Vertere Acoustics announces new DG-1 S


Press release | Touraj Moghaddam, founder and chief executive of Vertere, today announced that the multi-award-winning DG-1 record player is being updated and improved.


It has been three years and three months since the launch of the hugely innovative and hugely popular DG-1. These three years have been like a lifetime in standard years with a pandemic, supply chain complications and shortages, and multi-national inflation. But one benefit - it gave Touraj time to think; as anyone who knows Touraj well realises, the time to think always means product improvements. Interesting times bring exciting products. "Improving music reproduction by a million tiny steps – some not so tiny." The DG-1 S will be available in September 2022.

The DG-1 S improvements bring higher resolution replay, greater dynamic contrasts, and improved stereo separation with greater precision while simultaneously keeping the musicality the DG-1 delivers with great aplomb.


Summary of the DG-1 S Improvements

  • Improved platter bearing – The precision machining and polishing operations have a higher tolerance with the variation halved statistically. The super smooth finish bore with the precision Tungsten Carbide interference fit ball delivers lower noise, lower rumble, a lower effort for the motor and less rotational variability.
  • Groove Runner S tonearm – The arm beam is now constructed from a five-layer polymer laminate bonded to a second five-layer polymer laminate. The PCB flex signal carrier is bonded in-between the two laminates. The profile of the arm and bearing has improved the counterweight/bearing/headshell/cartridge alignment.
  • Improved tonearm bearings – The Vertical Kevlar thread bearing is now adjustable for tension and azimuth. The Horizontal nylon thread bearing is now fitted with greater precision to ensure even greater consistency.
  • New Motor Drive software allows separate adjustment in two steps, initially the sine wave voltage and then the cosine wave adjustment at the final stage for the absolute lowest noise and vibration. Improved coupling between the three plinths – improves resistive damping and reduces noise

Background to the design

Vertere Acoustics is best known for its extreme high-end designs loved by audiophiles worldwide. The Reference RG-1 Turntable and the Reference Tonearm compete on equal terms with the world's best.


The new DG-1 S Dynamic Groove Record Player targets a less extreme customer driven by performance who almost needs Plug and Play setup. From Vertere's research, this customer wants ease of setup and use but not at the expense of future upgradeability.


To design a record player that will sell for 3550 GBP, 4148 EUR, 4995 USD, 7000 AUD including Magneto cartridge when the brand's existing designs can sell for 200k GBP requires a back-to-fundamentals approach. Taking his existing ideas, reducing material quality, and slackening tolerances would not be the Touraj way.


Back to fundamentals involved examining every design element, rethinking the way turntables work, and removing every superfluous element that got in the way of the ultimate aim: getting the listener as close as possible to their music.


Everything has been redesigned and re-engineered, from the plinth to the arm and its bearings, developing some of the basic principles of a record-playing system while completely rethinking others.


Touraj Moghaddam The result is an elegant turntable that looks like no other. It draws on the engineering of the reference models to deliver outstanding performance and ease of operation at a newly affordable price.


"The job of a record player is very simple and very linear," says Touraj Moghaddam, "the most accurate measurement of something going past the stylus and throwing it from side to side over 1000 times every centimetre."

Vertere DG-1 S The core elements in more detail

  • The Motor - The motor is the most crucial part of any turntable: it's the only source of energy for the signal generated by the cartridge and fed out to the amplifier, so quality and accuracy are vital. The DG-1 motor system is derived from that developed for the flagship RG-1 Reference Motor Drive: it uses the most advanced motor drive, delivering the best possible performance. The motor itself is a low voltage 24-pole Precision Synchronous design, individually tuned for the lowest noise and with an offboard power supply. An addressable microprocessor PCB controls it during manufacture to ensure accuracy and programmability for future upgrades. A copper and stainless-steel cover provides shielding from both inward and outward interference.
  • The Platter assembly - Drive to the platter is via a precision machined aluminium alloy pulley on the motor and a bespoke silicon rubber drive belt, with electronic speed change for ease of use. The platter is also a precision machined alloy, bonded to a PETG record interface mat, and, on the underside, a cork/Neoprene/nitrile disk bonded to control platter resonance.
  • The Bearing - The platter fits onto a super polished stainless-steel spindle that rides in the main bearing housing on a super precision tungsten carbide ball. The complete main bearing assembly is long-term lubricated for longevity and ease of use. This avoids regular repeated recharging of the bearing lubricant, which is essential to prevent premature wear and damage—another example of simplifying this turntable to optimise performance. In addition, the new super-precision bearing delivers lower noise, lower rumble and lower rotational variability.
  • The Groove Runner S Arm - The DG-1 S arm is uniquely Vertere and differs from conventional thinking in its use of a flat profile in place of the usual tube. Conventional arms use tubes for stiffness, but these can bring all kinds of problems with high Q resonances and thus the need for critical damping – costly and complicated. The DG-1's bonded double five-layer, non-resonant tonearm beam avoids these problems. In addition, in place of conventional tonearm cabling, a flexible PCB is sandwiched into the arm to carry the signal from the cartridge to the output terminals. Completing the arm are a stainless-steel counterweight with azimuth adjustment and a fine adjustment tracking weight, giving a total solution that's as simple and elegant as it is innovative.
  • Thread bearings - Many solutions have been sought over the years for precise bearings, but for the DG-1, Vertere has developed a very simple solution: twisted nylon – hundreds of 3 microns thick twined Nylon 6.6/6 strands – and Kevlar threads – one for movement in the horizontal plane, and two Kevlar for the vertical axis. These threads have many advantages, not the least of which is simplicity: they exhibit none of the Stiction – or initial resistance to movement – of conventional bearings, are super-light and noiseless, and the twist of the thread controls and damps the movement of the arm.
  • The Plinth - Like the tonearm, the DG-1 plinth is a sandwich construction, using non-resonant cast acrylic to form the main plinth and the sub-plinth for a clean and sophisticated look. This three-layer design incorporates the control button, the speed indicator and the user-selectable standby mood-lighting, as well as the silicon rubber isolation between the plinth and the platter assembly. The whole assembly sits on a steel chassis, chosen for optimal stability, housing the motor drive circuit and the motor, all supported by three new-design adjustable feet with Resistive Felt Pads.

The DG-1 S comes with a non-resonant Polycarbonate dust cover, where its hinges are integrated into the plinth for a sleek and modern profile.

About Vertere
Reducing engineering to its fundamentals, to get you even closer to the original recording.
When aiming to reproduce the complexities of music, it's all too easy to introduce even more significant complication in the engineering of audio equipment, putting in place one element to solve the problems until the whole design escalates into something fiendishly intricate - and expensive.
That's not the Vertere way: coming at the whole problem with decades of audio and mechanical engineering experience, plus close collaboration with the recording and mastering industry, we step back, take a long hard look at the fundamentals, and look for simple, elegant solutions.
That may sound like a simple "less is more" philosophy, but we prefer to look at it this way: the best audio equipment shouldn't add anything to or remove anything from the original recording. Instead, it should affect it as little as possible; bringing the listener ever closer to what the artist, producer and mastering engineer wanted you to hear.
