Excerpt: Sound quality when tweeked to your accoustical area is just out of this world. I really do not need this much sound for the Karaoke and Keyboard playing I use it for. But knowledge of the weapon I have to cater to any occasion, is power. I have never opened up any more than half the volume and the crisp sound this amp produces is so life like. I have hooked up a portable DVD player (for Karaoke singing), Mics and a keyboard to this baby and it sounds out of this world!
