The MA1.6s is one of a range of power amplifiers that have been
designed to combine reliability and high power with sonic
excellence. Utilising an advanced switch mode power supply, the
amplifier is characterised by a very high power-to-weight ratio in
a lightweight, 2U package. The innovative technology at the
heart of the MA1.6s enables it to set new standards in terms of
sonic accuracy, impact and clarity.
