Mark Levinson – No 5805 Integrated Amplifier
Breakthrough Mark Levinson Performance for Less: Nº 5805 Integrated Amplifier Has Dual-Mono Circuitry, Pure Direct Signal Path, MM/MC Phono Preamp, PrecisionLink II DAC
When you think of premier Mark Levinson gear, five-figure price tags normally come to mind. Which helps explain why the fully loaded Nº 5805 integrated amplifier constitutes such a breakthrough. Nothing here has been reduced. All of the company’s hallmark technology, trailblazing engineering, refined luxury, and elegant finishes remain in tact. It is meticulously handcrafted in the U.S.A. The only change pertains to a cost that immediately makes the brand more accessible to a wider audience that will get to experience the connoisseur-level fidelity, authoritative control, and do-anything flexibility that many fortunate audio listeners have known for decades.
Fully discrete, direct-coupled, dual-monaural, line-level preamp circuitry in the form of the trademarked PureDirect signal path beats as the heart of the Stereophile Class A Recommended Nº 5805. A unique single gain stage mated to a digitally controlled resistor network for volume adjustment maintains maximum signal integrity and wide-open bandwidth. All three stereo line level inputs use customized Mark Levinson RCA connectors possesses their own individual high-reliability signal switching relays.
With Nº 5805, listening to vinyl or high-resolution files in sensory-awakening sound is a breeze. A hybrid gain MM/MC phono preamplifier integrates discrete components from the company’s Nº 500 Pure Phono stage as well as an active/passive RIAA equalizer with precision resistors. Equipped with the Mark Levinson Precision Link II DAC and four digital inputs, it handles up to 32-bit/192kHz and 2x DSD. Full MQA decoding and aptX HD Bluetooth further take care of your streaming needs. if you want to plug in ‘phones, a MainDrive headphone output employs a preamplifier output stage specifically designed with the current and power capacity to directly drive any pair you connect.
In the amplification stage, fully discrete, direct-coupled, Class AB amplifier channels are fueled by an oversized (500+ VA) toroidal transformer with individual secondary windings for the left and right channels. The voltage gain stage employs trickle-down topology directly from the acclaimed Nº 534 amplifier and gets mated to an output stage comprising two high-speed driver transistors. 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, provide enough current for conservatively rated 125Wpc (eight ohms) and nearly 250Wpc at four ohms.
Nº 5805’s fortuitousness extends to its system integration abilities and Ethernet, USB, RS-232, IR input, and 12V communication ports. A solid aluminum remote control, Mark Levinson web support, home-theater pass-thru mode, and stunning industrial looks complete an integrated amplifier that takes you into another musical dimension. 100% Music Direct Guaranteed.
