Love the HD800S, hate the Leafs. I think the 800S is a fantastic sound signature. I am a modest basshead who still appreciates a well done, balanced signature and the 800S is really working for me with both SS and tubes. I do slightly boost the lower bass (I do this for all open back headphones mind you) and I am extremely satisfied with the 800S. I listen to a great deal of EDM, electronica, prog rock, jazz, Nu-Jazz and the 800S is working it for me.
