Maria 200

The Mighty Cat™ Class D chipset is at the heart of the Maria 200. It is a DAC with analog power output that has a native resolution of 384kHz. Mighty Cat™ has the most elegant and shortest signal path possible, eliminating signal degradation by multiple chassis systems with many meters of cable, power supplies and loading issues

Mighty Cat™ has no audible noise. High output current and low output impedance enable Mighty Cat™ to drive all high quality speakers with ease. Power supply regulation, a rare and costly feature of only a few pure analog amplifiers, is provided by a state-of-the art SMPS (switching mode power supply), enabling rock solid bass, astonishing punch and dynamics, and pin point imaging. 3 analog inputs have one megohm input impedance, an innovation introduced by Mark Levinson, which eliminates loading of analog source devices

Maria 200
The audio industry pushes expensive speaker cables that put the stereo signal through 4 solder joints and 4 additional pieces of metal. Daniel Hertz speaker connectors eliminate these unnecessary sources of signal degradation by sandwiching the bare copper wire between two brass plates, making a connection with no virtually no limitations in voltage and current, that last a lifetime, and are able to accept almost any size wire. The threaded rod that is the mechanical and electrical connection attaches to the amplifier output stage located inside the chassis, only millimeters away from the connector, adding no extra wire or materials to the signal path.
The Maria is as new on the outside as it is on the inside. Maria's chassis is made of hand-assembled art-grade black mirror finish Perspex panels, with hand-polished stainless steel knobs and buttons. Typical amplifiers made of anodized aluminum have the look of an appliance. The Maria Amplifiers are closer to the quality of fine jewelry. Maria's chassis is artisan made, not industrially produced, and is at home with in luxury home interiors and architecturally designed spaces. Daniel Hertz is the only audio company that designs and builds its own speaker connectors. They are made from machined Delrin ® and brass with a speaker connector tightening tool made from Delrin ® and stainless steel. Additionally, the Maria 200 has an added bonus of being able to be upgraded to the Maria 800. Please reach out to a Daniel Hertz Expert to inquire about this exciting option.
