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.

Chiara Ultra Dimensional Speakers

The Chiara faithfully reproduces the sound of instruments and voices with stunning accuracy that enables you to clearly hear the acoustic detail of the performance space. Chiara's hand-built Aerostriction Tweeters and 8” Woofers are the products of decades of intense engineering and artisanal craftsmanship, made in small quantities without compromise. They are available exclusively from Daniel Hertz. Mark Levinson personally designed the Aerostriction Tweeters to produce the widest sound stage available. Chiara has an exclusive 8” woofer, handmade by Daniel Hertz, with a resonant frequency of 27Hz. This enables it to faithfully reproduce the main body of recording and it pairs beautifully with the open sound of the exclusive Aerostriction Tweeters. The pairing of these drivers means that the Chiara is capable of seamlessly reproducing sound from below 20Hz all the way through 20Khz with a dynamic range of 112db SPL. Chiara's cabinet is handmade and assembled by Daniel Hertz in Italy with ultra-dense Marine Grade Plywood for superior bass and energy management.

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 800
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.
