So far, I have mixed feelings about my Gumby. On some recordings, it sounds amazing. Percussion and horns have never sounded so good to me before. However, other recordings sound so harsh it's almost painful to listen to them. These are recordings that were fine on my old Gungnir, even good sounding on it. I have 80 hours on the unit so far, and wonder if additional time will smooth out the harshness.
