Nº532H
Amplifiers
(Print this page)OVERVIEW
The No531H and No532H are both true mono-block designs with independent power supplies for each channel and are rated at 300W per channel into 8 ohms. The transformers and power supply designs deliver unsurpassed dynamics and transient responses for today’s demanding audio formats and provide stability with even the most difficult to drive loudspeakers. Fully differential circuitry ensures that balanced input signals stay that way throughout the signal path and traditional Mark Levinson “Hurricane” binding posts offer secure termination to the loudspeaker.
The four amplifiers in the No500H Series are the definition of truly outstanding performance in their respective categories. Drawing from the Mark Levinson heritage, while utilizing a new, straightforward, balanced, current-feedback design creates a new series of amplifiers that must be listened to in order to be fully appreciated. The final result is impressive even for the Mark Levinson high standard of excellence.
