The Mark Levinson No5802 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 No5802 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.

Precision Link II Digital-to-Analog Converter (DAC): The No5802 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 No5802 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 No5802 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 No5802 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 No5802 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 No5802 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 No5802 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 No5802 for an incredibly personal listening experience.

Audio Settings: The No5802 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 No5802 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 No5802 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.
