It sounds every bit as good as the Coax out from my Squeezebox Touch. There are no clicks or drop outs. The only other converter I have used is one made by Opera Consonance. It only converted to 24/96. The U18 works equally as well with the D18 as it does with the D100 II. I am using the AES/EBU to connect the U18 to the DACs. I am pleased with the performance for the money. Over the next while I will try the different connections (coax and optical) and test if using the seperate power supply makes a significant difference.
