Formerly imported from Italy by May Audio, when Art Dudley reviewed their Mastersound 300 B S.E. integrated amplifier
, MasterSound may be poised to re-enter the US market. Through Diapason loudspeakers, I was intrigued with the sound of the Mastersound Final Amplifier 845 monoblock, a parallel single-ended eye-catcher. Mastersound's Dueundici preamplifier was also in the system. I regret that the lateness of the hour on T.H.E Show's final day did not allow me to gather more information.
