@markmuse I think you are the first person I ever heard describe an AGD amp as "Thin". Did you give them time to settle in? Did you use a good power cord? I can't speak for the Audion, but my GV's are far from thin. Also, the tube is not fake, it is the actual output stage, pull it out and guess what, no sound. Over priced is relative, people spend 20K on 5w set amp, so price is highly subjective IMO.
