Two brushed aluminum hourglass knobs on either side control input and volume. 

Refined industrial cosmetic design is a Mark Levinson hallmark. But in the end, it's the No.5805's output that we love the most: this integrated amp will give you the kind of huge, detailed sound and low noise-floor that only "big iron" — a massive transformer — can deliver.

Mark Levinson No5805 -- front

Mark Levinson's No.5805 integrated amp features a refined industrial cosmetic design.

Expansive soundstage for digital and analog sources

Here is a single, stout component that reproduces digital and analog sources with an expansive soundstage that is high, wide and deep. 

The amplifier's beefy toroidal transformer underpins the dual mono, discrete component circuitry to produce an amazing accuracy of tone, timbre and dynamics. Whatever recording you happen to play, the '5805 gives you an energetic, lifelike rendering. 

Treat your vinyl right

Mark Levinson put some of the time-proven technology from their highly collectible No.25 phono preamp into the onboard phono stage of the '5805. With moving coil and moving magnet modes — including an array of flexible capacitive and resistive loading switches on the rear panel — the '5805 allows you to get the best out of your favorite cartridges.

High-current output

The '5805 is also supremely flexible when it comes to your choice of loudspeakers. Four 10,000 microfarad capacitors per channel deliver 125 watts x 2 into 8 ohms, and 250 watts x 2 into 4 ohms, with consistent stability down to 2 ohms. In plain terms, it can cleanly power practically any speaker set you choose.

A legacy that sets the bar high

Since the company's inception in 1972, Mark Levinson has set world-class standards for quality, musicality and longevity. If you're lucky enough to find a vintage piece, the asking price may be higher than the original. And they're still designed and built in the USA.

We are thrilled that the recently developed 5000 Series brings the legendary sound of this brand into the realm of the attainable for more music lovers.

Product Research



High Performance Integrated Amplifier: The No5805 integrated amplifier is designed to deliver all of the performance and quality expected from Mark Levinson, while implementing state of the art features and efficiencies gained from decades of superlative audio engineering. The Mark Levinson No5805 contains a high-performance preamplifier and class-A/B amplifier in one beautiful, iconic piece, so you can experience dynamic and vibrant digital audio. Feel the very soul of the artist's performance with this Mark Levinson 5000 Series integrated amplifier that delivers powerfully pure sound.

Class-A/B Amplification: With pristine class-A/B dual-mono amplification and a highly capable power supply, the No5805 delivers an abundance of power to your loudspeakers and fills an entire room with rich, distortion-free sound.

  • Oversized Toroidal Transformer: The fully discrete, direct-coupled, Class AB amplifier channels get their power from an oversized (500+ VA) toroidal transformer with individual secondary windings for the left and right channels. The voltage gain stage employs a topology directly descended from Mark Levinson's acclaimed No534 amplifier, which is mated to an output stage comprising two high-speed driver transistors operating in Class A and six 260V, 15A output transistors.
  • Low-Impedance Operation: Two Thermal-Trak devices in a unique configuration guarantee stable output bias regardless of load or temperature. Four 10,000-microfarad capacitors per channel, located directly on the output stage circuit board, easily provide enough current for a conservative 125 watts x 2 channels (at 8 ohms) and 250 watts x 2 channel (at 4 ohms), and stable operation down to 2 ohms.

Note: The amplifier section of this unit can be turned off so that it will operate solely as a preamplifier or headphone amplifier.

Pure Path Circuit Design: The foundation of the No5805 is its proprietary PurePath circuitry - a fully discrete, direct-coupled, dual-monaural line-level preamp circuitry, for which the Shelton design team has filed two patent requests. Mark Levinson's proprietary Pure Path circuit design maximizes audio signal integrity with exceptional accuracy and sonic clarity from this high-end integrated amplifier with a premium phono pre-amp stage. A unique single gain stage mated to a digitally controlled resistor network for volume adjustment maintains maximum signal integrity and widest possible bandwidth. Each of its three stereo line level inputs - one balanced XLR and two single-ended, using custom Mark Levinson RCA connectors - has its own individual high-reliability signal switching relays.

Hybrid Gain Phono Stage: A newly designed phono stage features a hybrid gain topology, mating key discrete components from Mark Levinson's acclaimed 500 series Pure Phono stage with low-noise integrated circuits for high performance at lower cost. Also like the 500 series, a hybrid active/passive RIAA equalizer employs precision resistors and polypropylene capacitors for exceptional accuracy and sonic clarity. You are able to select MM/MC gain and optional infrasonic filter from the setup menu, while capacitive and resistive loading settings are easily accessed from the rear panel.

Precision Link II Digital-to-Analog Converter (DAC): The No5805 offer outstanding digital audio capability through the Mark Levinson Precision Link II DAC. The latest generation ESS Sabre 32-bit D/A converter with jitter elimination circuitry and a fully balanced, discrete current-to-voltage converter form the heart of the digital audio processing stage. The Mark Levinson No5805 accurately reproduces digital audio signals and minimizes noise, so you can discover new details in your favorite songs. You'll experience outstanding audio quality from your entire digital music collection. The unit supports PCM, DSD, and MQA playback with seven user selectable PCM filters and four lowpass filters for DSD playback.

  • PCM: The No5805 offers support for 32, 44.1, 48, 88.2, 96, 176.4, 192, 352.8, and 384kHz PCM. You can set the filter characteristic for PCM digital content such as the digital output from a CD player. Try several of these filters with the types of music you typically listen to and choose the one you prefer. Choose from Apodiz Fast, Hybrid Fast, Brickwall, Fast Linear, Slow Linear, Slow Minimum, and Fast Minimum.
  • DSD: The No5805 supports DSD Native/DoP 2.8, 5.6, or 11.2MHz. You can set the low-pass filter characteristic for DSD high-resolution digital content. You can select from roll-offs that begin at 47kHz, 50kHz, 60kHz or 70kHz. The audible effects of the different roll-off characteristics are subtle and will vary depending on the type of musical content and the high-frequency bandwidth of your speakers and headphones.
  • MQA: The Mark Levinson No5805 integrated amplifier offers full MQA (Master Quality Authenticated) decoding technology, which enables playback of MQA audio files and streams from any digital input - including USB-B, Optical, Coaxial, and AES. MQA delivers sound of the original master recording in the highest possible sound quality. At this level of playback you are hearing what was created in the studio - with precise file and platform-specific DAC compensation and management.

352.8kHz or 384kHz PCM Upsampling: Upsampling is the process of increasing the effective sampling rate of a digital audio signal. PCM signals at 44.1, 88.2, or 176.4kHz are upsampled to 352.8kHz; while PCM signals at 48, 96, and 192kHz are upsampled to 384kHz. Because these lower resolution signals inherently have fewer samples per second, it is impossible to perfectly recreate the additional samples that would have been present in a higher resolution signal. However, the advanced up-sampling algorithm of the No5805 is able to approximate these additional data points very well, and with most program material it offers a noticeable improvement.

Class-A Analog Headphone Stage: The No5805 features a MainDrive headphone output which employs a preamp output stage specifically designed with the current and power capacity to drive headphones directly in pure class A, without a separate headphone amp. As a result, you'll unleash all the performance your headphones can deliver with the Mark Levinson No5805 for an incredibly personal listening experience.

Surround Sound Processor (SSP) Mode: The SSP (Surround Sound Processor) mode allows the No5805 to be seamlessly integrated into a multichannel home cinema system. Any analog input may be designated as the surround sound processor input. When the SSP mode is activated the No5805's volume control is deactivated and the level is fixed at unity gain. This allows the Surround Sound Processor to control the volume of the Left and Right speakers powered by the No5805 in unison with the rest of the system. Room correction EQ and level calibrations performed in this mode and stored in the surround sound processor will be maintained unaltered.

Note: Prior to entering SSP mode make sure the volume of your surround sound processor is all the way down. Gradually increase volume as desired and perform calibration.

Audio Settings: The No5805 integrated amplifiers offers several audio adjustments for volume, mute, and source level.

  • Max Volume: This setting determines the maximum volume level setting in 0.5dB increments between 40.0dB and 80.0dB. The factory default maximum volume is 80.0dB. Set this value to the volume slightly below where your speakers start to distort audibly.
  • Turn-On Volume: This control lets you set the initial volume upon turn-on. Choose a turn-on volume level in 0.5dB increments between 10.0dB and 60.0dB. The factory default setting is 40.0dB. You can also set the turn-on volume level to the last used volume setting.
  • Mute Level: This setting lets you set the amount of Speaker output and Line output level attenuation that occurs when the Mute button is engaged, in 0.5dB increments between -10dB and -80.0dB. The factory default mute attenuation is -40dB.
  • Offset Adjustment: The output level of audio devices can vary from brand-to-brand and model-to-model, making some devices play louder or quieter than others. The Offset adjustment allows you precisely compensate for source volume differences so that all connected devices play at a similar volume level. The setting offers a range of -12.0dB to +12.0dB, in 0.5 dB steps.

Robust & Luxurious Design: From the gently curved profile to the beautiful glass panel, the No5805 is meticulously designed to exude excellence and luxury. Robust materials, lavish finishes and bold geometry are celebrated attributes of Mark Levinson designs. One-inch thick solid aluminum front panels are bead-blasted, black-anodized, and machine contoured to flow seamlessly into the sleek glass display, which itself is recessed into a bead-blasted and clear-anodized aluminum bezel. Two iconic hourglass knobs are machined with a gently curved profile softly transitioning into a rounded front. Meticulous artistry is evident in the fine details including debossed top cover vents, screen printing behind the glass panel and aluminum Standby and Menu buttons - all resting on matching custom aluminum feet.

Protection Circuitry: If the No5805 encounters a potentially damaging condition, its built-in protection circuitry will shut off the amplifier and the front-panel display will show error messages listed below.

  • DC Detected: The indicated amplifier channel has detected DC on the output, which can damage speakers.
  • Over Temperature: Indicates the amplifier channel has exceeded thermal limits.
  • Over Current: Indicated amplifier channel has exceeded current limits.


Balanced & Unbalanced Inputs: The Mark Levinson No5805 is outfitted with both balanced & unbalanced analog audio inputs. There is one stereo balanced XLR input and two stereo unbalanced RCA inputs. Balanced connections guard against induced noise and allow long cable runs without compromising sound quality. Any analog input can also be designated as the Surround Sound Processor (SSP) input.

MM & MC Phono Inputs: The No5805 has two stereo analog phono preamplifier inputs that accept left-channel and right-channel moving magnet (MM) and moving coil (MC) phono cartridge input signals. Connect a turntable equipped with a moving coil cartridge to the MM inputs. Connect a turntable equipped with a moving coil cartridge to the MC inputs. You may connect only one turntable to the N05805. If the turntable is equipped with a ground wire, connect it to the ground screw. There is also an infrasonic "rumble" filter that can be turned on or off.

Note: The DIP switches adjacent to the phono inputs set the input Resistance for moving coil cartridges and the input Capacitance for moving magnet cartridges. Selecting the right setting is essential for getting the best performance from your turntable. Consult the cartridge's manual for the recommended load setting and follow the chart in the owner's manual of the No5805 to make the correct settings.

Digital Audio Inputs: The Mark Levinson No5805 is outfitted with a total of 3 digital audio inputs; including two optical (toslink) digital inputs and coaxial (RCA) digital input. All digital inputs support 2ch stereo playback from PCM (up to 32-bit/384kHz), DSD (up to 256/11.2MHz), and MQA music files. It is not compatible with Dolby Digital, DTS, or other multichannel audio formats.

Asynchronous USB-B Port: The No5805 integrated amp is equipped with an asynchronous USB-B port for connection to your Windows PC (7-up) or Mac computer (OSX 10.4-up), so you can play music files stored on your laptop or desktop through the Mark Levinson integrated amplifier. The USB-B input allows playback of PCM (up to 32-bit/384kHz), DSD (up to 256/11.2MHz), and MQA music files. A Windows PC will require a dedicated USB audio driver; a Mac does not require an additional USB audio driver.

Note: There is also a rear-panel USB-A port that is used for firmware updates only. The USB-A port does not support audio playback.

Bluetooth aptX-HD: The No5805 features Qualcomm aptX HD, the latest 24-bit High Res version of Bluetooth that is being supported by newer smartphones, tablets, and laptops. It preserves sound data through the audio transmission, resulting in a "better-than-CD" listening experience. With aptX HD, listening to music at the highest audible quality is possible wirelessly trough the Mark Levinson No5805 integrated amplifier.

  • Playback: You'll be able to stream stored music, music apps, and other audio content from your Bluetooth source device (such as a smartphone, tablet, laptop, or desktop computer) to the No5805 integrated amp.
  • Control: You can control basic playback functions (such as Play/Pause & Previous/Next Track) from the included IR remote; advanced music navigation will still need to be done from your Bluetooth source device.
  • Pairing: You can pair multiple device with the No5805, but only one Bluetooth source device can be connected and used for playback at a time.

Note: Your Bluetooth source device must also support Qualcomm aptX HD to enjoy wireless HD audio. If your device does not support aptX HD, you can still enjoy standard Bluetooth audio streaming.

Binding-Post Speaker Terminals: The No5805 utilizes gold-plated, high-current loudspeaker binding posts. The positive binding posts, labeled + (positive), are red; the negative binding posts are black and are labeled - (negative). The binding posts can accommodate speaker cables terminated in untinned bare wire (up to 10AWG), spade lugs and banana plugs (single only).

Note: Use high-quality 16AWG speaker or larger to ensure the highest fidelity performance.

Stereo Analog Line Outputs: Variable stereo analog line-level RCA outputs allow system expansion and flexibility. These stereo RCA jacks provide a line-level left-channel and right-channel signal that can be used to send the selected input to an amplifier connected to speakers in a second listening room, or a recording device.

Note: The Line outputs are variable and will follow the integrated amp's Volume, Balance and Mute controls.

Front-Panel Headphone Output: The No5805 is outfitted with a front-panel 1/4" TRS headphone jack. The integrated amp's speaker and line outputs automatically mute when a set of headphones are plugged in.


Front Panel Display: The front-panel 32-character alphanumeric display provides information about the No5805's operating status. During normal operation, it indicates the name and volume level of the selected input.

IR Remote: An elegant 5000 Series custom aluminum IR remote control is included for wireless operation of the Mark Levinson No5805 integrated amplifier. The remote provides control functions such as Power On/Off, Input Selection, Volume Up/Down, Mute, Balance, Play/Pause, Previous/Next Track, Stop, Menu Selection.

Customer Q&A

1 question already asked

Question for your Advisors. I DID buy the MarkLevinson 5805 ampli and the 5101 CD/SACD player from you. Months later, I asked to M-L if the CD player could play/decode MQA CDs. They told me it cannot. Now I thought: maybe the ampli CAN decode the MQA even if the CD player cannot. In fact it can decode MQA files streamed on the Net, no ? What do you think ? Or should I ask M-L directly ? Stefano Farris
[ STEFANO  Mar 27, 2023 ]
1 answer
That sounds like correct intel from Mark Levinson direct, Stefano. This is quite an exquisite pair, and the No.5101 CD player has some impressive disc file support below. It does not support MQA from disc playback or through its onboard DAC. DSD (up to 5.6MHz), FLAC (up to 24-bit/192kHz), WAV (up to 24-bit/192kHz), AIFF (up to 24-bit/192kHz), OGG (up to 24-bit/192kHz), AAC (up to 24-bit/96kHz), WMA (up to 192kbps/48kHz), and MP3, (up to 320kbps/48kHz). Now your 5805 amplifier is a different story completely, the 5805 integrated amplifier offers full MQA decoding technology, which enables playback of MQA audio files and streams from any digital input - including USB-B, Optical, Coaxial, and AES. When listening to MQA's, make sure you are connected to the amplifier directly with your input of choice. I hope this helps!
