I got the Gramma today and placed it under my Velodyne(LFM arrives tomorrow). What a difference! It actually makes me appreciate the Velodyne. I put in Attack of the Clones -Scene 3- and the explosion of Amidala's ship was tight. Before it sounded sloppy and muddled. The Gramma is an excellent purchase. I can only imagine how it will sound with the LFM. Highly recommended.
