In an earlier post I stated I have two Denis Had amps I enjoy a lot 45/2A3 and a Universal. What I don't get is when Dennis Had builds the next amp for someone else it is always the best one to date that he has built. Made changes etc, than on the last type of amp he built. What you have is inferior from the latest greatest build. I guess it's a good way for a person to keep buying from him to get the Holy Grail amp LOL.
