There’s something about Australian ‘mate’ culture that permeates audio turntable designers from the continent. Mark Döhmann of Döhmann Audio is a perfect example. The maker of the Döhmann Audio Helix One Mk3 could easily be an egomaniac. But he isn’t. He’s the kind of disarming expert who is confident in their designs and fascinated by the designs of others. He’s not the kind of guy who will tear down a rival. Instead, he’s fascinated by why people make engineering decisions and how they positively shape products.
Döhmann has also made his own design decisions and can explain the concepts and their reason for inclusion. However, it never feels like he’s fighting his corner or making bold claims. The late Max Townshend was cut from the same cloth. This excited interest is why Mark Döhmann can list dozens of similarly excited audiophiles. Audiophiles who are top-class turntable, tonearm, and cartridge makers. They consider him a force for good and a friend rather than a rival.
Of course, his kudos among his peers would dip sharply if the product he made wasn’t up to scratch. Still, Melbourne-based Döhmann Audio has been producing world-class turntables under its own steam since 2015. For several years before that, Mark had been a key figure in the production of high-end turntables. His design smarts contributed to one of the most respected high-end turntables of this century, the Continuum Caliburn.
No flash in the pan
The original Helix One was Döhmann’s first commercial design. The more affordable Helix Two followed in 2017, a couple of years later. This helped demonstrate that the company was no flash in the pan. It also allows Mark Döhmann more leeway in honing these two designs to perfection.
It’s worth winding the clock back and looking at the Helix concept’s original and Mk2 versions. The move from Helix One to Helix One Mk2 created a virtually new turntable. It upgraded and simplified every subsystem along the way. This is especially true in the case of the floating arm suspension system. You could argue that the changes from Mk2 to Mk3 are more ‘evolution’ than ‘revolution’. You’d be an idiot, though. It has a new composite bearing, DC power supply, drive, resonance control system, composite armboards, record clamp and an improved platter. That’s more than just ‘evolution.’
Retrofittable
You can take any Helix One and upgrade it to the latest spec. It might be ‘spendy’ because there are so many changes over the years, but it’s possible. The fact that these changes are retrofittable is a testament to Döhmann’s respect for its owner base. It’s also a sign of the quality of that original platform.

A key part of the Döhmann Audio Helix One Mk3 design is the MinusK negative stiffness isolation base. This, drawn from the world of electron microscopy, provides isolation at 0.5 Hz vertically and 1.5 Hz horizontally. That is far outside the bandwidth of LP replay. Mark Döhmann handles the Australian distribution of MinusK in the audio and professional fields. But if you are thinking that the Helix One rests on a MinusK, think again. That’s not how Döhmann works. The turntable exists in a symbiotic relationship with a custom version of the Minus K.
MinusK
Using the MinusK falls in line with Döhmann Audio’s core principles. Any turntable must be a supremely accurate vibration-measuring machine. It converts vibrational energy, from the shape and cut of the grooves, into an electrical signal. In an ideal world, the turntable would retrieve and convert that vibrational energy and nothing more. The sound would be unadulterated by the surroundings or the mechanical shortcomings of the turntable, arm, and cartridge.
Sadly, that ideal world is not the real one. A vinyl replay system introduces a lot of unwanted energy at the source. We’re not dropping great revelations here. This reduction in unwanted energy has been a goal in turntable design for over 130 years. However, Döhmann dedicates considerable time to researching the unwanted distortions introduced by the front-end. Mark Döhmann quickly found that resonance was the problem. Resonance is three problems wrapped into one. The mechanical aspects of a turntable introduce a resonance. Then, there is resonance from the environment, such as footfall. Finally, some is coming from the electrical subsystems in a turntable (such as power supplies for a turntable motor).
Moving resonances
In the process, Döhmann found that these resonances constantly move through the turntable itself, creating its own internal resonance artefacts along the way. And in trying to eliminate their impact on the music itself, Döhmann inevitably looked toward platforms designed to keep extremely sensitive equipment stable, which led to MinusK.
That engineering also includes a “mechanical crossover” that creates a ‘least harm’ mechanical pathway to dissipate vibrations above 100Hz. This works by mounting the motor, bearing, and armboards on interlocking plates to reduce unwanted vibration impacting the stylus/record interface.
However, nothing was off the table, and that included getting in touch with NASA engineers to discuss mechanical isolation in satellites or mining engineers to talk about taking sensitive equipment down mines was all fair game. That resulted in some serious left-field ideas to crack the vinyl nut.

Many of these revelations hit pay-dirt between the original Helix One and the Helix One Mk2. This saw even deeper integration of the Minus K vibration isolation system utilising what the company calls ‘NSM’ technology, fully floating armboards, a custom-designed Swiss-manufactured motor designed to Döhmann Audio’s specifications and carefully designed resonance dissipation pathways within the chassis. Döhmann Audio’s PowerBase contains the power supply, with control software to drive the new motor and special high-frequency and radio frequency absorption features. It also contains a suspension stabiliser to lock the table from moving during record changeover, a lighting control system and power filtration functions.
That button…
Looking at the front of the PowerBase from Helix One Mk2 onwards, there is a large, circular push-button. It’s even more noticeable because it contrasts both colour schemes of the Helix One Mk3. Press it, and… it does nothing. At least, at the moment, it does nothing. A big part of the promise of the Döhmann design is its flexibility and upgradability. That button will operate a vacuum record hold-down at one point in the future. Mark Döhmann promises that all the vacuum ‘gubbins’ (save for the external pump/compressor) will fit inside the ample Helix One Mk3 footprint.
The turntable’s size has an added and obvious bonus, multiple arms. The Helix One Mk3 and its extremely clever floating arm bases are designed to work with two arms, whether for stereo or mono use or to get the sonic benefit of multiple arm and cartridge combinations. This is so intrinsic a part of the Helix One genetic make-up that if you are a ‘unidexter’ (borrowing the term from Peter Cook’s famous ‘One Leg Too Few’ sketch), you should probably be looking at the smaller Helix Two Mk3. This incorporates the technologies rolled into the Helix One Mk3, but in a smaller, single-tonearm footprint, saving you almost £19,000. However, we went for maximum chonk in the Helix One Mk3, despite using it primarily with the one tonearm – the excellent Reed 5A tested in Issue 219.
Look ma, no belt?
Maybe the least prominent part of the Döhmann Audio Helix One Mk3 is that it’s a belt drive. Döhmann thinks that, though good, the limitations in a direct drive are noticeable enough for belt drive to still reign supreme from an audio perspective. The platter housing hides the belt. The end-user can change it, but I think this should be considered part of a periodic service. That’s not a suggestion directed at the Döhmann deck alone. If you have a significant investment in a complex piece of engineering, regular (maybe bi-annual) maintenance is a good idea. Over the years, I’ve heard a few potentially excellent decks in dire need of service.
The platter-and-bearing system draws on the 15kg triple-sandwich non-ferrous alloy/thermoplastic platter topped with a permanently attached damping mat. However, this, too, has undergone significant changes, including adding a new ‘Advanced Composite’ bearing with a single ceramic ball and a thrust pad designed to place the rotation point within the centre of the platter itself. A dual-groove, machined-aluminium pulley drives the platter. This uses a pair of dissimilar-diameter O-rings, each with a different hardness grade.

This speaks to Döhmann Audio’s engineering concepts, best summed up as ‘build it to last’. The powerfully built platter, platter housing, motor and its housing, and power supply module are all testaments to that. That power supply module is the size of a small power amp. Just visible from the front, this is – almost – hidden from view.
No compromise
How little Döhmann Audio is prepared to compromise extends to the motor. It’s a custom-designed, Swiss-manufactured, high-torque design controlled by a custom, software-based, closed-loop servo control system that monitors and calibrates speed more than 130,000 times per second. Turntable brands tend to buy off-the-shelf motors and often deploy surprisingly simple means of speed control (such as having a line or two cuts into the inside of the platter, which is read by an optoelectronic circuit to adjust speed once or twice per platter revolution).
That Döhmann Audio goes for the road less travelled shows how seriously the company takes its vinyl replay. This is probably a good idea for a company that only makes turntables!
Masterwork
This all spells a masterwork of a turntable and the kind of device that should be the stuff of professional installation. With an all-up weight of 76kg, it’s not a 10-minute installation project anyway, and in fairness, the Döhmann Audio Helix One Mk3 is not the kind of turntable that is in any way prone to drift or sag; when it’s set, it stays set. You need someone exceptionally well-versed in making it ‘set’ properly.
This is why I think the nearest most people get to the sophisticated engineering of the Helix One Mk3 will be when they press the two buttons on the carbon-fibre top plate, backed up by a rear-panel–mounted speed-adjustment feature, which can be adjusted and diagnosed over the Internet. The top-plate buttons control operation and speed and pressing them shows how free-floating the Helix One Mk3 can be. This is an almost unnerving experience, even for those used to turntable design. This high-mass platter is set in a heavy chassis; you don’t expect those to move around. You don’t expect them to dance with the freedom of movement you might expect from something like an old but well-maintained Pink Triangle. Because it has the freedom of movement and the authority of sheer mass, your first time cueing up a record comes as a bit of a shock.
Passing albums
And then you listen to it. An album passed, played front to back. the listening notes don’t even go as far as listing the album or track, just some shorthand that reads ‘listener hypnotised by sound. Try again later.’ I’ve never played quite so many records and made so few notes because each time I played a record, I was absorbed by the music that to write anything about what I was hearing was an act of musical heresy. I didn’t want to pollute my music by breaking the spell and writing something down.
After several warm-up albums, I felt sufficiently ‘dunked’ in sound to start to make some observations. The first of which is, for so heavy a turntable, it has a very light touch, but not too light, just relative to what you might expect from a large and weighty design.
The sound is full of grip and drive, with none of the over-refinement from high-mass turntables nor the steely sound you can sometimes get from suspended designs. It’s just… damn good.
Sheer musical excellence
While there are differences you can point to in sound between extreme high-end decks, they mainly converge on a point of sheer musical excellence. So, if I say the sound of the Air Force One is ‘smoother’ it’s not like the Air Force One is satiny sounding throughout or that the Döhmann Audio Helix One Mk3 is more rough-hewn. These are nuanced differences, akin to adding or subtracting a couple of contrast steps to your TV set’s picture. That this turntable trades blows with the established vinylista best-in-breed shows just how good the Helix One Mk3 gets.
The Helix One Mk3 has its accent, but it’s a mild one. The language it speaks is absolute fidelity to the groove; if it were more faithful to that goal, you’d find it burning digits at the stake. The turntable has fewer points of omission or emphasis than most turntables, and this is all too clear to the listener when they play a record on their existing deck; I listened to ‘Canadee-i-o’ by Nic Jones [Penguin Eggs, Topic] and you would expect the relatively simple combination of acoustic guitar and male folk vocals to be fairly free from exaggerations or absences. Still, that total sense of ‘thereness’ the Helix One Mk3 bestowed on the music wasn’t as present on other top-end decks I’ve tried over the years. And the more records I played, the more that distance was confirmed.
Quicksilver
However, I mentioned that mild accent, and it’s one of quicksilver leading edges and dynamic range as opposed to a more ‘beauteous’ approach to the musical presentation. This worked remarkably well with various musical styles, from the unrelenting Stravinsky-based assault on a piano by Alexander Toradze [EMI] to the twisted beats and electronic percussion sounds of Orbital [‘Are You Alive?’ Optical Delusion, London], the speed and precision of beat information are paramount… and often a point where super-decks fail to shine. I’ve erroneously attributed this to the sheer amount of information being processed in our heads.
Still, the Helix One Mk3 shows it’s just a form of distortion and a turntable can deliver all the detail and do it fast. In both these recordings, the speed of attack dictates the recording, and any flatness or slowing of the sound is simply a mistake. Granted, there are audiophile arguments about whether Orbital should be included in a review of high-end equipment, but if a high-end deck cannot play everything as well as possible, arguably it doesn’t deserve the high-end epithet. Döhmann Audio’s Helix One Mk3 plays both albums with excellent speed and precision. That doesn’t just form the basis of ‘Pace, Rhythm and Timing’ but points back to the ‘you are in the listening room’ concept at a deep level.
Audiophile-friendly
Naturally, when the turntable is fed something more audiophile-friendly – ‘Do Nothin’ Till You Hear from Me’ from This One’s For Blanton!, by Duke Ellington and Ray Brown [Pablo] – the sound is astounding. The instruments are in front of you, with a believable dynamic range. It also has the sort of detail that makes you feel as though you’ve stepped back 50 years. This is an overplayed recording at high-end audio shows for a reason. However, heard through the Döhmann, it’s like hearing it anew for the first time. Wow!
An example of what this deck does so well is ‘The Ghost’ by Alice B Savage [in|FLUX, City Slang]. Her small, yet powerful voice, sings “Stop haunting me, please” in the chorus. She sings about an ex-partner who sounds suspiciously like a stalker. It is chillingly beautiful and stops you in your tracks in a way many decks purport to do. But the Helix One Mk3 does! That voice stands both apart from and integrated into the rest of the music.
If that sounds impossible, it usually is. The skills of the Döhmann Audio Helix One Mk3 to extract and resolve that aural dichotomy in one. And that is what sets the turntable apart from others. This musical Mise-en-scène is something that, once heard, is never forgotten. It is also surprisingly prevalent in the best recordings. Unfortunately, we often equate it with ‘image separation’. Sounds are artificially spaced out instead of cohering within a musical whole. The Döhmann shows us an alternative view!
Don’t stop believin’
Some years ago, I believed we had reached the limits of what could be pulled from a groove. I was very wrong. What never ceases to amaze me about vinyl is how much more we can extract from records made decades ago. The level of information extraction possible from the Döhmann Audio Helix One Mk3 – and the handful of super-decks that form its very select peer group – was almost impossible to achieve 10 years ago and completely unattainable at the turn of the century. Information hidden in grooves cut as Sputnik was bleeping its way around the planet. How much more is still locked away, waiting for the next generation of vinyl replay systems?
The Döhmann Audio Helix One Mk3 arrives fully formed at the spearhead of the best in vinyl replay. It’s so much more than the spiritual heir to the Continuum Caliburn. This turntable gives an insight into the recording that’s nothing short of jaw-dropping. It’s a platform that deserves the best arms and cartridges – preferably two of each. It also demands the finest phono stages known to humanity. In return, you get a level of sound quality previously only open to those in the studio control room when recording. It hints at still more from its vacuum hold-down platter when it arrives. That makes it a strong contender for the very best in LP replay today. It really is that good!
