Mark Levinson Unveils the 600 Series: A Sculpted Symphony of Analog Purity and Digital Precision

The revered hi-fi marque returns with a glowing tease of its next-generation preamp and amplifier lineup, promising dual-monaural design, Pure Path fidelity, and high-end American craftsmanship.

Mark Levinson, the flagship audio brand under Harman Luxury Group, has offered a tantalizing glimpse of its upcoming 600 Series — a trio of high-end electronics that marry old-school analog devotion with state-of-the-art digital flexibility.

Unveiled in a sleek, under-the-radar showing at High End Munich 2025, the new lineup includes:

• No. 626 Dual-Monaural Preamplifier

• No. 632 Dual-Monaural Amplifier

• No. 631 Monaural Amplifier

  
  

Designed, engineered, and assembled in the USA, the 600 Series carries forward Mark Levinson’s signature Pure Path circuit philosophy, blending uncompromising component quality with precision circuit topologies in fully balanced configurations.

Visually, these machines are unmistakable: thick machined aluminum enclosures sculpted with the brand’s trademark Tectonic industrial design, accented with deep black finishes and a glowing undercurrent of red ember lighting, designed to evoke “volcanic glass.” Mark Levinson doesn’t just build components — it sculpts icons.

No. 626 Preamplifier: Dual-Monaural Design with Digital Soul

The No. 626 sits at the heart of the new lineup. It’s a fully dual-monaural preamplifier built on an all-analog backbone — complete with separate left and right channels, isolated power supplies, and a modular architecture that invites future upgrades.

But this isn’t a throwback piece. Inside, the 626 is loaded with digital flexibility, thanks to the onboard Precision Link III DAC, capable of decoding:

• PCM up to 32-bit/384kHz

• Native DSD decoding

• Six digital inputs (USB, coaxial, optical, etc.)

  
  

Analog lovers haven’t been forgotten either — there’s a Pure Phono MM/MC stage for vinyl playback and a Main Drive Class A headphone amp, underscoring the preamp’s role as an all-in-one control hub for both loudspeakers and headphones.

No. 632 Amplifier: Balanced Power, Modular Muscle

The No. 632 Dual-Monaural Power Amplifier is designed to pair perfectly with the 626, forming a balanced signal path from source to speaker. Though Mark Levinson has held back on publishing specific power output ratings, the emphasis is clearly on headroom, current delivery, and low-noise architecture.

Key highlights include:

• Fully Balanced Class A/AB topology

• Dual-mono layout in a single chassis

• Independent toroidal transformers per channel

• Modular internal structure for enhanced thermal and EMI management

  
  

From the looks of its rear panel and massive heatsinks, it’s safe to assume the 632 will offer substantial output, likely tailored to drive even the most demanding loudspeakers with ease and authority.

No. 631 Amplifier: True Monoblock Precision

For systems that demand ultimate channel separation, the No. 631 Monoblock Amplifier doubles down on the 632’s core architecture — but splits it across two physically independent chassis. This isn’t just about brute force; it’s about channel isolation, imaging precision, and electrical symmetry.

Each 631 runs in Class A/AB, with its own robust power supply, optimized grounding, and minimalist signal routing — keeping the signal path as pure and uninterrupted as possible.

These are amplifiers aimed at audiophiles who want the very best in spatial fidelity and dynamic authority — the kind of system that can render silence as vividly as it does crescendo.

Availability: The Tease Before the Arrival

The 600 Series reveal at High End Munich was, in essence, a preview — not a full launch. According to Mark Levinson, all three components are still in final stages of development, with shipping expected by the end of 2025.

Pricing details remain under wraps for now, but considering the brand’s past offerings — and the attention to design, materials, and modularity on display — these will firmly land in the reference-class tier.

Final Take: Modern Mastery in the Making

With the 600 Series, Mark Levinson is making a clear statement: that high-end audio in 2025 doesn’t need to choose between analog purity and digital sophistication — it can deliver both in one sculpted, luminous package.

This is a system for the discerning listener — one who appreciates dual-mono circuit architecture, future-ready modularity, and the visceral joy of gear that looks and feels as serious as it sounds.

The 600 Series isn’t just about sonic excellence. It’s about presence — in your room, in your rack, and in your listening experience.
