Mark Levinson 600 Series: No‑Holds‑Barred Amplifier

News

Out of Connecticut, Mark Levinson develops innovative, top-of-the-line hi fi audio that are sure to impact what high-end amplifiers and preamps can do. The HIGH END Munich 2025 brought about three new models from this line: the No. 626, a preamplifier; the No. 632, a stereo power amp; and the No. 631 monoblock, designed using the Pure Path circuit to ensure maximum purity and total dual mono separation. The pricing range is between $25,000 and $40,000 and shipments will happen in Q4 2025 for music lovers who admire excellent sound quality.

Heritage of American Hi‑Fi

The history of Mark Levinson begins in the early 1970s, with the founder developing preamplifiers that improved the quality of audio. After over five decades in the industry, Pro-Ject is recognised for providing top-of-the-line products that preserve the richness and essence of live music from turntables to headphones. You can compare Mark Levinson to the Rolls Royce of hi fi: each product is finely built and beautifully engineered and the cost is exceptionally high.

Launch at HIGH END Munich 2025

It was at the HIGH END Munich show which happens every year in May, that the 600 Series made its debut in May 15, 2025. Consider the joy: numerous fans gathering at Atrium 4.1, Room E119, to be part of these innovative products being demonstrated. It went beyond a launch; Legacy Line marked a celebration of all things audio, covering both the past and future.

 Pure Path Circuit Architecture

Every 600 Series component is centered on the Pure Path circuit which is a completely discrete, dual mono design meant to keep the sound as perfect as it can. Mark Levinson achieves a clean separation between the left and right channels by putting each one on its own circuit board. It’s as if you had two powerful engines working together inside the system to produce clean audio.

Tectonic Industrial Design

The series’ design is striking and eye-catching. Made completely from solid aluminium, the chassis have glass panels and red lighting that appears through accents made from volcanic glass. According to Mark Levinson, this is what he describes as Tectonic design, referring to the strong power hidden underneath, like the earth’s molten core.

No. 626 Dual‑Mono Preamplifier

No. 626 is central to the functioning of every source. It is equipped with a 32 bit/384 kHz PCM DAC, native DSD DAC, high performance MM/MC phono stage and a quality Class A headphone amplifier.

Key Features:

  • Precision Link III DAC is the best choice for digital conversion.
  • An MM/MC card for passionate vinyl record listeners
  • A Class A amp specifically designed for audiophile headphones

Listen through your earphones, set up-side down speakers or stream your favourite music and the No. 626 delivers every detail clearly.

No. 632 Dual‑Mono Stereo Power Amplifier

If a dual mono setup is required, each channel delivers up to 300 W into an 8 Ω load; if a mono bridge is needed, the wattage doubles.

Highlights:

  • For excellent response, it operates in Class A/AB mode.
  • Toroidal power supplies are housed separately.
  • Achieving the best separation of the left and right channels

Getting a high quality speaker system and need power? The No. 632 easily powers even the most difficult audio transducers.

No. 631 Flagship Monoblock Amplifier

Those who want pure and powerful sound will be delighted by the No. 631 which disperses 600 W into a speaker with plenty of headroom left.

Standout Specs:

  • Designs that do not share any transistors
  • One channel is used to focus on producing laser sharp images.
  • Fine play and strong power are possible with Class A/AB topologies

Think of the sound rushing like a freight train through your speakers, leaving all details loud and clear.

Performance: Power, Precision, Purity

“Be it with complicated or soft sounds, the 600 Series always brings inspiring richness and elegance to your music,” according to HARMAN Luxury Audio. Put simply, if you play with full effects, the Engage still reproduces soft and gentle sounds with ease.

 Price and Availability

You need deep pockets: 626 costs $25,000, the 632 costs $30,000 and the 631 costs $40,000 all for monoblock speakers. According to Mark Levinson, the 600 Series will be shipped in Q4 2025, so audiophiles can anticipate it during the holiday season.
