Can you comment about the R2R 11's ability to retrive details and its soundstage comparing to the Matrix? I have the Matrix currently and just like to hear some opinions about the 2 gears. My headphones are not power hungry so power is not an issue for me. Also, thank you for bringing the pop issues to light. I have a Yggdrasil, and I used to have the optical out from my Creative X-fi to the Yggdrasil. Doing that made the Yggdrasil made a click sound constantly, every time the sample rates were changed. I couldn't stand it either so I changed to another SPDIF transport, and the clicking are gone. So the R2R 11 is not the only dac that has this problem. I don't have the R2R 11 yet but I could see how the pop sounds come about.
