So the U2PRO from Douk Audio arrived, installed it and it works as it should. Zidoo UHD 8000 to Z10 via USB and U2PRO to Z10 via i2S.
Hi, yesterday the U2 PRO arrived, I plugged it in, installed it in Foobar2000 and everything works as I wanted. In the DAC Z-10 settings, the first position is I2S. I can recommend it if you listen from a PC.
I have the Z10 + T8 combo and I'm amazed at the performance. I've tried both USB and I2S over HDMI and my initial impression has been USB is significantly better however now I've lived with this setup for enough time for everything to be burned in and settled down I'm keen to circle back and make the comparison again. I'm using AQ Coffee USB cable and AQ HDMI cable. What are considered the best settings for I2S?
All these cable and port combinations are pointless. Digital has very high system requirements. The only rational solution is high-quality, complete processing devices – streamers. They input a digital signal, and output a Hi-End analog signal.
