The Worlds Best Turntables 2018?

Announced briefly late last year, TechDAS are following the 2017 release of Air Force One Premium, with premium versions of both Air Force Two and Air Force Three. 

TechDAS Who?

Whilst now a well established company in its own right following its launch of the TechDAS Air Force One in 2013, taking the high end audio world by storm, TechDAS cemented themselves at the forefront of turntable technology, design and manufacturing. Their first class build, performance and innovative features does also have a strong heritage proceeding it.

TechDAS designer Hideaki Nisikawa-san was a product designer and technical manager at none other than the famed Micro-Seiki of Japan who were responsible for manufacturing amazing quality and state of the turntables from the mid 70's up until their last unit shipped in 2001. With an almost cult like following many Micro-Seiki models are still highly regarded in the audio world today. The collectable flagship models still fetching very high prices when seen (rarely) on the used market. After the closure of turntable production at Micro Seiki, Nishikawa-san, still involved with analogue audio, bided time until the technologies for better implementing features like the innovative air bearing, and vacuum hold down had matured to the point he was happy to accept the challenge put to him by TechDAS parent company Stella Inc. of creating simply the best reasonably sized turntable in the world. In late 2013 he completed just that with the release of Air Force One. 2018 looks to be another very exciting landmark year for TechDAS.

Amongst the second to none build quality, outstanding technical and aesthetic design and stellar ergonomic usability are TechDAS's unique core underpinning technologies.

  • All TechDAS Turntables use an Air Bearing system. The foundations for this sophisticated technology are housed in a seperate box containing the audio quality PSU's, silent air pump & compressor, condenser and regulators. This isolated and extremely well regulated piped air supply connects to the rear of the turntable chassis and floats the weight of the heavy rotating platter on a tiny pocket of air. The advantage of this is to effectively eliminate the bearing noise, one of the largest remaining potential sources of noise in high end turntables. This also facilitates the use of the very high mass platters on TechDAS Turntables.
  • All TechDAS Turntables also implement an air fed vacuum system integrated into the surface of the platter. The record is placed on the platter where soft rubber inner and outer seals couple to the underside of the record, a press of the suction button on the turntable then creates an airtight seal and sucks the record firmly onto the platter. This has the effect of drastically reducing any playback caused vibration or resonance within the record from the stylus contact, whilst also firmly locking the record in place in a perfectly flat position. Slightly warped or bent records are no longer and issue and firmly held flat for playback. This has the effect of further and significantly lowering the noise-floor, creating blacker backrounds, more audible detail retrieval and an exceptionally spacious and lifelike soundstage.

Air Force Premium, What?

Both "Premium" version upgrades are far more significant than some simple cosmetic changes, and signal TechDAS's continuing pursuits in state of the art vinyl replay. These Premium editions clearly include very welcomed trickle down technology from the Air Force One Premium and their continuing R&D work for the quietly discussed, yet to come Air Force Zero (projected pricing ~$400,000.00AUD)

New features and Improvements are listed within the attached press release but to detail what we know exactly regarding the AF2 Premium and AF3 Premium so far.

A brand new upgraded single box power supply unit, this time containing a large capacity air condenser very similar to that of Air Force One Premium. The condenser allowing for better regulation and isolation from any potential fluctuations in pressure or flow in the air streams. Both Air Force Two Premium and Air Force Three Premium gain the dual air pumps design from Air Force One Premium, meaning completely seperate pumps running one pump for the Air Bearing and one for the Vacuum hold down.

Both models gain revised and extremely heavy new platters designed and created from a gunmetal material and a new material for the top inlay. These platters are hugely increased in mass from the already heavy platters on the regular Air Force versions. At 34kg for AF2 Premium and 29kg for AF3 premium, these platters will have extremely high rotational energy for even further improved speed stability. For reference sake that is twice the weight of competing flagship products from other manufacturers like Kronos Pro & Dohmann Helix and substantially heavier than the monster on the Kuzma Stabi XL. Further improvements to the air bearing allows the use of these extremely heavy platters which would be completely impractical on a regular mechanical bearing.

The suspension system has also been tweaked and improved to accommodate the much heavier platters. All these improvements, many directly taken or derived from improvements made to Air Force One Premium, will undoubtedly take these TechDAS turntables even higher in performance and closer than ever to the music.

Hear it, WHERE?

Sonic Purity retail showroom and store in Moorabbin, Melbourne is a constantly evolving space for high end audio and music. Sharing the experience with discerning customers on a daily basis of what is achievable in 2018 for the best sound for their home, apartment or studio is why we love what we do. We welcome visitors local and interstate to make a time to see, hear and touch our exclusive product range.

Many people have never heard vinyl sound as detailed and resolute, as immediate and present or with the type of authentic musical timbre and energy which we coax out of every turntable system we supply. The question often beckons, will I hear the difference? Is vinyl really that much better? Well as always that is for the listener to decide, but the process of listening, learning an appreciating the qualities of good sound, can not be done without first hearing a range of well put together and setup systems. Our showroom is just the place to do that. TechDAS is always featured in Sonic Purity Showroom, alongside our other premium turntables from Kuzma, SME, Thales & Dr. Feickert.


Air Force Two & Three Premium are due to arrive sometime in February. We always have TechDAS in stock to demonstrate and regular Air Force One, Two and Three will remain in the TechDAS Lineup and are all brilliant performers in their own right.  A launch Event will be held when the new premium models arrive for new and existing customers and vinylphiles to have an aural taste of truly otherworldly vinyl replay available from the Air Force Turntables. Please sign up to our newsletter should you wish to be notified, or simply make a booking to come and hear a TechDAS turntable today.


*MUNICH NEWS* Slim V2 - Thales Tonarm Introduces the TTT-Slim II by Rom Beyerle

Another huge weekend for the audio world at Munich High End trade show 2017 has come to a close. We are busily updating our website to reflect the many new additions to product lines, and excitedly fielding enquiries from those already in the know.

Thales Tonarm's innovative minimalist battery powered turntable designs have been a favourite of ours for quite some time. The updated TTT-Compact II released last year was widely applauded for its next level performance, in our demonstration system at the Melbourne International HiFi Show 2016. Together with their highly popular Tonearms "Simplicity" and "Easy", Thales turntables have found homes with many Australian music lovers, who appreciate the very dynamic, detailed performance and minimal design. By compressing every element of the turntable construction, Thales are able to create extraordinary mechanical stability, unobtainable by many larger more elaborate designs; all within a compact footprint.

This year Thales have shown their brand new TTT-Slim II Turntable. The smaller sibling to the TTT-Compact II has received a comprehensive facelift and is stunning in both visual appeal, performance and ergonomics. New transport spacers, high density platter inlay and updated motor decoupling dampening system are just a few of the latest improvements over the original TTT-Slim.

The Slovenian High End Audio Experience - Kuzma Analogue Academy by Rom Beyerle

Hotel Zaplata Preddvor, Slovenia


With the excitement building towards the Munich High End show- just a little under two weeks away, my thoughts are cast back to around this time last year. I was lucky enough to be invited, and attend the inaugural Kuzma Analogue Academy, an amazing concept of Kuzma Analogue owner and founder Franc Kuzma.

Kuzma Analogue have long cemented themselves as one of the world’s leading high end turntable designers and manufacturers, with legendary analogue reference equipment. Such as; the Kuzma Stabi Reference turntable, XLDC and most recent, Stabi M turntable. Not to be forgotten are the exceptional reference tonearms such as the renowned Kuzma 4Point, Airline and the many variants of the Stogi S and Stogi Reference. Kuzma has forged a huge reputation for their tremendous build quality, iconic design and superb technical, ergonomic and of course sonic performance.

With distributors on six continents and dealers in more countries than I care to count, Franc Kuzma extended the generous invitation for a limited number of distributors, press and dealers to visit the home of Kuzma Analogue in Slovenia. An opportunity to bring expertise together and explore and learn Franc's own tricks, techniques and philosophy on turntable setup, with an official exam and certification from the Analogue Academy at the end.

For many of the twenty odd attendees from as far afield as Brazil, Thailand, Japan, Malaysia and Australia. It was our first time to Slovenia, and a real pleasure to experience 4-5 days of Slovenian hospitality, humour and tradition. Arriving mid afternoon to Hotel Zaplata, where the entire small traditional style Slovenian hotel had been booked out by Kuzma following the huge interest in the Analogue Academy (originally numbers were predicted for 8-12people). We were greeted by the fantastically friendly staff at the hotel, a huge Kuzma banner at the front door, flagged by the giant taxidermy animal window display, boy do they like hunting and animal wall hangings there! Before I could sit my bags down I was greeted by Franc and invited to meet the many attendees who had already arrived. Basking in the afternoon spring sunshine, looking up to the nearby snow sprinkled peak from the quaint roadside hotel; everyone enjoyed some local brews or wine and got acquainted.

Dinner was a traditional Slovenian feast of many mainstay dishes, Franc was the ultimate host in opening the Analogue Academy, welcoming us all and giving thorough introduction for us to Slovenian lifestyle, food(Franc himself had played a big part in designing the menu for the evening) and their slight inclination for a beer or wine. A few bets, taunts and challenges were made regarding passing the Academy setup exam for a few days time and we all hit the hay.

Friday began with a very thorough outline of the course content and practical plans. Followed by a valuable series of comprehensive theoretical lectures from Franc and his team on analogue design, challenges, Kuzma products and their own setup methods, tools and techniques.

 Franc, whilst at the top of his game and an absolute expert in the field, graciously remains very open to other opinions, set-up tools and people’s hands-on experiences with different equipment. Many of the distributors have been working closely with Kuzma for many years. These are professionals with vast analogue experience, who are dealing with real world system setups, and troubleshooting on a daily basis. Analogue setup experts who provide the very best service possible, to supply and support Kuzma products all over the world. Whilst many customers have experience and skills on analogue setup, to extract the very best from an analogue source, there are very tight tolerances to adhere to. When available, it is always suggested that turntable setup is carried out by Kuzma product specialists. This is, and should be your retailers mission, to setup, oversee and ensure that you are getting the absolute best you can from your precision instrument!

Moving on, with hugely filled stomachs we were given the opportunity to work on all Kuzma products, and practice the Kuzma setup techniques. In-between, small groups were ferried off to visit Frank Kuzma's own office. His astounding record collection, and amazing high end system were showcased, and we enjoyed a taste of his own reference system used for testing and comparing new designs.

A luxurious dinner in a nearby village saw us all rolling out of the bus for bed after a feast of locally sourced ingredients. This included a head chef who hunts and cures his own salamis, sausages and many other meats…A carnivore’s paradise!

Saturday was much more practical, with testing and exams. All attendees passing with flying colours (of course), but not without strict assessment, triple checking by the fastidious production manager and employees. These gentlemen eat, live and breathe the precision that goes into each and every part, process and innovation of the Kuzma products, and expect it will be maximised with a setup of exacting standards.

Some interesting new products were discussed and shown by various distributors, including the AFI FLAT record flattener, and an audio specific piezoelectric vibration platform. Some varying ideals and analogue techniques were discussed. A great talk was given by journalist Roy Gregory, on his own take on analogue audio; which held some terrific discussion points for everyone in the industry, and audio passionates alike.

A visit to the Kuzma production house was extremely interesting, seeing the many production parts laid out in mass, vintage machining lathes still in service-better quality than what you buy new today. Assembly desks, electronics and wiring construction all in an extremely clean and well laid out light filled workshop, still buzzing with some late minute operations at around 6pm on a Saturday. Vinyl audiophiles wait for no man.

A celebration dinner at one of Ljubljana’s finest restaurants was spectacular and rather theatrical in its unfolding. Franc Kuzma continued to offer bus ride commentary, about the history and insights into Slovenia, and the surrounding areas as we went by. We met outside in a quirky outdoor beer garden, filled with antique machinery and interestingly repurposed and recycled furniture. Welcome drinks were already on order.

Inside the ambient lit “antique shop” feel restaurant, rows of records lined the back bar, and on a wall platform was nothing less than an original Kuzma reference turntable. After the greeting from the staff, it was apparent that Franc Kuzma is somewhat of a celebrity here, and from all reports, all over Slovenia. The charismatic, pride filled person that he is, it's easy to see why. 

 A huge feast saw us take over the entire restaurant, forming one giant horseshoe shaped table where the staff brought dish after dish and the head chef came to carve his way into everyone’s memories forever. Such was the performance and enthusiasm all night, no wonder Franc loves this place.

Terrific hospitality, new friends and stories aside, the opportunity to visit Slovenia alone was well worth the trip across the world. But the content, thorough planning and execution combined with the melting pot of knowledge amassed from all over the world, shared so openly for the benefit of all involved, made the first Kuzma Analogue Academy simply an outstanding event. All credit to Kuzma for creating such a terrific concept, and executing it with such style and thought. One can only hope we will see another KAA someday soon.

All the best to the Kuzma team at Munich High End 2017. I believe they have some exciting new product announcements to share in the coming weeks. Now to find a recipe for that famous Slovenian "Layer Cake".

*Kuzma were kind enough to provide a digital copy of the textbook theory from the academy you can download here. There is also plenty of other reading on the Kuzma website.

Science Meets Master Craftspeople - Thales Tonearm Technology by Rom Beyerle

Our fine friends and master crafts people at Thales have added a new technology page to their already very informative website, please read on for a great insight into the mechanics of what makes their tonearms truly brilliant. Further reading is also available on their website for whitepapers and brochures on all their outstanding products, or simply arrange a time with us to come and audition them for yourself. 


It all began when Micha Huber sought for a way to combine the advantages of a conventional pivoted tonearm and those of a linear tangential pick-up arm. The solution method is based on the well-known elementary school aid to construct a tangent: the Thales' circle. After much thought and calculations, a three-dimensional mechanical solution emerged that satisfies all the requirements placed on a modern pick-up system.

The long-cherished dream of geometrically correct tracking with low friction pivoted bearings became reality. A new patent was added to the dozens of existing patents that testify to this dream: CH 694567 Tangential Pivoted Tonearm, announced in May 2004.


Our philosophy is not only to find theoretical perfect solutions but also to realize them the most precise way and achieve continuous improvement in order to set new standards in music reproduction. Therefore, we invest into research and development constantly and we realized tangential pivoted tonearms with more complex mathematical background allowing more elegant mechanical execution.

Based on the experience that a turntable with its tonearm should be designed as one single unit, we have developed our own turntable-line which meets highest requirements. The portfolio is completed by our own phono- and line-cables.






While cutting the master disc of vinyl LP, the cutting-tool is hold on a massive support and guided linearly above the disc’s surface. This arrangement keeps the cutter-head rigid, even if high cutting forces occur.

While tracking the LP for playback, it’s totally different properties: the pickup-cartridge should follow the groove as smooth as possible and even tolerate eccentric and wavy vinyl. Therefore, radial pivoted tonearms are established as they allow to reduce unintentional forces at the tracking point tremendously. However, this mechanically preferred solution ends up with a geometrical error, since the cartridge is not guided tangentially to the groove anymore.

This so called tracking error basically distorts the music signal in a non-linear manner. By using non-spherical diamond tips (f. e. elliptical), further consequences as timing error and channel-differences in the frequency-response occur.


The unique Thales-solution combines in an elegant way the advantages of the tried and tested pivoted tonearm with the absolutely tangential tracking. This construction for which a patent was taken out on the 8th of May 2004 reduces the perfectly tangential tracking to pivot points, while the pick-up cartridge is taken and aligned on the Thales' Circle.


All triangles ABC on the Thales' Circle around M are rectangular in point C. Thus BC stands rectangular to AC and therefore tangential to the groove (red) with the radius AC. Because the pick-up cartridge is mounted exactly under point C and in the alignment of the straight line BC the tracking is perfectly tangential in every position.

From this completely new solution the following advantages ensue:

  • No tracking error and no consequential resulting distortions
  • Minimal friction because of pivot bearings; no linear bearings; no active tracking
  • Short tonearm with little resonance
  • Symmetric inertia at the tracking point in all axles


There is a small but mighty history in finding elegant solutions for tangential tracking of analogue records. Some of the inventors concentrated themselves on tetragon-geometry:



He announced in 1953 a patent with a tetragon tonearm where the cartridge was mounted in the middle of one side. Burne-Jones sold tonearms under his own name, and his idea was adapted several times.


This tonearm, published in 1970, is the best known solution working almost tangential. The cartridge tip was mounted exactly below a pivot-point. This idea made it possible to reduce the tracking error to +0.025 / -0.018°

Even if this solutions are not to be mixed up with the Thales-Original Solution – as the Thales is working on a triangle instead of a tetragon – the experience with the Thales geometry made it possible for Micha Huber to even optimize the tetragon solution and reduce the tracking error to 0.006° which is four times less than all solution published so far. This new geometry now made it possible to come very close to the perfect Thales geometry while using less parts and very elegant design.


The geometrical basis for the Easy tonearm is a novelty in tonearm-design. It’s the first solution by Thales where none of the bearing-points is located directly above the stylus. The clever arrangement of six bearing points creates three null points for the horizontal tracking error, plus a zero point for the variable offset angle. So, not only the tracking error is reduced, but the skating force as well.


The skating force is so called because it causes the tonearm to glide over the record from the outside to the inside, so to say 'to skate'. This force which draws the tonearm to the centre of the disc ensues indirectly from the friction between the tracking diamond and the record. This friction force always takes effect in the direction of the tangent line. If the pivot point of the tonearm is not located on the tangent, the friction force is divided into two components: one takes effect in the direction of the pivot point of the tonearm, the other takes effect towards the centre of the disc.


The force Ft results from the friction between the record and the tracking diamond. It acts tangentially. Because the pivot point is not located on the tangent, this force is divided into Fa which acts in the direction of the pivot point and Fs which is the skating force. The value of the skating force is not easily determined. It depends – first of all – on the music signal, further on the tracking weight, the circumferential speed and the tonearm and diamond geometry.

Therefore, even if the Thales-tonearms do track tangentially, their offset angle requiers compensation of the skating force. Since the offset angle for all our tonearms are lower than with normal tonearms, we do preset the compensation and it’s not adjustable for the client. For the different solutions, the compensation mechanism is solved as follows:

  • Thales Original: compensation-mass on a small lever, decreasing towards the inner groove because of decreasing offset angle
  • Thales Simplicity II: magnetical compensation between the two arm-tubes, decreasing towards the inner groove because of decreasing offset angle
  • Thales Easy: no skating compensation required, since the offset angle oscillates around the zero-point (straight arm)

the Record Revolution - MKII & the Kuzma Stabi S - High End Turntable at an affordable price by Rom Beyerle

As we see the burgeoning comeback of records and record players allover the world, it's exciting to see people back indulging in the beauty of vinyls. Young children in record stores excited over the latest LP releases, their parents alongside thumbing through crates of freshly wrapped brand new records while carrying a small cache of tasty fresh albums or classic re-issues, as seasoned bargain hunters and collectors scour the clearance boxes. This is just a regular day at any local big box media store. Many smaller niche record stores are also popping up allover. What's old is new again, and if anything it is simply lovely to see an excitement over physical media, tangible things for real people, made by craftspeople, with music created by real artists. People are back in shops meeting and talking with other music lovers, sharing and enjoying music and the experience of being part of whatever sub-culture their musical taste desires - true human interaction among all our digital disconnect.

We see statistics of amazing growth in records and players, and hope that they are all being used. For a long time many of us "audio nuts" have known the still superior sound that is achievable with analogue playback. As people begin the journey into and through exploring records and sound, we do hope it will spark even more intrigue in some to find the best playback system and sound for their records. The immediate yet delicate nature of records demands your attention to detail and we believe this is all part of the charm. A record player should be upto the task of playing back every detail within those grooves, and those audiophile weighted vinyl's should be played back on an audiophile player, capable of completely flooring all but the very best digital playback. A turntable should be easy to adjust in its setup, a joy to use in playback, stylish and complimentary in your home, and it's quality of fit and finish should be absolute, as you would expect from the quality of your valuable new or collectable pressings. It should last, with care, alongside you and your love of records well into old age.

Kuzma in Slovenia have been building turntables of absolute quality for over 30 years, and throughout the decline and almost death of the record, have toiled away refining and creating new tweaks and innovations, many of which designs have stood the test of time now for many years. Our introductory level turntable, is Kuzma's smallest offering, the Stabi S. The stunning T shaped solid brass construction takes technical design elements from far more expensive tables. It offers the fine, delicate finish of all Kuzma products and performance of incredible value for money. Truly stunning in it's appearance and performance, it can be mated to a wide range of tonearms, and also offers pathways for upgrades should you ever desire. True master craftsmanship at an affordable price, the Stabi S is a desirable table of a quality surpassing other tables of similar value with ease. On demo in our Melbourne showroom.
