A) No other turntable in the world has so precise pitch. B) so precise rendering ground tones and overtones C) No other turntable has so realistic rendering of deep bas notes. D) comparing master reel to reel analog recordings and the same recording on Vinyl is a fantastic experience,  The Sati turntable is dam close to  the original first takes of the tape recording. E) Direct to dish vinyl is fantastic.

the Sati display with the 50 kg massive platter and the best turntable DC motor turns round in a perfect combination   grounded with a massive ball bearing. This classic combination is the reason why the Sati outperforms all other high end turntable.  Many high end turntables use magnetic bearing or air bearing, Exact this kind of technic is disable the turntable to reach ultimate bas performance, they will go as deep, they will not have the same finesse and detail in their rendering bas. This kind of performance will be heard in many octaves above as a lack of body.  Lack of hearing between ground tones  and over tones.

the  50 kg platter is doing the rest, neither two platter turntables where the second platter is running in opposite can come near the perfection of a 50 kg platter running in perfect pitch, a piano sound displayed with perfect pitch is fantastic to hear, all music is fantastic to hear with perfect pitch, The SATI is the top and above the rest in the turntable industry.

The next chapter is elaborating more about the Sati record players unik state of the  performance.
To follow this goal means building a uncompromised record player with the best materials you can find and with clever combination of old and new knowledge. What I came up with was a incredible record player with a performance that has never been achieved before. Its performance is like listening to direct studio mastertapes. This is a fantastic experience.
The success of the SATI lies in its unique combination of a supremely massive 50 kg platter(with bolted polymer mat), state of the art motor and its custom high tech main bearing. The proof of Sati’s success is not only in the ability to produce superior wow and flutter statistics, but it is easy to hear as well. For a start, listen to a good piano recording. The piano, in particular needs accurate pitch, sustain and decay for maximum enjoyment. Some companies try to achieve absolute pitch by adding three motors to turn the platter, but they forget that three motors can never run at absolutely the same velocity. Thus sullying the signal with constant speed shifts. The problem is made worse when the turntable is suspended: floating in all different directions, causing additional speed fluctuations. Each time the speed fluctuates the listener looses vital information that separates reality from ‘hi-fi”. Sati narrows this gap like no other turntable in history. Some companies will add fly wheels in order to repair the speed accuracy. This is merely a band-aid to try and help a weak turntable motor. But not so on the SATI, you will hear no improvement by adding a flywheel or additional motors!
When it comes to speed stability in the presence intermittent drag (the needle in the groove) you simply cannot beat pure mass and momentum. It is simple physics. At 50 kg the Sati platter is 3-5 times as massive as most competitors ‘high mass’ platters. It even trumps the great Micro Seiki SX-8000 and Continuum Caliburn by a margin of 25%!! No commercially made platter comes close to the Sati platter. Not only is the Sati platter more massive, but its cast aluminium composition gives it superior damping qualities to those of acrylic, lead, steel, etc. Another important quality for a record players performance is the platters ability to always maintain neutral support to the sound. Neither too damped (some record players platter is made with Rubber, glue, lead etc. and is sounding thick and slow!). Nor too rigid: plastic acrylic platters lack bass performance and will always have a signature resonance. The acryl platter adds a layer of noise over all the music.
The all important main bearing is a 12 mm tungsten ball which can carry a 500 kg platter with ease. The tungsten ball is the heart of the bearing along with the 16 mm axel. This bearing system produces an ultimate flow of resonances out of the platter, and the reason why the SATI plays better than other high end turntables with magnetic bearing and air bearing where the resonances stays inside the platter. Magnetic and air bearing tables have no ultimate grounding of resonance. Air bearings and magnetic bearings therefore work as a high pass filter and will, as a rule, have less bas and the sound will be brighter and thin! When the Sati is playing, people are surprised over how much body, control and foundational bass exists in even the most familiar recordings.
If you look at all other turntable brochures today, nobody really wants to talk about their motors, because they are not at all up to the desired standards! In the sixties we had much better motors, At that time you could buy excellent flywheel motors which had a controlled feedback system with an optical encoder!
The Sati motor is not a flywheel motor but a flat high inertia 12 pole motor with three hall elements which are controlled by an optical encoder 2048 times every time the motor runs one rpm. No other motor on todays turntables has a 12 pole BRUSHLESS DC MOTOR.
The old SATI motor was a two pole brushless motor from Origin Live and they also made the analog speed control, but that motor had difficulty maintaining the same speed, it was drifting. Many owners of Thorens, Linn and others have upgraded there turntables with this Origin Live motor. In America they also uses this small two poles motor on the Teres and other turntables.
The ClearAudio Reference turntable uses a 4 pole motor but unfortunately with low inertia and much less ‘horsepower’than that of Sati. In automotive terms; the ClearAudio motor is a 4 cylinder ‘engine’ to Sati’s 12 cylinder. While low power together with light plastic platter yields a constant speed, the high inertia motor of Sati combined with its massive platter give speed control under even the most demanding vinyl recordings. The result is a naturalness you can hear; decay and sustain are brilliantly captured.Voices take on a human emotional element never heard before. And the bass is now a solid driving foundation to the music- just as in real life.
The 12 pole SATI motor is controlled in a unique way because its not controlled in standard digitally way. It’s controlled by three soft sinus wave signals.
In the very beginning I had developed a tube controlled powersupply which was controlled a very good Papst pancake motor, This had the wanted soft wave control, but only one wave.
If you use digitally zero to one (with 0-1) control, will it control the motor very hard! On the scope you can see it as small zigzag peaks, the motor do not like these peaks and will act acordingly (it will not flow fluently). This is very easy to hear in comparison. 90% of high end turntables are controlled this way.
With the new SATI motor with high power output, the single soft wave is expanded to three soft waves, and these are controlled by three hall elements, which al the time are controlling the 12 poles to run in exact and constant speed. The more times the motor is controlled, the more exact it is running, and now we are free of all this drifting every time we turn on the turntable and we are also free of the digital distortion where the motor runs zigzag.
The old motor weight was 36 gram the new is 0.7 kg. Furthermore, the new motor employs soft start, it takes about 6 seconds before it’s running full speed.
. The new motor is so strong that you can use a cleaning brush while you are playing your music without hearing any speed change. The motor has such strength and accuracy, combined with the platter’s massive momentum it can hold the 50 kg platter like an iron fist. The specially formulated belts’ elasticity has absolutely minimum interference.
The platter and the tone arm are integrated with a 40 mm thick alumium plinth, and the arm board is a massive 150 mm aluminium tower. This strong integration is responsible for the arm and platter resonating in sync with each other. This becomes a problem in turntables where the tone arm plinth is placed outside the platters plinth. The Sati plinths feet have their own design with low resonating, anti vibration gel between the plinth and main table support. To totally optimize the Sati Turntable an air table with very low resonance should be placed underneath the Sati Turntable to filter out lowest frequency disturbance.
The SATI Transference Ultimate record player achieves a new reality for playing analog records. No digital system can match the sound quality of a good analog recording.
The Sati Turntable was made for the pure love of music and the joy it brings, nothing more, nothing less. It is a heart warming experience.
You owe it to yourself to listen to the SATI and you will be both thrilled and surprised at how real-to-life good vinyl can sound. The Sati Turntable is a new level of music reproduction.
