EMM Labs EMM Labs DS-EQ1 V2 Optical Equalizer
When Ed made the decision to dust off his extensive vinyl collection, he was interested in finding out what the current state of vinyl playback was. During his research, he became intrigued withDS Audio’s optical cartridge technologyand their customers' experiences.
Initiating a collaboration with Tetsuaki Aoyagi, head of DS Audio, Ed purchased the W2 optical cartridge for development and was impressed during his preliminary listening experiences. Compared to his reference MC cartridge, the W2 exhibited improved resolution, clarity and low frequency response. This motivated Ed to dive back into the world of vinyl playback, resulting in the first EMM Labs optical equalizer, the DS-EQ1, designed exclusively for interfacing with DS Audio optical cartridges.
Upon receiving the full line of DS Audio cartridges, Ed immediately recognized a common sonic signature within the line, increasing in its degree of refinement and depth from the entry-level E1 to the flagship Master1 cartridge.
The DS-EQ1 V2 is designed with an obsessive desire to lower noise and distortion, and to extract every bit of detail and information from any DS Audio optical cartridge. The DS-EQ1’s circuits are all Meitner designed in-house, including its power supply, and are optimized for short and direct audio paths. EMM uses a custom made ceramic PCB for the equalization and amplification stages, which allow for the superior extraction of low level details in the audio.
From its proprietary equalization, class A amplification, and power supply systems, to its touch panel buttons and sophisticated aluminium chassis, the DS-EQ1 is the ultimate partner to any DS Audio optical cartridge.
The V2 was released on December 1, 2024 and is now available at your local dealer and online.
“I found developing the DS-EQ1 both extremely interesting and highly satisfying. It was an honour to work on this project in close collaboration with DS Audio. I now find myself improving and appreciating my vinyl collection on a daily basis with DS Audio optical cartridges and the EMM Labs DS-EQ1 optical equalizer.”, -- Ed Meitner
What Customers Have to Say
"When I heard about a V2 upgrade for the DS-EQ1, I found it hard to imagine how it could be better. Well, I'm here to tell you that V2 is not just an incremental upgrade, it is a giant leap forward in terms of musicality and listening enjoyment. All of the strong points of V1 are retained, but now everything just sounds more like real music. Every voice and instrument now has a layered sound quality that adds richness, color, and believability to the experience".

EMM Labs DS-EQ1 V2 Optical Equalizer
The EMM Labs DS-EQ1 V2 is a purpose-built optical phono equalizer that elevates DS Audio cartridges with astonishing microdetail, coherent imaging and controlled low-end authority. Reviewers credit the DS-EQ1 with superb clarity across bass, midrange and treble, revealing layered textures and precise transient slam while keeping a refined, musical presentation. Its fully discrete, class-A topology and meticulous power-supply design yield exceptional dynamics and soundstage depth, making complex recordings feel immediate and tangible. The heavy, milled, bead-blasted chassis and precise controls underline its high-end build. Ideal for serious vinyl enthusiasts running DS Audio optical cartridges who want forensic detail without harshness, the DS-EQ1 is positioned as a reference-level component—one that reviewers such as Jason Thorpe and Audiophilepure argue justifies its premium.
Pros
- Extraordinary resolution and texture retrieval that uncovers previously hidden detail in records, improving instrumental timbre and focus.
- Powerful, well-controlled low end with deep extension and articulate slam, delivering weight without bloom.
- Exceptional imaging and soundstage cohesion—front-to-back placement and transient definition are consistently refined.
- Premium mechanical build and quiet operation: a dense, milled chassis with attention to vibration control and precise controls.

Cons
- High price point — the unit’s premium cost may be hard to justify for some systems, especially if you’re single-ended rather than balanced.
- Highly specialized design: intended for DS Audio optical cartridges only (no MM/MC support) and lacks traditional loading adjustments—limits broad cartridge compatibility.
Transparency
89/100
Reviewers repeatedly praise the DS-EQ1's ability to extract microdetail and present a very coherent, controlled signal (SoundStage: 'massaging, purifying, and controlling the signal'; Audiophilepure: improvements in top end and bass), and no review reports audible hum or hiss. However, neither review uses explicit phrases such as 'dead quiet', 'black background', or 'vanishingly low noise floor', so while evidence points to excellent transparency, the score is restrained below the 90+ reference band.
Sound Quality
92/100
Reviewers emphasize strong transient drive and low-end impact: SoundStage describes being 'clobbered by the deep, drop-down bass' and a lively, organized presentation, while Audiophilepure notes improvements in bass weight and articulation. The DS-EQ1 is repeatedly described as bringing records to life with punch and nuance.
Cartridge Compatibility
76/100
The DS-EQ1 is specifically designed for optical DS Audio cartridges: the RCA input also supplies power to the cartridge's LEDs and reviewers note there is no need for impedance or capacitance adjustability. That specialization yields excellent performance with the intended optical cartridges but limits general MM/MC compatibility and user-adjustable loading, so the score reflects strong performance but narrow applicability.
Build Quality
94/100
SoundStage details a heavy, dense 26-lb chassis, milled and bead-blasted aluminum panels, precise fit and 'military precision' controls; Audiophilepure corroborates that it 'surpasses the DS 003.' The construction and finish are described as reassuringly high-end and robust.
Value for Money
90/100
At roughly $12.5k–$13.4k reviewers note the price is high ('twelve-and-a-half grand for a silver box') but both explicitly state the premium is justified by the performance—SoundStage: 'there’s no question... the nine large above the cost of the DS 003... is more than just justified'; Audiophilepure conveys similar endorsement. The sentiment is 'premium but warranted,' placing it in the 'justified premium' tier.
