Mark Levinson Nº 5805 – Integrated Amplifier with DAC & MM/MC Phono Stage

Vinyl. Digital. Bluetooth. Pure Mark Levinson.

The Mark Levinson Nº 5805 brings together the essential components of a serious two-channel audio system in one beautifully engineered integrated amplifier.

Delivering 125 watts per channel into 8 ohms and nearly 250 watts per channel into 4 ohms, the Nº 5805 combines powerful Class AB amplification with a sophisticated analog preamplifier, a Precision Link II DAC, and a dedicated moving-magnet/moving-coil phono stage.

Connect a turntable, CD transport, music streamer, computer, or Bluetooth device and enjoy them through the same carefully engineered amplification platform.

At its heart is Mark Levinson’s proprietary Pure Path circuitry, supported by a substantial toroidal power supply and fully discrete amplifier channels derived from the brand’s acclaimed Nº 534 power amplifier.

For listeners who want reference-oriented performance without an equipment rack full of separates, the Nº 5805 offers an elegant way to build a complete music system.

Powerful Amplification. Exceptional Control.

The Nº 5805 is designed to do more than simply make music louder.

Its fully discrete, direct-coupled Class AB amplifier channels draw on circuitry developed for Mark Levinson’s Nº 534 power amplifier.

Each channel employs Class A driver transistors and a high-current output stage supported by an oversized toroidal transformer. Separate transformer secondary windings supply the left and right channels, while four 10,000-microfarad capacitors per channel provide local energy reserves.

The amplifier delivers 125 watts per channel into 8 ohms, with output approaching 250 watts per channel into 4 ohms. Mark Levinson also specifies stable operation into loads as low as 2 ohms.

This substantial electrical foundation gives the Nº 5805 the capability to drive a wide range of demanding loudspeakers while maintaining control through dynamic musical passages.

 

Pure Path: Where Great Sound Begins

The Nº 5805 incorporates Mark Levinson’s proprietary Pure Path analog circuitry.

Its fully discrete, direct-coupled, dual-monaural preamplifier design maintains dedicated signal paths for the left and right channels.

A single gain stage works with a digitally controlled resistor network for volume adjustment, while individual signal-switching relays serve each line-level input.

The objective is to preserve the integrity of the incoming signal before it reaches the power amplifier.

Whether you're listening to an analog source or music converted by the internal DAC, the Nº 5805 is engineered to retain the detail and dynamics of the recording.

 

A Serious Phono Stage for Your Turntable

Vinyl enthusiasts haven't been forgotten.

The Nº 5805 incorporates a dedicated phono stage supporting both moving-magnet and moving-coil cartridges.

Its hybrid gain architecture draws on elements of Mark Levinson’s 500 Series Pure Phono design, combining discrete components with low-noise integrated circuitry.

A hybrid active/passive RIAA equalization network employs precision resistors and polypropylene capacitors for accurate playback equalization.

Cartridge gain and the infrasonic filter can be configured through the amplifier’s setup menu, while loading adjustments are accessible from the rear panel.

This flexibility allows the Nº 5805 to accommodate a range of turntables and cartridges without requiring a separate phono preamplifier.

For listeners building a vinyl-focused system, The Grid HiFi can help match the turntable, cartridge, and phono settings for proper operation.

 

Precision Link II: High-Resolution Digital Audio

The Nº 5805 is equally capable with digital music.

Its Precision Link II DAC incorporates an ESS Sabre 32-bit converter, proprietary jitter-reduction circuitry, and a fully balanced, discrete current-to-voltage conversion stage.

Four digital inputs provide connectivity for a variety of sources:

• One asynchronous USB-B input

• One coaxial digital input

• Two optical digital inputs

Through compatible playback methods, the DAC supports PCM up to 32-bit/384kHz and DSD up to 11.2MHz.

Connect a CD transport, network streamer, television with compatible optical output, or computer and let the Nº 5805 handle digital-to-analog conversion.

Important: The Nº 5805 includes a DAC and Bluetooth receiver, but it is not a standalone network music streamer. A separate streaming source is required for services such as Qobuz or TIDAL.

 

Bluetooth with aptX HD

Sometimes you simply want to play something from your phone.

The Nº 5805 includes a Bluetooth receiver supporting aptX HD, providing convenient wireless playback from compatible devices.

It’s an easy way to share music with friends, discover a new album, or enjoy casual listening without changing your primary source setup.

For dedicated high-resolution playback, use a compatible wired digital source through the Precision Link II DAC.

 

Class A Headphone Listening

The Nº 5805 includes a front-panel ¼-inch headphone output driven by its Class A analog line-stage circuitry.

This provides a dedicated option for private listening without requiring an additional headphone amplifier.

Whether you're enjoying an album late at night or listening closely to a familiar recording, the integrated headphone connection adds another dimension to the amplifier’s versatility.

 

Build a Complete Music and Home Theater System

The Nº 5805 is designed to accommodate an entire collection of audio sources.

Its analog inputs include a balanced XLR stereo pair, two line-level RCA stereo pairs, and a dedicated MM/MC phono input.

Variable stereo RCA outputs provide flexibility for system expansion, including connection to compatible external amplification or powered subwoofers.

For listeners combining two-channel music and home theater, the amplifier’s SSP pass-through mode allows a compatible surround processor to control volume for the front left and right channels.

Ethernet, RS-232, infrared, and programmable 12V triggers provide additional integration options for professionally installed systems.

The Ethernet connection supports configuration and control; it does not turn the amplifier into a network audio streamer.

 

Signature Mark Levinson Design

The Nº 5805 carries the unmistakable styling of the 5000 Series.

A substantial, one-inch-thick black-anodized aluminum front panel flows into a recessed glass display framed by clear-anodized aluminum.

The signature hourglass-shaped control knobs are precision-machined with gently curved profiles, while matching feet and carefully detailed ventilation complete the design.

A custom aluminum infrared remote is included.

Designed, engineered, and precision-crafted in the United States, the Nº 5805 combines premium construction with the functionality of a modern integrated amplifier.
