This weekend my wife and I had 3 couples over for dinner. All non-audiophiles but they know about my passion, or obsession as they call it. We were listening to a CD and after 5 minutes I stopped it, I forgot to Nespa it> They asked what the hell I was doing and I said just wait. After a 60 cycle blast I inserted the CD again and the reaction was wow! Especially the woman. They said the top end was easier on the ears, no more, and this is where it's strange, they couldn't discribe it just they now thought an edge was gone, sounded cleaner and more relaxed. One even suggested more dynamic, although they described it as seeming to go softer but louder all at the same time.
Just thought I'd share this experience, I hope this thing never burns out!!!!!!!!!!!!!!!!!!
