Overview

Maria - a paradigm shift in audio amplification personally designed by Mark Levinson

Mask
Daniel Hertz produces only one amplifier – Maria – the culmination of over 50 years of experience and a masterful creation by Mark Levinson himself. The Maria 350 is a stereo (2-channel) model, while the Maria 800 is a 4-channel model with active crossovers and time alignment, enabling the driving of bi-amplified speakers. Maria offers a comprehensive audio electronics solution, replacing the digital-to-analogue converter (DAC), preamplifier, power amplifier, headphone amplifier, and interconnect cables. Fully programmable active crossovers and time alignment are provided for precise sound control.
Like the iconic Mark Levinson LNP-2 Preamplifier and Cello Audio Palette, Maria sets a new sonic standard with minimalist design and astonishing quality of finish equivalent to the finest watches and cameras.

As legendary audio journalist Bert Whyte said about Mark’s work in 1972, Maria is, “monetary considerations aside… the premier choice.”

The Daniel Hertz Maria is a high performance amplifier, hand made in Venice, Italy with artisan materials and craftsmanship never used before in an audio product.

Maria sets a new standard of excellence in sound quality and design, with many exclusive advantages for those who refuse to compromise their music. The Daniel Hertz Maria amplifier is named in honor of Mark Levinson’s mother, Maria Hertz Levinson, who in 1966 sold her cello to get the money to buy him the Italian double bass c. 1680 that he plays today. Mother’s love is a category of 1.

Audiophile's Dream Amplification

Maria 350 includes an independent, internal, no compromise separately tunable headphone amplifier with a ¼” jack on the front panel, that enhances the sound of all good headphones, especially the top high performance models.

Sound note
Seamless Analogue Transformation

Maria’s embedded Mighty Cat software suite includes exclusive C Wave technology (patent accepted and approved 2024), which upgrades all digital audio signals on the fly, including streaming, to have the sound and emotion of pure analog audio.

Sound note
Versatile Connectivity

Inputs: 3 analog 1 megohms inputs, digital coax, wifi and Bluetooth. Speaker outputs: Daniel Hertz in house made speaker connector outputs on the rear panel. Headphone jack: ¼” headphone jack on the front panel.

Sound note
Top-tier Sound Amplification
Maria’s internal, separately tunable headphone amplifier is second to none in sound quality, with precision tuning available to enhance the sound of all good headphones, especially the top high performance models.
Sound note
Effortless Speaker Driving
Although compact, light weight, low heat, and highly energy efficient, Maria 350 effortlessly drives the largest, most demanding and expensive speakers on the market, with pure analog sound from streaming, as well as the DH Eva (compact) and Amber (floor standing) models.
Sound note
Complete Accessory Package

Maria 350 is supplied with a power cord (appropriate for the country of use), a USB cable, and a carrying case. When delivered with Daniel Hertz speakers, a 4m pair of cables is included.

Build
Maria is built with proprietary new Daniel Hertz technology on the inside, and a new type of chassis on the outside that embodies the uncompromised excellence of Maria’s performance and sound quality, with hand fitted mirror black Waveglas TM chassis and hand polished stainless steel watch case quality knobs and buttons.

The Holy Grail - the sound and feeling of pure analog audio from digital content.
DH C Wave Technology is the result of 30 years of research and development by Mark Levinson and a team of experts in audio and health fields. C Wave is the first upgrade to digital audio since it was introduced in the 1970’s. C wave is the highly innovative, disruptive and proprietary technology that the world has been waiting for: a way to get the emotion of pure analog audio from all digital sources including streaming, movies, and internet audio. Imagine YouTube music sounding like the best pure analog high speed open reel tape recordings.

Sound
The sound of Maria is lightning fast, extremely smooth with no “electronic” sound, and has astonishing punch, dynamics, deep bass, imaging and detail. The sound of Maria is unavailable at any price from “high end audio” amplifiers typically using old 1970’s technology.

1 megohms analog inputs
The DH Maria has 3 analog inputs with 1 megohms input impedance to connect any device with analog outputs such as a phono preamplifier, analog tape deck, digital recorder, analog tuner, cassette deck, or a CD, SACD or DVD player with analog outputs. The 1 megohms input impedance (first introduced by Mark Levinson with his company Cello, Ltd. In the 1980’s) virtually eliminates loading of the input signals to obtain the cleanest possible sound. Maria is optimized not only for reproducing digital content, but also pure analog and digitally mastered LP’s. Maria faithfully reproduces all content regardless of the format.

Digital inputs and WiFi
Digital inputs and WiFi While hard wired usb and coax connections provide the best sound quality, Maria has WiFi and Bluetooth with excellent sound that offer the convenience of wireless. The WiFi module can connect directly to a WiFi enabled device, or via a router. Connecting the module to a router enables the device to simultaneously access the internet and play through Maria.

Digital to analog conversion with 384kHz native resolution, no separate DAC
Class D is a concept, like a V8 in car motors. Typical Class D chips may be disappointing, but DH is not. The exclusive Daniel Hertz Mighty Cat Class D amplifier IC (integrated circuit) converts digital audio to analog with no separate DAC, providing native resolution of 384kHz. Some 384kHz DAC’s alone cost 25,000 euros. The DH Maria offers resolution second to none, in a highly integrated design with the most elegant signal path that eliminates sources of coloration and degradation.

Daniel Hertz Speaker Connectors designed and made in house
DH speaker connectors, made in house, go beyond “high end audio” standards. Instead of adding 8 soldered metal speaker connectors like typical cables, DH speaker connectors sandwich the bare speaker wire between two brass plates that are tightened with a DH tightening tool made of stainless steel and Delrin, for the best signal transmisson that never degrades. Threaded brass rod connects to the power amplifier output stage inside the chassis, where it is fastened with brass nuts, only millimeters away from the speaker wire, for the shortest possible signal path.

The Secret Sauce
In partnership with Intersil (now Renesas), a major US semiconductor company, and a team of top-level engineers, Daniel Hertz developed a proprietary semiconductor called Mighty Cat, a visionary idea from founder Mark Levinson. Mighty Cat is a high-performance Class D amplifier IC (integrated circuit) with internal blocks that run the embedded, exclusive Mighty Cat software suite that is part of what makes DH disruptive. Mighty Cat is the “brain” of Maria and all DH amplifiers. Mighty Cat has fully programmable architecture which enables a new level of performance, precision and flexibility in music reproduction, as well as many conveniences and practical advantages. Mighty Cat enables re-programming and updates at any time in the future, making it a living product.
