Mark Levinson 585.5
Find a deeper connection to the music you love with the № 585.5. This integrated amplifier delivers superb performance, reproducing any source material with exceptional realism so you’re drawn into the details of your music with every single listen.
The Mark Levinson Nº 585 has swept up best in class awards and countless accolades around the world, and is now widely regarded as perhaps the finest integrated amplifier ever made.
Nº585.5 Fully discrete integrated amplifier
The Nº 585.5 redefines the
playback quality of a classic medium; by adding the same Pure Phono
stage found in the award winning Nº 523 and Nº 526 preamplifiers taking
the reproduction of any source material to new heights of realism.
Architecture
The foundation of the No 585.5 is its fully discrete, mirror-imaged,
dual-monaural analog circuitry featuring individual signal switching
relays for each of its five stereo inputs: one XLR and three RCA plus a
Stereo Pure Phono stage. Volume controls use discrete R2R 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.
Amplification
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.
Details
System integration and expansion are possible using the stereo RCA pre-outswhich 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. Pure Phono: Class A for a Classic Medium The Pure Phono stage is adiscrete design with no op-amps and operates exclusively in class A throughout, employing tantalum nitride thin-film resistors and polypropylene capacitors with exceptionally low tolerances.
A fixed-gain moving magnet (MM) section with five capacitive cartridge-loading settings, and a moving coil (MC) section with three gain settings and 10 resistive cartridge-loading settings ensures optimization for any cartridge. And an ultrasonic filter intelligently compensates for rumble and warping. The Pure Phono stage also contains physically separated channels and balanced inputs for sonic purity.
Audio Chassis
Building upon this superb analog platform, the Nº 585.5 adds equally outstanding digital audio capability. An ESS Sabre 32-bit O/A convertor with proprietary jitter elimination circuitry and fully balanced, discrete IN 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 Clari-Fi'" signal processing reconstructs information and bandwidth lost in compressed file formats restoring them to higher fidelity.
Control
System integration and communication ports include Ethernet, USB, RS-232, IR input, and 12V trigger input and output. An iconic Mark Levinson custom cast aluminum system IR remote is included with the Nº 585.5.
Construction
The chassis of the Nº 585.5 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. A newly designed 3-piece anodized brushed aluminum top cover exudes durability, elegance and quality.
