product description image

At Daniel Hertz, we believe that “No compromise” is not marketing hyperbole; it lives in the engineering, craftsmanship and attention to detail in everything we do.

Eva Reference Speakers

Most compact speakers lack natural sound and deep bass. Eva uses highly engineered drivers, a crossover and cabinet, personally tuned by Mark Levinson to deliver astonishingly natural sound and deep bass to below 30Hz, with wide dynamic range and flexibility at affordable cost.

The Daniel Hertz Eva has a 1” silk dome tweeter, high resolution 6” woofer, precision crossover, ported 25mm thick enclosure, high quality connectors, and a flawless black piano finish.

Maria 50

The Mighty Cat® Class D chipset is at the heart of the Maria 50. 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 50
The Maria 50 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 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.
