Tobian Soundsystems MA 100 Push Pull Mono Tube Amplifier


“Just imagine that you can have it all: single ended magic and lustre plus the power, structure and control of a push-pull amp. I build them in different versions, all tailored to your speakers. With their genuine 80 tube watts, they give every speaker such a sonic kick that you will be completely held by the music. Power, finesse, superb detail and unlimited dynamics are happily mated. Maybe one could compare these amps with the Sistine Chapel before and after their renovation… - Günter Tobian/Tobian Soundsystems
