Vertere Acoustics, Park Royal London. Monday, 26th September 2022. Touraj Moghaddam, founder and chief executive of Vertere, announced that the new DG-1S record player is also available in white from early October 2022.
Traditionally product development at Vertere comes from two sources: A tranquil eureka moment for Touraj or conversations with distribution – a Push or Pull approach. This product came by a chance conversation between Touraj and Chelsea – Vertere’s marketing specialist – where she expressed a desire for a white finish DG-1S. It all went quiet until the next meeting, where Touraj proudly displayed the white DG-1S.
There was immediate consensus that the white DG-1S had to be immediately made available.
The white version utilises two polished soft-look cast Perspex sheets sandwiched around a constrained transparent Perspex inner. If you thought the black looked good, you have to see the white.
The white or black finishes will cost: £3550 (€4148, $4995, Aus$7000), including Magneto cartridge. And up to £4950 including Redline cable, Sabre cartridge, Technomat, and Iso-Paws.
Summary of the DG-1S Improvements – White or Black
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 – constructed from a five-layer polymer laminate bonded to a second five-layer polymer laminate, the arm beam includes the PCB flex signal carrier between the two laminates. In addition, 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 including Magneto cartridge when the brand’s existing designs can sell for £200k 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.”

| The core elements in more detailThe MotorThe 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 assemblyDrive 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 BearingThe 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. |
