米国大手半導体メーカーのインターシル社(現ルネサス)とトップレベルのエンジニアチームと提携し、創業者マーク・レビンソンの先見的なアイデアからMighty Catと呼ばれる独自の半導体を開発

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

Maria contains, in one chassis:
Preamplifier with 3 analog and 3 digital inputs
WiFi Receiver
Embedded DH Mighty Cat Audio Software Suite
Active Crossovers
C Wave Technology
Speaker Tuning
Headphone Jack
Headphone Tuning
Power Amplifiers x 4 Channels
Regulated Power Supplies (90-250V)
DH Speaker Connectors
DH Speaker Connector Tightening Tool

Quality and simplicity
Maria is a minimalist, elegant design with unparalleled performance, ease of use, and unique advantages. In a world that pushes mediocrity and complexity, Maria stands for uncompromised quality and maximum simplicity.
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.
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 using old technology.
C Wave
DH patent-pending C Wave technology offers the sound and feeling of pure analog audio from all sources including digital content, opening the door to streaming with natural sound previously impossible to obtain.
New technology
The new Daniel Hertz amplifier technology, including main motherboard, power supplies and output stages, enables the most natural sound with stunning dynamics, punch, detail and imaging, with no electronic sound, beyond the limitations of typical “tube” and “transistor” equipment. Many engineering advances and refinements add up to maximizing the benefits, to obtain a unique listening experience unavailable any other way.
Digital to analog conversion with 384kHz native resolution, no separate DAC
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.
All preamplifier functions
The main functions of a preamplifier include input selector, precision volume control, optimum input parameters, optimum output parameters, high linearity, low distortion, low crosstalk, low noise and high headroom (no clipping). Maria includes the functions of the most expensive preamplifiers – and much more – with maximum performance, reliability, and ease of use.
¼” headphone output on the front panel
A ¼” headphone jack is provided on the front panel on the right. A polished stainless steel knob screws into the front panel so the jack is covered when not in use. The DH Maria’s embedded software includes headphone tuning capability to optimize the performance of any headphone.
1 megohms analog inputs
1 megohms analog inputs The DH Maria has 3 analog inputs that can be used 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 material and analog recordings that have been digitally remastered and then produced in LP format. (many so-called “analog” LP’s are digitally mastered). Maria faithfully reproduces all content regardless of the format.
Digital inputs and WiFi
3 digital inputs are provided: USB, Coax and WiFi (with a module that also offers high resolution Bluetooth). Macs and PC’s are hard wire connected via the USB input; professional equipment often uses coax; and any device with WiFi or Bluetooth – computers, phones, tablets and mobile phones – can use the wireless input provided by the receiver module on the rear panel. 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. Sound quality with WiFi is superb, similar to hard wired.
Daniel Hertz Speaker Connectors designed and made in house
DH speaker connectors, made in house, go beyond “high end audio” standards. Instead of adding soldered 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 unimprovable quality of connection that never degrades. The 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.
