I don't think I will ever be in a mine is more powerful than yours situation. I just want to plug in a set of HP's and know the amp is doing great. I find I don't like listening loud anyway. I have my HD 700 on high gain one third volume.
You may want to try using low gain at 1/2 to 2/3 volume instead. Common head fi wisdom says it's better to use the upper range of the volume pot for dynamics and volume tracking than to use the lower range on high gain.
