Introduction

Mark Levinson is one of the world's great high end audio manufacturers. They make a wide variety of electronic components, including pre amps, DACs, CD transports, SACD players as well as a surround sound processor they call a "Media Console". Levinson has also teamed with luxury auto manufacturer, Lexus so you can take their audio products on the road. Nonetheless, Mark Levinson is almost certainly best known for their very large, very powerful and very expensive power amplifiers. They enjoy a well deserved reputation for making some of the best - if not the best - solid state power amps around.

The Nº 531H is from a series of four new Mark Levinson power amplifiers. The amplifiers in the Nº 500H series are available in 1, 2, 3 and 5-channel configurations. Each model uses the same chassis. The Nº 531H's are monoblock amplifiers that are rated at 300 watts per channel into an 8 Ω load. A first for Levinson is that the 3 and 5-channel models are quasi-monoblock designs. The Nº 500H Series of amplifiers are the most affordable amplifiers from a true high end company.
