The merit of string driven turntable system
This very simple structure turntable system would have one of the ideal figuration for getting high quality reproducing. Because that it’s component is only a few parts, a turntable, a motor and a string. They don’t need any other mechanical structure or parts. And so if we had done research on each component, we could manage to reach at certain quality level. I should agree that belt driven turntable system has same component like as string driven system except belt. Well, which would be desirable belt or string? It’s a hard question because that belt and also string have each advantage and disadvantage. A belt is made of some elastic material, such as grinded urethane rubber. And the tension by this elasticity, 5% to 10% added extension, can transfer the torque for turntable. So it is easy to install and use. On the contrary, string has some difficulties to manage. Speaking strictly, string has some elasticity like as belt, but if we adopt string for the system, we have to use very critical only a few % added extension for getting nonslip transmission between pulley and string. And so making a full use of string is quite difficult. But this string has tremendous virtue. The string could transmit the circumferential velocity of the motor pulley to the turntable velocity without any delay. Because that the string works as rigid material rather than elastic body. At the same time, the belt itself is elastic material and so the motor pulley and the turntable work with some springs and dampers because of this elastic body. And it inevitably causes some delay of the motor servo, when the load of turntable fluctuates. We could sum up, fundamentally the string driven turntable system can bring out outstanding high precision rotational accuracy according to constant-speed rotation of the motor, the most significant necessary requirement for turntable system.
Again, string driven system might be hard to making full use of the potential but GMP-8000 has built in adjustment mechanism for the string tension and so once you succeed this alignment of GMP-8000, it will allow you rediscover new appeal of analog LP records as “the ultimate high-resolution sound” with the excellent drive system.
Built in manual adjustment mechanism for necessary string tension
We are living under the world of some physical laws and the law of inertia is the one of close to us in such laws. You can remind the law, a car can keep speed for some moments when you get of accelerator pedal. It could be applicable also to body of rotation and the mass of rotation is the inertia moment. And the momentum of constant-speed rotation is proportional for the amount of inertia moment. So GMP-8000’s exceptional gigantic inertia moment made from precious gunmetal with high-precision processed reaches to 3,260kg.cm2, can assure of outstanding smooth and precise rotation. And also luxuriously beautiful, well-sounding and heavy weight, up to 14kg gunmetal turntable would bring you some delights of possession.
Highly rigid chassis by laminated veneers of Finland birch
The birch takes a long time to grow in the harsh cold environment of North European. Accordingly this wood has a fine grain and high density and so the laminated veneers have favorable planarity and rigidity. Of course, the material is also blessed with some of the internal loss of natural wood. And so the laminated wood could be some kind of ideal material for audio use, such as speaker boxes or this type of turntable chassis. The thickness of the custom laminated board is reached to 90mm and manufactured by high precision NC wood working machine in Shirakawa Co., Ltd, a famous furniture maker at Hida-Takayama city, beautiful historic town. You could find also woodworking is the Japanese traditional handicrafts.
We could offer you custom-made tone-arm base for fitting to your favorite 12 inches tone-arm. And this base is made from aluminum and machined to 12mm thickness with highly processing accuracy. Furthermore, this base can be fixed to the heavy under base of copper alloy ring geometry. Yes, this under base is tightly fastened on to the Finland birch laminated chassis. These combined material, robust and rigid but also has somewhat internal loss could bring out natural vibratory control around the parts of tone-arm mounting. And also the motor base structure is same as these tone-arm bases. As already stated, built in adjustment mechanism for the string tension is adapted to the aluminum motor base and the under base of copper base alloy ring. This structure provides for effective damping of the DC core-less motor’s minimal vibration.
On the belief that “ the joy of music is only found in ‘Real-Sound’”, we have been developing and marketing high-end audio products with the wish of communicating and sharing the sensations, also excitement of our “Real-Sound” music with our customers.
Through High End 2014 in Munich, we will demonstrate four integrated amplifier models including the RSA-F3EX, M3EX, V1EX and 717EX.
With extensive use of latest Class D solutions boosting revolutionary speaker drive power and advanced energy-saving performance these amplifiers deliver beautiful tones and fully dynamic sound, in a word true richness of music someone has never hear before.
And also REQ-S1EX, a phono equalizer amplifier fusing the latest semiconductor technology and matured analog technology, will allow the listeners of analog LP records to rediscover the fascination with “the ultimate high-resolution sound”.
