I just recently upgraded from the Shuttle 6.0 to the 9.0 and notice the increased headroom when playing through my NEO 212 (I will be selling the Shuttle 6.0). I have not had the chance to play the 9.0 through the NEO 112 or the XB410, but I expect the results to the be same. Here is my question.... I am considering replacing the NEO 212 with the UBER 212 based on what I have read on TB. Is there that much noticeable of a difference? I love the size and portability of the NEO 212 as well as the sound but I have heard the UBER has a fuller bottom. What are your thoughts? Shuttle 9.0 on an Uber or on the NEO?
