Design concept :
1. Single belt drive turntable problem
A. For every turntable, the plater bearing must have a gap, size may vary, but in general the gap is needed for the plater bearing to rotate. In theory every player should have its dynamic balance so the plater bearing stays centered to reduce bearing noise or fiction. However, in reality it’s difficult to achieve due to problems in production or turntables wrongly set …etc Many factory choose to statically balance their plater, during rotation the bearing tilts as a single motor pulls from a different direction. This is the cause of noise problem for most belt drive turntables.
B. Another thing about single motor, The belt contact plater surface about 1/2 turn,If calculated with a tangent，belt quilts, (elasticity，tension, grip force) , after using a while, turntable drive belt getting old, belt getting lose, belt torn out. these will direct effect motor control turntable speed.
2. Turntable belt geometry
Typically for single motor Turntable, the belt contacts the plater surface for approximately 1/2 turn if calculated by tangent. The belt quality (elasticity, tension, grip force) deteriorates as time increase. Belt can turn old, get lose, torn, or wore out. These factors directly effect motor control of the turntable speed.
**But the relative choice of three motors, you must use a more quiet motor, so that the three motor noise is less than one motor.
3. Special suspension system
Magnetic bearing in the current turntable industry is not an innovative thing, but most of the magnetic turntable design uses magnetic bearing to reduce ball bearing pressure, this way it still can not reduce un-dynamic balance plater noise, the Uneven magnetic field in rotation plater will increase the noise.
Our turntables are also designed with magnetic bearing, but we are completely suspended, with specially designed belts which fixed bearing in the center of the sleeve, and via three-motors independent suspension system in 3D direction, the vibration come from out side will be eliminate or isolated .
The motor suspension system, also keep the belt tension constant, even with time the aging of the belt won’t change the rotation speed.
With a low residual energy of the acrylic light weight plater, keep the turntable unbalanced rotation under control, the bearing offsets the noise to a minimum.
4. Advance motor control system
TT3 turntable uses BLDC (Blush less Direct current) motor with low torque, by using a CPU to generate PWM signal to control server motor, unlike PLL circle, our control signal is more stable and will not drift easily. Can easy achieve 0.03% drift/mins( industrial stander is 0.3%)
5. DC power supply use over 22000 UF to make sure, DC voltage and current is stable
6. Precision POM Pulley cause less error for turntable speed.
7. The base of plinth is made of air craft Aluminium which is about 12KG , with 250 degree high temp powder coating. It can seal metal, also create a nature sound than bare metal. Besides the sound, you can choice different colour to match your interior or sound system.
8. Our turntable have full bass sound, you will find that it’s small but with powerful sound.

Design concept :
From ease to use for consumers and to serve demanding cartridges.
We have been in the retail analogue audio business since 2002 with focus on analogue gear. I had sold many high end turntables and also repair and adjust them in Taiwan. As an designer with architecture background, I design the products with passion.
The Viroa Tonearm was designed 10 years ago, the basic idea is using a simple tonearm. Design begin with a special bearing and magnetic system for azimuth use. The result turned out very well, however the bearing was difficult to reproduce, so I start to seek other methods to achieve this goal. During this experimental process, we discovered an important issue:
** tonearm design is to service the cartridge not the groove **
*Majority of Tonearm designer only focus on tracking, when they focus on tracking, the cartridge just a needle, but they forget it’s the cartridge that holds the stylus to touch the tracking groove, not simply just the stylus.
My design focus on how the Tonearm serves the cartridge, and let cartridge track better, when tracking is better the cartridge will sound much better
As every one know, high end cartridge has magnetic field, like MC, MM, MI. All types have magnetic field in order to generator electronic signal for phono amp. When you place the coil, magnet or iron into the magnetic field, it is like directing an orchestra, it does not have physic contact, so every thing is elusive and difficult to predict. The tonearm need to control the magnetic field, or expand this magnetic field to the fullest.
1. Magnet damping and anti skating design combine the viscosity of magnetic force. Our Magnetic damping system is the most efficient system. It combines azimuth adjustment and anti-skate; it also keep the cartridge in good tracking. This system is simple with minimal mechanism, the Tonearm is free of interference without the extra mechanisms.
2. How Magnet damping work? When we experiment with magnet we discover viscous force pulling from either polarity. When it’s in force you can’t pull object away from magnetic field unless it escapes velocity. When cartridge is tracking in the groove, the viscous force keep the needle stable therefor it will generate higher electric energy and more detail from the groove. Coincidently bass region of the music will benefit from this phenomenon.
3. As most tonearm on the market today all has fix value for anti-skating adjustment. But the actual records spins with inner circle much faster than outer circle, hence anti-skate demand is a variable. Viora tonearm’s magnetic anti-skate device effectively stabilized the needle m’s travel and progress alone the groove spinning from most outer to the inner circle with better tracking ability.
4. Ease of use
A. install cartridge with gauge in a safe place
B. Good to adjust azimuth
C. Easy to adjust anti-skate
5. Lower counter weight design will have close to the effect of dynamic balance stylus pressure, you can make the vertical track better with a special rubber damping design, you can eliminate unnecessary bass rendering.
6. Special design tungsten steel bearing needle with a smooth sapphire bearing housing, you can ensure that the rotation of the bearing noise, not transferred to the cartridge.
7. Van Den Hul silver Litz wire for tonearm inner cable to make sure sound quilty.
8. Demo magnetic system (with & with out magnet) **Please listen to bass sound.
We are selling the TIEN TT3 with Viroa at S$5,000 as introducing price. Hana cartridge can be bundled at very attractive price.
Please drop by our showroom for a demo. We also do home demo if you happen to be interested. Trade in service also available
Thanks & Best Regards
