Douk Audio U2 PRO XMOS XU208 Digital Interface, USB to TOSLINK Coaxial/Optical/HDMI IIS Audio Adapter, for DAC/Preamp/Amplifier, Support PCM & DSD256

Hasta ahora a cumplido con mis expectativas muy fácil de usar, tardo un poco en llegar pero nada fuera de lo normal, lo recomiendo

思った以上に音質が悪いと感じたので、他の製品にした。

Very nice product and affordable. However, if somebody is looking for best quality, he should use the SPDI coaxial digital cable and not fiber optic, a mistake many people do. I am using Coaxial good quality cable and I am very happy with it.

In my never-ending journey for better sounding music in my system I bought this little box to put between a ROON Nucleus music server and an Audio GD R8 MK2 DAC. The dac has an i2s input which is said to have better sound than its usb input. The Nucleus, like many servers, is limited to usb output and doesn't have an i2s output. The sound through the usb input of the A-GD is excellent, but I wanted to see if the i2s offered anything better. For the relatively little cost of this Douk Audio U2 PRO XMOS XU208 Digital Interface DDC it was worth the price of admission for me. It proved well worth the cost.. It improved the soundstage, both in depth and width and in the exact placement of the musicians within that soundstage. To the audiophile's consternation, the i2s pin configurations differ from one company to another. The A-GD fortunately uses the PS Audio configuration which is what this Douk Audio U2 PRO XMOS XU208 Digital Interface also uses, but please refer to your equipment manuals to check for compatibility. Many DAC manufactures have adopted the PS Audio pi2s pin configuration as their standard, but not all. I had purchased another chinese-made DDC from Tenaelay on EBay which flipped the + and - output which put my speakers out of phase and caused a muddling of the soundstage- precisely the opposite of this Douk box. As with everything in the audiophile world, YMMV. But if you are looking for a little extra from a DAC that has i2s input this is well worth the money IMHO.

Good unit but do not like the USB input on the front. Should have been at the back. Front connection provides no options for cable management.
