  • 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.

  • The all-new TIDAL Piano G3 - Absolute Entry. Improving classic designs does not mean changing them. Rather, it means improving details while strictly continuing and following the unique concepts of the original. After building the TIDAL Piano for over two decades, the third generation of our worldwide praised Piano models - the Piano G3 remains a classic. Continuing the TIDAL loudspeaker par excellence, the Piano G3 has all the core elements of our philosophy. It embodies even more than what TIDAL stands for ultimate masterpieces with the highest complexity hidden behind the most sophisticated simplicity. The Piano has always been a very special loudspeaker for TIDAL. A major part of the company and its history includes this model, which paved the way for what came later. Many things have been written about the predecessor Piano G2, yet the 2022 all-new Piano G3 model moves the limits of this concept even further. The TIDAL Piano G3 is built like nothing else and was never designed for size or dimensions. It masters the trick of being an ‘entry’ masterpiece into our collection and yet is an 'ultimate choice' simultaneously. An incomparable classic.
  • The TIDAL Audio Contriva loudspeaker continues the story of its predecessor after a decade in production with worldwide praise and awards. The Contriva G3 has new exclusive drivers (diaphragms of diamond black ceramic and carbon-fiber aluminum) and a cabinet made of TIDAL’s TIRALIT cabinet technology. Not a single part has been untouched to elevate product quality and take the sonic performance to a new level.
  • Tiralit™ Ultra Cabinet

    The cabinet of the TIDAL Akira is made out of TIDAL's proprietary cabinet material, TIRALIT™. This cabinet material combines the rigidity of hard materials such as metal with the resonance absorbing behavior of softer materials such as wooden materials like MDF.

    Diamond Tweeter

    The TIDAL Akira uses the same diamond tweeter technology as the big La Assoluta, it is a 1-carat pure diamond diaphragm tweeter with 30mm diameter (1.2"). Not only is it the biggest diamond tweeter in the world, TIDAL was also the very first company to use a 30mm diamond tweeter. 

    Diamond Midrange Woofer

    TIDAL's exclusive 80 mm midrange woofer is the result of the Accuton TIDAL cooperation and is to be found only in TIDAL speakers, Akira and La Assoluta. The diaphragm itself is made out of pure diamond.  Aside of the unique motor- and basket design, its unique 80 mm diamond diaphragm has the perfect diameter to be small enough to have an amazing off-axis dispersion and low moving mass for excellent impulse response

    BCS Woofer

    Another specialty only found in this speaker is the BCS woofer of the TIDAL Akira. The drivers were designed to play within the bass chamber with its big inner volume to play extremely deep, fast, and without compression, at the lowest and highest reproduction levels.

    BCS Radiators

    The TIDAL Akira is designed to play ultra-precisely, even at the deepest frequencies. Each Akira is equipped at the backside with five long excursion passive radiators to support the front-firing woofers with a very deep and low distortion reproduction of bass frequencies without any movement noise.

    Passive Crossover

    Mounted in a hermetically shielded chamber are pure copper foil capacitors, coils of the same caliber, and silver-carbon resistors - only the finest components with proven long-time stability are used for our crossovers.

    Silver Terminal

    The Akira includes Tidals pure silver binding posts. The complex construction is of a fiber-reinforced polymeric material that avoids any inductive electromagnetic field.
  • La Assoluta from Tidal Audio represents the pinnacle of achievement in loudspeaker design. The La Assoluta is a four-way, 7-driver loudspeaker that towers over 7' - 5" tall, with each loudspeaker weighing 1069 lbs.  This 93db efficient, made-to-order marvel is a shear statement in both presence and performance due in part to its massive size that houses the largest diamond diaphragms tuned to offer a performance so astonishing that it simply has to be heard.   Attached to the front baffle is a patented double-driver array around the tweeter that utilizes 27 carats of industrial-grade diamonds per speaker, reproducing flawless frequencies up from 150 Hz. The proprietary crossover only uses the best in hand-selected and matched materials that, like all Tidal speakers, are housed in a hermetically sealed chamber.  Resonance is controlled with Tidal's TIRALIT-Ultra advanced cabinet material and bracing, which also supports Tidal's famous lacquered piano finish or the option of world-class veneer finishes that can be selected by the owner to fit any decor. For further performance, The La Assoluta also allows passive plug-and-play performance and can be tuned even further with active bass activation using the Assoluta-LPX. If you can envision this loudspeaker in your setting, then we cordially invite you to see and hear this loudspeaker firsthand within the factory listening room in Hürth, Germany.
  • The TIDAL Prisma. Transparency and invisibility at a new level. The Prisma does exactly two things only, and it does it in absolute perfection: selecting the source and adjusting the volume. It has to be experienced to understand the game-changing way it does this. It takes itself acoustically completely out of the way between the source and the power amplifier. The unique concept, the TIDAL pre-amplifier topology itself, and the execution of the complex multilayer PCB board are the inner heart of the unique performance. On top of all that the Prisma comes with our legendary fully balanced MC phono input. A line stage like no other, as always embedded into our timeless and iconic TIDAL cabinet and built-in perfection.
  • The TIDAL Intra results from the uncompromising implementation of our most basic requirement: pure amplification of the musical signal without adding any sonic color or concealing even the smallest details.  With it, we offered TIDAL amplification in the same cabinet size such as the Prisma and Camira. What might look at a first view as a multi-channel purpose amplifier - is more than that. The TIDAL Intra is first and above all a high-end stereo power amplifier. It contains two physically divided stereo modules, built like a dual mono power amplifier. For true stereo power amplification, one channel per module per speaker side. Then each main power supply for each module takes care of only one channel - for ultimate 2-channel sound. The options on top of that are built inside already: one could also connect with two channels per speaker for passive or active bi-amping. Or one does integrate the TIDAL Intra into a high-end multi-channel system. Intra can also be bridged for subwoofer applications with the TIDAL LPX technology.  The Intra offers true stereo excellence!
  • We have pushed the concept of the Impulse stereo power amplifier to its extreme and developed an all-new 1.600 VA power supply with true power regulation. Thus, the TIDAL Ferios mono amplifier board is certain for all practical means and purposes to be supplied with never-failing power reserves and a lavish feed of clean current that will easily drive every imaginable speaker. The generous supply of additional power is merely a welcome byproduct. The real goal was the absolute relaxation with which the Ferios performs, to the extent where any attempted description of sound attributes becomes meaningless. The Ferios is quite simply a benchmark for amplification in this size.
  • The TIDAL statement power amplifier in monoblock fashion. The Assoluta is the finest we offer to amplify the most delicate music signals to ultimate power. The Monoblock offers all the loudspeaker's grip and control without adding color to the signal.  The result we have accomplished is beyond the trial to get an idea out of the provided specifications, data, and used technologies. Silence. Finesse. Endless control. Music in its true beauty.
  • The TIDAL Arkas is designed to be the perfect digital music content controller for TIDAL's high-end systems. The Arkas approach was simple: build the perfect musical data file transport with TIDAL performance and reliability. In general, the TIDAL Arkas concept can be compared to the build of a super sports car: as little weight as possible, by removing all but what is necessary, combined with the most power possible - to get the best performance and keep up with the pace. Arkas is built as a no-file-storage system internally and only the core relevant technology around an extremely potent power supply, and it is combined with a unique file transport output. All digital half-life components like music data storage, NAS/music server systems, and hard drives, are intended to be outside the TIDAL Arkas. This way the TIDAL Arkas remains the center of content management as an elite streamer for many years, since some things will not change as quickly as digital technology: our timeless TIDAL electronics cabinet and the power supply inside the Arkas are future-ready. The peripheral components to run the PCB boards and the streaming PCB itself are designed to be upgraded and adjusted - protecting your investment and guaranteeing the very best sound for your TIDAL systems. Whatever the future brings, the Arkas is prepared. Every Arkas comes with a proprietary data connection output called TIDAL-Link. This unique cable connection overcomes the disadvantages of SPDIF RCA, AES, or USB in sound quality and the lack of possibility of playing certain files with certain connections. The TIDAL link cable comes with every Arkas, ready to be plugged into the TIDAL Camira to unleash its real performance and create the perfect TIDAL combination.
