Différences audibles entre Sabre U2 & Sabre 9018
1/ Chaine HiFi :
- Même niveau de sortie.
- Différences audibles. Le Sabre 9018 sonne plus clair sur l'ensemble des registres. (le 9023 sera plus agréable pour certains auditeurs)
2/ Casque audio :
- Niveau sonore plus fort pour le 9018.
- Son plus détaillé sur les registres médium et aigu pour le 9018. Pour le grave, c'est moins flagrant.
Le Sabre 9023 est bon dans les deux cas.
Pour le casque préférez le 9018.
+ le 9018 chauffe plus (pas grave)
++ la LED du 9023 ne s'allume qu'en lecture audio , le 9018 reste allumé
I bought this some time ago when I built my pc. Unfortunately, I regret buying it. I constantly get blops and pops, sounding like its trying to correct itself from falling out of sync. I dont know if my device is defective maybe.. I also bought the Isolator, which unfortunately makes no difference at all. I am really disappointed and will not recommend this product to anyone. Hifime reply: It shouldn't behave like this, please contact us to arrange a replacement. And the isolator will not help if the problem is with the U2.
I build a fully finished professionally amp based on this module and was extreemly impressed on performance and sound quality. I have built five class d amps and this one may be the best.
The amp drove $60K Verity speakers to abolsute perfection. In fact it drove them so well the importers have asked me to make an amp for their store. They were stunned by the performance.
Thank you guys for the confirmation and the very good device at reasonable price. It is easy to use and works well with foobar2000 software. I really appreciate it.
Outstanding for the price....am overwhelmed by the quality available nowadays at this price.
Obliterates the HRT Microstreamer which sells for more...
I've received U2 Async DAC yesterday. Really great sound and I like it. I only notice a pop noise from the DAC to the speaker when i'm switching on my computer. Mine doesn't have green or blue jack connector but something between brown and black color. So I'm wondering if it is an authentic Hifimediy U2. It's led color is red.

----hifime reply:yes it is authentic. We use another connector on last batch, it has LED light built into the connector so provides better optical performance.
The improvement over my motherboard's sound was phenomenal. Music became very lively and fun, while my video games came to life. I did not expect the improvement to be so apparent because I bought this DAC while still being skeptical of their claimed improvements in sound. Worth every penny!
An excellent dac, I have purchased it as an upgrade to es9023 sabre I had before, and the difference is tremendous, especially in the music scene and separation of instruments, much Microdetail.
I use a takstar PRO80 through the headphone output and has enough power to drive a very decent volume.
the amp is ok but i don't need remote
jumpers are the better way
Very good sound, no complaints there. True high resolution and absolutely amazing. The only problem is that its hard to adjust the volume precise to your liking. It goes up and down too fast. Also my unit volume up does not work consistently, will have to press a few time before it starts working. If there is a firmware update which can fix the volume up and down sensitivity, it would be amazing. I am hopeful -:)
Very well rounded dac with even balance across all frequency and while it doesn't have the widest soundstage, which actually may be good for some songs, it has precise positioning and imaging thanks to its separation capability. With its small size (quite small unlike one might think looking at the picture), it's a great transportable DAC for notebook users. In theory you should also be able to use with smartphones if you get it usb splitter and power bank but I haven't tried it yet.
All in all, very good DAC for the price!
Очень музыкальный и стоит своих денег. Рекомендую. Asio звучит хуже асинхронного режима. Драйверы не нужны на WinXP. Спасибо создателям этого маленького по размеру, но не по звуку, DAC! Рекомендую.
Very musical and very good value for money. Recommend. Asio sounds worse asynchronous mode. No drivers are required for WinXP. Thanks to the creators of this small in size but not in sound, DAC! Recommend.
This is a great sounding DAC with a nice design and proper digital volume control.
For more info check my review at Head-Fi!
The sound quality is excellent ! The battery drain is OK,
It works great on my GALAXY S5.
The only problem I'll point out: The cable is too short and too stiff. It puts too much strain on the USB port of the phone. After a few month, the connection between the phone and the USB DAC became too loose, and I have a lot of 'USB disconnected' message on my phone.
Even the metal part at the end of the USB tip start to move inside the plastic jacket.
So be careful with it and everything will be fine.
I rarely write review; this time I felt obliged to. I wanted to buy Arcam FMJ A19 (What Hifi best amp, 2014 up to £800). Seller brought it over for comparing. I must say I am struggled to find a difference although I was hoping to have a proper Amp. finally! I politely declined to purchase, I am keeping mine definitely. I changed my caps to Jentsen superior Z caps and listening with Dali Zensor. All I could say impressive especially for the price.
