The A450m
Mono Power Amplifier
The 450 Watt MonoBlock Power Amp ~ Richard Marsh’s statement amplifier for 2005
Recognizing the growing need for greater dynamic range in home theaters and to match the capacities of the new music-recording formats -- 96kHz/24bit and higher and SACD -- Marsh Sound Design has designed two monoblock solid-state amplifiers that will deliver all the impact of film scores and full orchestral music, and at the opposite extreme, all the nuances of the soft word, the small, dynamic changes in a singer’s voice, a violin pizzicato, a harp arpeggio, even the whisper of fingers on a guitar string.
Traditionally, such musical precision has always been expensive. With what one reviewer* has called “great engineering,” designer Richard Marsh has brought to life the old proverb that “a great engineer is one who can do for a dime what anybody can do for a dollar.”
The circuits are stabilized for optimum music detail resolution, by use of special balanced "tracking" regulated power supplies. The power supplies are fitted with the designer's own components (visit www.capacitors.com for information on the AudioCap and Exotica capacitors), chosen for fine products worldwide. The signal path is "direct-coupled" from input to output for music signal purity, employing Richard Marsh's popularized concept of Servo-Control.
Remote-control operation is via motorized passive controls from ALP, known for high quality and all Marsh Sound Design line amplifiers are compatible with all fine audio products.
Complex? Yes, but elegant and effective.
