I would agree, the LS7 is a wonderful pre, especially for the money, however, I have not compared them. I currently have a LS7, which was my first tube pre and I love it. It has 4 tubes, so it isn't to expensive to roll tubes, but I can say that you will want to play with different tubes to really make it sing. I am currently using Bugle Boys and I think they sound the best for my setup. It is quiet and the soundstage is excellent, but that came after rolling a couple different tubes.
