Mark Levinson Nº585 Integrated Amplifier

Description

The Nº585 Integrated Amplifier is Mark Levinson's most accomplished integrated integrated to date, combining the brands unsurpassed analog performance with advanced digital audio capability and flexible system configuration – not only are the standard analogue connection available, but the Nº585 have a fully integrated DAC capable of direct decoding of source material up to 32Bit/192Khz and both single and double rate DSD. The No585 pushes the reproduction of any source material to new levels of realism, with extraordinary levels of audio performance in high-end audio design like no other.

Reference AV say:

_“The Mark Levinson Nº585 is a stunning product that brings their product line-up right to the peak of the technology curve. The sheer amount of flexibility that comes from being able to accept both analogue and digital inputs, including high rate DSD, with integrated Levinson amplification on board, make this unit an extraordinary bargain. _”

Incredible Solid State Musical Performance

The foundation of the No585 is its fully discrete, mirror-imaged, dual-monaural analog circuitry featuring individual signal switching relays for each of its four stereo inputs: one XLR and three RCA.

Volume controls use discrete 15-bit R-2R ladders and low-noise analog switches for the widest possible bandwidth and maximum signal integrity. The fully-differential Class AB power stage includes an oversized 900VA toroidal transformer with individual secondary windings for the left and right channels.

Each elegantly simple amplifier channel utilizes twelve output transistors and multiple smaller local capacitors that allow them to be placed physically closer to the amplifiers for greater transient response when power is needed immediately.

This robust architecture results in a conservative power rating of 200W per channel with stability into 2 ohms. System integration and expansion are possible using the stereo RCA preouts which can operate full-range or with an included switchable, second-order, 80Hz crossover filter allowing for seamless integration into 2.1-channel systems with powered subwoofers.

Audio Chassis:

Building upon this superb analog platform, the N0585 adds equally outstanding digital audio capability. An ESS Sabre 32-bit D/A converter with proprietary jitter elimination circuitry and fully-balanced, discrete I/V circuitry forms the heart of the digital audio processing stage. Six digital audio inputs are provided including one AES/EBU, two coaxial and two optical plus a USB audio processor capable of asynchronous data transfer of high resolution DSD and PCM files at up to 192kHz/32 bits resolution. For low-resolution audio formats, proprietary ClariFi™
signal processing reconstructs information and bandwidth lost in compressed file formats restoring them to higher fidelity. System integration and communication ports include Ethernet, USB, RS-232, IR input, and 12V trigger input and output. A
system IR remote control is included.

Construction:

The chassis of the N0 585 utilizes card-cage architecture to isolate critical low-level analog and digital circuitry from the power supplies and amplifier modules. The steel and aluminum construction features internal amplifier heatsinks and Mark
Levinson’s iconic black and silver anodized aluminum front panel with its intuitive twin-knob control system and unique red display.
