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 Jason Adams

Wow! This was a major upgrade over USB. I run this into my Pontus 2 DAC's I2s. I also tried it on a Topping DAC's I2s and it was also a major improvement. I'm using an Audioquest HDMI cable. Much more detail, sound-stage and dynamics. I can't imagine not using this. I upgraded to a $600 Denafrips Iris for i2s. It was not an upgrade! The Douk sounds better and the Iris gave me severe listening fatigue. Don't let the price fool you. This is a seriously good interface! Best audio purchase for the value ever! Thank you Douk :)
