I have a Raspberry Pi B Version 2 and am able to get a HiFimeDIY Sabre U2 Asynchronous USB DAC working with it. The only mod is to prioritise USB audio over HDMI and analogue.
I also obtained the HiFimeDIY USB Isolator, but when this is installed inline, the RPi is unable to identify the DAC at boot up. This is not a show stopper, as the DAC is working fine and I am not experiencing any white noise with it. This DAC is only designed to go to 96khz, and I am satisfied with that.
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.
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.
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.
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.
