Mark Levinson’s New 600 Series – Quick Look
All Image Credit: Mark Levinson
Mark Levinson, the Harman brand, has made a preliminary announcement of the new 600 Series of amplifiers. The range consists of three models: the No. 626 preamplifier, No. 632 two-channel power amplifier and the No. 631 monoblock. Each of these latest designs uses Mark Levinson’s fully balanced Pure Path analog circuit philosophy and the brand’s trademark Tectonic industrial design that blends a machined aluminum chassis, anodized in black, with silver controls. Glass panels on each amp together with signature red accents and lighting complete the aesthetics.
The No. 626 analogue connectivity includes two configurable balanced (XLR) and three single-ended (RCA) stereo inputs, and a Pure Phono MM/MC phono stage. A Main Drive Class A amplifier is provided to drive headphones. Internally, the No. 626 has been designed using modular isolation and includes special shielding of the power supply circuit and digital source circuitry from the analogue and phono circuitry. It also uses twin ultra-low-noise toroidal power supplies and comes fitted with vibration-damped feet to keep the amp isolated.
Digital to analog conversion is available using its Precision Link III DAC, which supports up to 32-bit/384kHz PCM and native DSD through six digital inputs; 1 x AES/EBU, two coaxial digital, two optical digital, and 1 x USB-C.
Output connectivity is provided using a stereo pair of both XLR and RCA connectors, with control available using 3.5mm IR input, Link, and 12VDC trigger I/O.

No. 632
Both the No. 632 stereo power amplifier and No. 631 monoblock feature Class A/AB amplification, Pure Path fully discrete and balanced signal paths, and large ultra-low-noise linear toroidal power supplies. Signal connectivity includes; 1 x stereo pair of selectable XLR and RCA input connectors with control provided using 1 x 3.5mm 12VDC I/O. Four pairs of speaker connections are provided using “Mark Levinson Hurricane” loudspeaker output binding posts allowing for easy speaker bi-wiring.

No. 631
The No. 631 offers selectable Hi/Lo power amplifier biasing and uses a 21 inches (53cm) floorstanding chassis. In keeping with the rest of the series, its chassis has also been machined from aluminum and is anodized in black, featuring a silver plinth as its base. Rounding of its aesthetics is a glass center panel on the front with red lighting on either side, while the top panel of the amp has a glass Core element with red accent lighting.
Signal connectivity includes; 1 x selectable XLR and RCA input connectors with control provided using 1 x 3.5mm 12VDC I/O. Two pairs of speaker connections are provided using “Mark Levinson Hurricane” loudspeaker output binding post allowing for easy speaker bi-wiring.
Unfortunately there is no mention of power output for either the No. 632 or No. 631 models yet and the current specifications are very limited.
