analyzer (it is free and you can do it without any having to buy any fancy hardware). The frequence response (multitone) for the Sabre DAC from range from +0.01 to -0.07 dB, Build-in audio range from +3.3 to -10.99 db (Closer to 0 dB is better. Every +3db = double in volume and -3db = half in volumne) The frequence response (swept sine) for the Sabre DAC from range from +0.0 to -0.0 dB, Build-in audio range from +6.4 to -8.0 db. I wish I could put in an image of how bad the build in soundcard fluctuate. It is all over the place with no smooth curves or flat spots. Noise level, stereo crosstalk, ect. are drastically better. In summary: The output is as close to perfect as one can get. No matter what you connect to this DAC, this DAC will make a big difference in improving the sound quality. For this price I would not buy anything else than one of hifime's DACs.
Hifime UDA38Pro DAC (ES9038Pro + SA9227)
I couldn't sleep after ordering UDA38pro and seeing a bad review of it. But it turned out that the ES9038pro was real. The wide stage and natural sound made me like the sound of the ES9038pro. There are a litte problems. The noise is caused by the electromagnetic wave and it is a little bit larger for mobile devices. But more than offset this all is the special sound of the ES9038pro. I bought UDA38pro very well.

Hifime UDA38Pro DAC (ES9038Pro + SA9227)
During break-in of my freshly arrived UDA38Pro, I started listening with just a stock power supply and stock USB-cable. I found the sound a little too noisy for audiophile use. Disconnecting the stock power supply, running solely on USB power, eliminated most of the noise, but in order to let this DAC really show its full potential, some (limited) extra investments are needed. In effect, it appears to be more sensitive to the choice of power supply and USB cable than for instance my Focusrite Forte DAC/ADC. I now use the following accessories (listed in order of importance for boosting perceived sound quality): 1. iFi iPower 12V 1.8A power supply, 49 Euro 2. Supra USB 2.0 cable 1.0m, 37.50 Euro 3. Audioquest Jitterbug, 39 Euro Combined with my Nura headphones, this yields a big 3D soundstage with incredible amounts of detail and dynamics, wow! Also my speakers sound much better with this DAC, including a wider stereo image and tighter bass. Highly recommended!!!
Hifime High-Speed USB Isolator
My new build suffered from terrible crackling/static/clicking noises that were driving me mad. No one seemed to have an answer, and none of the advice online worked. Eventually found this device, plugged it in and the noises disappeared instantly! This proved that (in my case) the issue was some weird USB grounding problem. Huge relief now this problem in solved and totally clean audio! Highly recommended.
HiFimeDIY UAE23 USB DAC (ESS Sabre ES9023+Savitech SA9023)
I have always been fascinated with Hifime product, so I decided to take the plunge and purchase the HiFimeDIY UAE23 USB DAC (ESS Sabre ES9023+Savitech SA9023). I have the Dragonfly USB DAC by Audioquest so had something to compare with. To be honest I was very disappointed. Unfortunately the hype was build up to such an extend that the whole listening experience was very disappointing. I did a lot of A/B listening between the Dragonfly DAC and the Hifime DAC using my audiophile Sennheisser headphones. The HiFime DAC stripped the life out of the music with very deep and muffled tones, stripping the individuals guitar, bass, cymbals and muffling them all together. I really thought something was up with my settings but as soon as I would plug the Dragonfly DAC in, the music and each instrument would come back to life, adding clarity and enjoyment to the music. Very disappointed and somewhat sad as I wanted this Sabre DAC to shine. Also, the packaging and unit is cheaply made in China.
Hifime UDA38Pro DAC (ES9038Pro + SA9227)
I use these dac whit my 4000 euro amplifier from Naim. Its much better than my old expensive dac. The sound is liquid and reminds me about my old records player. This is the best dac I have listened to.

I am using 4 of these plugged into a Raspberry PI 2B (running 4 instances of SqueezeLite) to play music (through a multi-channel amp) to 3 different rooms and a pair of wireless speakers. All are individually controllable through the Logitech Media Server interface. This is a high quality yet inexpensive solution for "whole house" audio. I have used these since 2015 and plan to buy more when I add more rooms to my "whole house" audio system. Highly recommended.

Hifime UDA38Pro DAC (ES9038Pro + SA9227)
I always felt skeptical about investing in DAC, but man this little device proved me wrong, what a difference, it's a day and night difference compared to my focusrite. Worth every penny.

FINALLY something that works with my Steinberg UR824. USB noise is gone, sound is clean.

Hifime UDA38Pro DAC (ES9038Pro + SA9227)
Coming from Resonessance Labs Concero HP with the Sabre chip ES9018-2M, and also using the internal DAC of the Woo Audio WA7 2nd gen for awhile, uda38pro is definitely an upgrade coming from both. uda38pro's sound is more clear, natural, and musical. There is also more space between instruments and the details stand out more. This is what I am using to feed the WA7 and the combo sounds fantastic with HD800S. Like others said, use an external power. The signature does not change but the sound definitely get slightly enhanced and opens up a bit more. I am using a DC 12V 2A that I had sitting around. For $250 and after using it for a few months now, this is a no-brainer recommendation.
