Understand Judge. Can you tell me this- with the new damper (in the tested rev range), are the harmonics issues pretty much resolved with the dual mode or is still alot of room for improvement? I'm trying to get a quantitative feel for how much better the dual mode is / is it worth the effort?? Thanks..
