• The Döhmann One Mk3 is engineered to deliver unparalleled performance in analog playback. It results from many years of research, development, collaboration, and listening by internationally acclaimed analog designer Mark Döhmann and his team. When a stylus moves through the grooves of a record, it converts vibrational energy into an electric signal. The shape and cut of the grooves contain an immense amount of information, and the objective of any quality analog music system is to interpret this information as accurately as possible. For that to happen, the stylus needs to operate in an environment free of any vibrational energy & resonance that is not a result of its interaction with the grooves. However, in practice, there is a lot of energy moving through a turntable system that the stylus picks up in addition to the vibrations associated with the grooves it is designed to do. This unwanted energy can be heard as distortion, smear, added harmonics, and channel imbalances, and these types of sonic phenomena often obscure the micro details within the recording and add coloration to the music. The first step in designing a high-quality turntable is to carefully measure where this unwanted energy comes from and how it moves through the system. At Döhmann Audio, we have spent a lot of time using sophisticated test equipment to measure the resonance profiles of standard turntable designs because to improve the performance of a turntable, you must first have an accurate understanding of where the resonance is generated and how it behaves. Our research indicated that some resonance originated from the mechanical systems of the turntable (e.g. motor, bearing, platter, etc.), some from the environment (e.g. building, floor, sound waves, etc.), and some from the electrical systems (e.g., power supplies, control circuitry, etc.). Furthermore, the turntable also acts as a physical ecosystem where resonance moves through the various parts and interacts with itself. We also made some ground-breaking discoveries about how the vinyl record interacts with these energies. From Edward: I benefitted from spending three full days with Mark Döhmann at Audio-Ultra as we rebuilt three tables into MKIII status, an education I was fortunate to receive.  Once we were done with the upgrades, now we were able to compare the Helix One and Helix two tables side by side so I could understand the differences. Mark simply unbolted the armboard with the tonearm attached and the balanced cable still seated into the CH Precision Phono amp and moved it over to the Helix 1. As soon as the needle dropped, it was evident from the crackle of the out groove inward to the music itself. The noise floor went from crazy low on the Helix 2 to even lower on the Helix 1, revealing even more clarity, detail, body, texture and all the audio superlatives used in our industry - it was beyond words. This was repeated on the last days listening event before a group that included two non audiophiles that all described their experience in a very similiar manner.  Note: The retail price for all Döhmann Turntables includes white glove setup and training to ensure customers receive every drop of performance these tables are capable of.
  • At the core of Döhmann Audio’s philosophy is the study of resonance energy in analog playback systems. In 2020, our R&D Lab acquired a new piece of test equipment that enabled us to measure resonance propagation and behaviour with a significantly higher accuracy and resolution than ever before. The period of research that followed resulted in some discoveries and insights that led to the development of the Mk3 technologies. The Mk3 Record Clamp is the result of extensive research, data analysis and resonance profile modelling. It represents a significant step forward in analog system design, incorporating new technologies that have never been used in audio applications before. It is difficult to imagine the difference a record clamp can make to the sonic presentation and performance of a turntable, however, the proof is in the listening. Without being aware of it, most of our sound quality reference moments have been experienced in the presence of record & spindle resonances. Remove them, and the paradigm shifts again. The Mk3 Record Clamp has been designed with three principles in mind:

    1st Principle – Record Resonance

    We have been aware that vibrations are present in the vinyl medium itself, both originating externally from sound waves in the air and from the mechanical systems in the record player. They also originate ‘internally’ from the interaction between the stylus and the record grooves. However, utilising the latest technology, we were able to not only measure this resonance, but also observe how it travels within the vinyl medium. This led to a critical thought process on how to attenuate these “self-chatter” resonances using a properly executed clamp design. To address the challenge of record-originating resonances, the new Dohmann Audio Mk3 Record Clamp has the following features:
    • Large mating (damping) contact surface area for the new clamp design to work as opposed to using high force contact points like a spike or ball bearing.
    • Metallurgy was specifically chosen for transmission purposes with internal chambers used for the critical damping materials. One material cannot provide the broad frequency spectrum needed – it needs to be a carefully selected group of materials.
    • Compact design to lower the profile and impact on bearing precession.

    2nd Principle – Spindle Resonance

    We measured resonances through the spindle (stem) which originate in the bearing. These frequencies need to be addressed by different tuned materials and the upper section of the clamp has its own purpose-designed chambers to allow addition of specialised polymers.

    3rd Principle – Isolation of the Record from the Spindle Resonance

    We realised that mitigating spindle resonance helped, but in order to achieve the best sonic results, we had to keep those resonances completely away from the record. To achieve this, a third constrained layer ring system is used to separate the upper and lower chambers which under clamping pressure creates a dissipation plate (Finite Element Method) that is shaped carefully to provide an optimum boundary interface. The cumulative outcome from addressing these challenges is a discernible improvement in clarity, resolution, focus, dynamic contrasts and tonality within the sonic presentation of a turntable. Although this record clamp was designed as part of the Döhmann Audio Mk3 project, it has been consistently demonstrated that this product will improve the sound quality of any turntable that it is used in conjunction with. This clamp design is a result of close collaboration within the team working at Döhmann Audio and our tight relationships with engineering and materials science leaders in our university and defence/industrial sectors. Without advanced knowledge of new materials and customisation capabilities, such breakthroughs would not be possible. We hope that the new Mk3 record clamp assists you to enjoy your vinyl music collection with greater emotional connection – The Döhmann Audio Team.

From Edward: I benefitted from spending three days with Mark Döhmann at Audio-Ultra as we rebuilt three tables into MKIII status. What I learned was how effective the Döhmann design is. As we added the series of updates one at a time, we would then make the table operable and repeatedly listen to the same record through each change.  At every, with the word, "every" being an absolute term, it was apparent the noise floor moved lower and lower, revealing more clarity where dynamics became more explosive, and the texture of the overall body was beyond words.  Note: The retail price for all Döhmann Turntables includes white glove setup and training to ensure customers receive every drop of performance these tables are capable of.
