No my amp isn't tuned for R10's why would it be? I tried every tube combination I could think of from 6sn7/2c51/6414/12au7/5687 as the input tube to the 6080/6528/7802 as the output tubes. They just aren't headphones I like very much. Yes I do listen to quite a lot of rock, but I do also listen to vocal, jazz and the occasional classical. Didn't really like the R10 with any of the music I tried them with.
