Mono Block Power Amplifier Mark Levinson No. 531 H

In the vote of their monoblocks Mark Levinson No. 531 H (12800 euros the pair) the Americans have thought less of high-end wimps than on fanatical lover of truth.

  2. Data sheet

The Mark Levinson high end forge reasonably assumes that their clients not in narrow stalls of student lives. Therefore disturbs anyone, that the Mono blocks No. quite oversized housing got 531 H. Fit into the same cabinet at the 532 and 533 loose even a second and a third amplifier module.

To emphasize air and material, such as to the disparity, the engineers constructed their input stages of Auflöten components. Together with shorter and more solid bedding symmetric circuit board paths increase signal speed, but also a group that surrendered the (including a number of opto-couplers, which correspond to the protection circuit) fits on a few square centimetres.

On top of that, the Americans use small not more like once a few huge Elko power storage, but many. Parallel groups reduces the inductance of the connection and the discharge time – the construction but is little for the eye.

The look starts instead of four horizontally and vertically symmetric the output transistors of the bridge amplifier that can deliver big strokes about two hot terminals despite relatively of low operating voltage.

With pulse advantage, beautiful Brown metal film Quartet replace the usual cement resistors. Also the toroidal transformer, who received a shielding against interference, makes her a lot. Finally, the 531 owner is happy that he switched his Mono blocks not only using the trigger voltage and turn off, but also via Ethernet Jack in a Crestron control network can incorporate.


To say it right: when voting their monoblocks thought Americans less at high-end wimps than on fanatical lover of truth. As a huge, newly polished glass they look inside the music, to reveal the finest bass contour grain, the softest nuance of voice or the tiniest amount Straehlchen crystal clear.

All their precision managed to create the no 531 also infernal pressure – since the Vincent violence blocks laid down self. So were the new MLs when the really big amps and there as the very jagged.
