This amp has replaced my all tube Mcintosh system. I am amazed with the details and sound stage capabilities of my Luxman sq-N10 unit with speakers and headphones. Rogers Export Monitor II speakers, Denon d7000 headphones. Using stock tubes and do not fell it worthwhile to do some tube rolling. This unit is giving me superior sound to any system I have owned over the past 50 years (audio research,mcintosh). Am I happy? Yes! 
It has been a couple years since your post so if you still have the N10 it must be special!
