I owned the Rogue and now own a Modwright and a Joule La-100 preamp. The Rogue had the biggest fullest sound of the three, but it was too big sounding to my ears. It also was on the noisy side. It has a warm sound to it tubby sounding but not overly. I think both the Modwright and the Joule preamps are a step up from it. The Modwright is the most neutral while the Joule is more lush and warm, a fuller bottom end and would sit in between the Modwright and Rogue in my opinion warmth wise. The Modwright is the most dynamic , the Joule has the most inner detail . It really depends on what preamp sound you are loking for. I have my Joule on sale here, alhough I am not sure I like the Modwright over it better.
