Review on Douk Audio U2 PRO XMOS XU208 Digital Interface - USB To TOSLINK/Coaxial/Optical/HDMI IIS Adapter For DAC, Preamp & Amplifier | PCM & DSD256 Support by Randy Brimmer

I just received, and installed this device in a sound chain that includes a hp laptop, to Audioquest Cinnamon USB cable to this USB to IS2 converter to Topping D90 DAC to Monoprice Liquid Platinum to HiFiMan Arya headphones. The improvement in sound quality which was already outstanding was far above any expectations I had. Many reviews may not realize that everything in your sound chain affects the final result. This device is a must have for people who have interest in getting the most from what they have!This also works very well as a USB to IS2 converter interface to feed the IS2 input on a Musician Pegasus DAC. It’s works seamlessly and their is an audible improvement in sound quality. My new sound chain is a laptop receiving Tidal HiFi to USB output, to this device, which feeds my Musician Pegasus to my Peachtree SE 220 amp, to my Magnepan LRS speakers.
