Yep, thanks to Jim of Hagtech for sending me the three diodes that I dumbed out on and didn't order from DigiKey. Just hooked it up about two hours ago. So far I am very impressed. I don't know how long a burn-in time it needs if any but it sounds good right off the bat. Definitely more bass and quieter backgroud. As a result, more detail but no sibilance that I was experiencing before. Would like to post a pic but haven't figured out how. More to come later. Nick
