I have been using the SMS-1 for a couple of weeks now. It has tightened up my bass pretty dramatically, however seemingly at the expense of some of the "fullness" and depth of the soundfield that I had been experiencing prior. Perhaps some of the tweeking necessary in my room to get the bass right sacrifices some extension in other frequencies that I had enjoyed in the past, however with boomier and somewhat more bloat to the bass. Has anyone else experienced similar results? If so, any suggestions? Perhaps its just a question of tweeking more and playing around until I can get a more satisfying combination.
