Optical cable. Optical to SPDIF
Belle finition pour ce câble optique bénéficiant d'un prix très concurrentiel.
Hifime SPDIF Optical DAC (ES9018K2M)
Quatrième DAC acheté chez HIFImeDIY (ES9023 synchrone, ES9023 asynchrone, ES9018K2M asynchrone 384kHz/32bit et ce ES9018k2M optique). Après plusieurs jours d’écoutes, la comparaison se fait entre le modèle USB ES9018K2M et cette version optique. Les 2 DAC ont des sources différentes. Il donc est possible que le résultat soit aussi attribuable à celles-ci (DAC-USB/PC-GNUdebian & DAC-Opt/Box-AndroidTV). Dans les 2 cas, la sortie est la même : ampli tripath et enceintes Dynaudio Acoustics. Les fichiers audio, servant de test, sont les mêmes. Le son produit par ce dernier système est plus dynamique. La séparation stéréo semble également plus marquée. L’autre, procure un son que l’on pourrait qualifier de plus homogène. Sur de grands ensembles les instruments se détachent moins les uns des autres, mais l’ambiance générale (salle, réverbération, etc .) semble mieux retranscrite. A l’écoute de ces deux systèmes, il est difficile de dire lequel est le meilleur. Tous deux sont excellents.
I'll start with the frustration. My unit arrived the day Hifime announced a 9038-based model. I know the 9038 won't be $159, but I would definitely have ordered the 9038 instead. The 9018 is a definite jump from my Hifime 9023: better imaging, bass, and detail. A 5 volt battery extender adds to the difference. I mostly listen through speakers.The UDA 18 works seamlessly with Linux and there's enough gain to overcome Linux not being loud enough.There's plenty of detail even at low volume. Transients are really good. The highs can be slightly harsh at very loud volume, butthe issue goes away with the handful of 24/192 remasters I have. For portable use, I use it with a micro USB converter, an android tablet(my Samsung can power the DAC w/out the battery btw), and a pair of 1More Triple Driver iems. I'd been happy with a Fiio X3 Gen 2, but the UDA18 is the difference between a really good upright and a grand piano.

(edited down because of the 1000 characters limit) Purchased this for inputting optical SPDIF to a Linux PC in a test setup because it mentioned needing no drivers. Indeed it's a USB Audio Class (UAC); even the volume knob is a standard USB HID. Basic operation is quite fine. I don't have the equipment to perform an in-depth technical analysis (jitter, noise level, etc.) so I'll only mention a couple of things I noticed: - SPDIF only supports up to 48kHz; the advertised 96kHz are only for the DAC - There's some quiet, but noticeable pink noise on the analog output. - Rather basic mixer controls; mute functionality (SPDIF, line out, headphone) would have been nice - When changing sample rates first few samples are lost Not studio class equipment but good enough for my purpose. I've had trouble at first will full-duplex mode but that was caused by a buggy USB hub. (Merged two reviews)UPDATE: It seems SPDIF output works with 96kHz sample rate when selecting the "analog" output device on the PC (which outputs to both analog and SPDIF output). Only the SPDIF input is limited to 48kHz.

HiFime UAE23HD USB DAC (ES9018K2M+SA9023)
Works like a charm, plug and play on both Windows 10 PC & Android 7 Smartphone. Sound quality is great, more airness, better soundstage, deeper bass, better clarity. Not day & night difference compared to the pc headphone out, but you can hear the difference, specially with a little bit hard to drive over-the-ear headphones. On the smartphone, the difference is HUGE in both volume & sound quality. Amplification-wise, the volume is like 25-30% louder than my PC headphone out and 40-50% louder than my smartphone (Xiaomi Mi 5). I don't know if it's enought for high impedance headphones, but for a wide variety of IEM's and my ATH-M50x headphones they deliver more than enought power. Huge improvement on the bass and soundstage of the M50x, now they sound as good as they're supposed to!

I found that the sound improved by a huge amount using ASIO drivers, with Windows 10.

HiFime TYPE C USB DAC (ES9018K2M+SA9023)
I am using one of these on a Google Pixel XL running Android 8.0. Everything works perfectly with the integrated system applications, and as expected exclusive mode USB Audio applications work perfectly as well. Literally just plug and play. Highly recommended accessory for those who miss a headphone jack, or those like me who are not satisfied with the onboard audio chipset.

HiFime UAE23HD USB DAC (ES9018K2M+SA9023)
This DAC works well. Very good sound for the reasonable price. My old laptop's dac and headphones amp were so bad, and this is a good substitute.
HiFimeDIY UAE23 USB DAC (ESS Sabre ES9023+Savitech SA9023)
Absolutely amazing product! I run it with the USB Isolator + Objective2 amp + Beyerdynamic DT-770 Pro (32 Ohm) headphones. On its own, it's just mind blowing how much better music sounds compared to an ordinary headphone output from the integrated card in my laptop... But coupled with the USB Isolator, it takes the sound to a whole new level! Playing a super high definition FLAC file (192/24), I realise that the only thing limiting the sound are the headphones. The Isolator + DAC produce a crystal clear, bit-perfect sound, no distortion whatsoever. Basically, with the Isolator/DAC combo, a high quality needle drop FLAC will sound just as good off your computer as if it were being played from the vinyl itself, with the only limitation being the quality of the speakers/headphones you're using to listen to it... MOST DEFINITELY RECOMMENDED for audiophile sound at a fraction of the price!
Hifime Android DAC (ES9018K2M+SA9023)
This dac is amazing for the price. Gets close to the dac in the ifi iDSD and the Mojo. You probably cant get a dac better than this for under 200. Also its small size makes it perfect for using it with your phone. The power coming out of it is enough to drive the LCD-X's and iSine 10's without any added amp, making my portable setup super compact.
Hifime High-Speed USB Isolator
I bought the full speed isolator which works perfectly when just playing back music but is too slow for multi track recording. I decided to buy this high speed isolator with a much higher transfer rate but it did not work at all with M Audio Fast Track Pro on a widows 10 computer. Windows flagged up a warning message:USB device not recognised. The last USB device connected to this computer malfunctioned and windows does not recognise it. They asked me to send the unit back and they would send me a new unit - that was six weeks ago and they have stopped replying to my emails. So they have £70 of my money and I have nothing. HIFIME REPLY: We are VERY sorry that you didn't get any reply in time. We have refunded your payment in full now. (duplicate reviews merged).

Great product, great value of money and the BEST customer service you will ever have! Highly recommended!
Hifime High-Speed USB Isolator
Noise through my sensitive headphones is gone. Before I could hear mouse and network, now it's dead silent. Not to mention an increase in overall detail. A definitely must have!

HiFimeDIY UAE23 USB DAC (ESS Sabre ES9023+Savitech SA9023)
I bought mine a few years ago. Used it on a Macbook Air and always worked great. Today I tried it on a new (2017) Amazon Kindle HD 8" (with a USB - mini-USB adapter) and it the connection is perfect! Great sound and the tablet volume control works.

I use my medium range ASUS laptop with jriver media center with high resolution flac files , I bought this device for sound upgrade but unfortunately it's just an amplifier , no quality upgrade . if you are looking for headphones amplifier buy it , but if you think it will make your music sound better don't .
