@jumia just not true.
I have heard that most speaker designs are built to deal with solid-state amplifiers. Add that buying a tube amp does not flourish with modern day speakers. Wish I could recall specifics as to why this is. Maybe someone else does.
The Legato Series was engineered in a way that they can be driven by a small or large vacuum tube or solid state amplifier and easy placement or set up in a room. Sophisticated cabinet design utilizing one piece molded curve cabinet, state of the speaker drivers, and high quality crossover components work in harmony with our Symmetrical Panoramic design crossover network to deliver a natural sound, effortless micro and macro dynamics, huge soundstage with a sense of air around the musician and instrument while maintaining music emotion.
This series was created to deliver musical expression, huge soundstage and vivid imaging on a small foot print with a more attainable price point.
