Ok now I'm gonna go a bit hyperbole.. Doesn't happen very often. But I'm hearing things in my fave tracks that I've not heard before and the soundstage has increased an extra cm.
Moody and Rob. My dear friends of vintage, I deplore you not to try one of these QED amps for your HE6's if you can. I feel the need to tell you this and in fact I bet my own bottom that you would thank me dearly if you do. I'm sure they have the power +. But it's the smooth refinement and clarity! Yes clarity.. Cheap as chips too!
