The M4 Reference System

The M4 Reference System is a more compact version of the flagship M1. The M4 was created to put the M1's incredibly high standard into a living room size speaker. The Daniel Hertz M4 reference bi-amplified system is the finest living room sized system Mark Levinson has ever created.

M4 Reference Speakers

The M4 is designed to deliver no compromise sound in a living room environment. The M4 is the only speaker of its size that creates an emotional experience that challenges live music. Using state of the art pro audio technology with proprietary refinements, the M4 has an efficiency of 95dB/1W/1M/8 ohms.In practice, most listening consumes less than 1W of power.

The compression driver tweeter and Daniel Hertz exclusive molded horn reproduce the fine details of the most delicate instruments and also the full force of high SPL Rock and Pop tracks with sound pressure at the maximum sustainable levels.

The monster 12” Midrange reproduces the main body of the sound with extreme transparency and dynamics.The 15” Subwoofer has the speed, low distortion and power handling to shake rooms as well as recreate the subtle low level ambiance of a concert hall. Daniel Hertz speaker connectors eliminate solder joints and terminations, insuring perfect signal transmission between the Maria 800 and the M4.

M1 Reference Speakers

Maria 800

Mark Levinson personally designed Maria 800 to enable no compromise bi-amplified systems. The Maria 800 can also be operated in bridge mode to deliver 800 watts per channel, 2 channels.

The Maria 800 has fully programmable active crossovers with laboratory grade algorithms that enable the precision tuning in .1dB increments required for bi-amplifying the M4 speakers without compromise.

The Mighty Cat™ Class D chipset is at the heart of the Maria 800. 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 1 megohm input impedance, an innovation introduced by Mark Levinson, which eliminates loading of analog source devices.

Maria 800
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.
