Edmund (Ed) Manfred Meitner's name and reputation have long been synonymous with pioneering fields of digital audio, especially DSD. In 1971, after designing the first fully automated studio console, Ed identified what he calls "the jitter problem." He worked with Sony and Philips to help create and refine SACD and subsequently designed the first complete six-channel DSD playback system for home use.
In 1998, while developing the eight-channel A/D and D/A DSD converters still used to create most SACDs, Ed founded EMM Labs¹ and became head of design, with the goal of bringing DSD to the consumer realm. Far more recently, he designed the EMM Labs DS-EQ1 and Meitner DS-EO2 optical equalizers, which are sanctioned by DS Audio for use with their optical cartridges.
Less widely discussed are Ed's amplifier circuit designs, which are the heart of the EMM Labs MTRX and MTRS amplifiers he designed collaboratively with Mariusz Pawlicki, EMM manager of R&D, and the late Zenon "Zanny" Muzyka. Mariusz helped develop the operating scheme for the amplifiers, the "smarts" in the amplifiers' monitoring and protection schemes, and their new "hybrid" power supplies. (More on this below.) He is also actively involved in quality control (QC) and measures every amplifier that leaves EMM Labs. Zanny, who passed before completion of EMM's latest amplifier designs, contributed to their industrial design and power supply.
EMM Labs' history producing amplifiers dates back to 2012, when it released the original 1500W class-AB MTRX mono amplifier ($130,000/pair). The company has since released various upgrades, including those to the driver/input stage. In 2015, EMM released the 1000W MTRX2. Most recently, in November 2023, EMM announced its successor, the 1000W MTRX2 V2 monoblock ($115,000/pair), as well as the MTRS ($65,000), the company's first-ever stereo, class-AB power amplifier and the subject of this review.

Buckeye PURIFI EIGENTAKT 1ET9040BA1
Back in 2016,' I documented the rise of class-D amps using the early Tripath technology. Used in the Bel Canto eVo 200.2, TriPath cracked open the door to the High End but was never admitted due to a dim and opaque treble.

Gryphon Audio Designs Diablo 333
What's in a name? Denmark-based Gryphon Audio Designs laid down a marker when company founder Flemming Rasmussen chose that name in 1985. Browsing through the current Stereophile Recommended Components list, I only found one other manufacturer that utilizes an animal moniker.
The Rega Naia Turntable. Add Lightness.
To watch as Rega very slowly expands its turntable offerings upmarket requires the patience of a Thomas Pynchon addict waiting for each new tome from the notoriously slow-working and reclusive author.

Record Player Revelations
Like romance or car racing, the act of playing records is tactile by design. Like drifting through curves or making out, spinning vinyl is a learned skill that requires users to touch everything with practiced assurance.
Taking Care of Business
As Jim Austin wrote in this space in the December 2024 issue, following a medical procedure that he had in mid-October, he needed to take several weeks' leave to recuperate. He delegated the magazine's production to Managing Editor Mark Henninger, AVTech Editorial Director Paul Miller, and myself. The three of us worked with copy editor Linda Felaco and longtime art director Jeremy Moyler to produce the issue you hold in your hands.
