Amazon Audio

We started as an end consumer with AMAZON Audio when i bought my first AMAZON Model One. I set it up with all 47 Lab equipment, a ZYX cartridge, and a miyabi 47 Lab cartridge. As much as I loved AMAZON Audio Model One, my only regret was that i had not dived all the way to get the AMAZON REFRENZ model. One upgrade and two turntables later, Hartmut  Janssen asked SORAsound to represent AMAZON Audio in North America.

Hartmut has now become the big brother we love. As for the tables, they are a class act: gorgeous, built with precision and have an amazing sound. SORAsound imports the following models of AMAZON Audio:

Amazon Model One

Overall weight: 24 kg
Platter weight: 5 kg
Platter diameter: 320 mm

AMAZON Audio model turntables share some basic engineering ideas described in the following sessions. The chassis of the drive is made from a special ICI material to ensure virtually no resonance. This has very good internal damping features, partly because it is casted. AMAZON also use 6 LRP elements (Low Resilience Polymer) in its sub-chassis-construction. The LRP elements are arranged in the chassis corners and around the platter bearing. It is pretty easy to set any of the AMAZON Audio turntables. You only have to pay attention to the horizontal adjustment.

As seen above, AMAZON MODEL ONE has a platter that weighs about 5kg and is made from casted metacrylat. It actually is very similar to the vinyl. During a very complex, temperature optimized process the platter gets drilled to its exact dimensions and afterwards follows the quenching and tempering of the surface. This process prevents stress in the material, which would affect the acoustic qualities. Resonance diffuser in the inner area of the platter eliminates the well-known material resonances in massive plastics platter in the area between 9 kHz and 13 kHz.

The rotation-center of the platter is a ceramic ball in the middle of the inversed bearing. Both the bearing bush and vertical axis are made from multiple hardened steel. Accurate selection of components guarantee a perfect, noiseless operation and years enjoying your AMAZON Audio and music. All moving parts are supplied with a very thin but very good greasing special oil from a oil reservoir at the bearing base. Due to the massive body and the special geometry of the bearing, AMAZON Audio platter bearing doesn’t tend to oscillate like many other turntables. That is proven by objective measurements AMAZON Audio has made using a pulse measuring process. Pulses at different areas on the platter are dying out consistent and without excessiveness. An important advantage of inverted bearings is their high fulcrum, which minimizes tilting and moving.

The drive unit is totally separated from the running gear. A very thin string carries the power from the pulley to the platter. You can switch electronically between 33 rpm and 45 rpm. A LSC-Controller (Linear Speed Controller) monitors all the time the speed and keeps it absolute constant. These from AMAZON developed controller are only used in Amazon turntables. In addition, you can fine-tune each speed separately. Therefore we use padder with a gearbox 1:25. The heart of the drive is a DC-motor, which is usually used in nautical navigation devices. This motor is stored isolated and swimming in a massive box. The result maintains its constant speed with smoothness.

The integrated rechargeable battery power supply is unique for analogue drives. In play mode, the rechargeable batteries as well as the motor are totally separated from the mains supply. Thereby, all the disturbing influences from the mains supply are kept away and smooth operation of the motor is guaranteed. All AMAZON motor units have an intelligent circuit, which monitors all parameters of the NiMH-batteries while charging and discharging. The system recharges the batteries automatically, when it is not in use. One charging cycle is enough to listen to 180 LP’s.

AMAZON Audio AMT One Speakers

AMAZON A.M.T. One $17,995.

Hartmut Janssen’s works are special because of his vision, talent and uncompromising skills. In 1985, Hartmut found Audio Physic speakers company, together with Joachim Gerhard and Willi Hegener. They built the first speaker models, Tempo and Spark at their kitchen table in his house. Their first review was in the famous German High End magazin Das Ohr. It was a great review. In the next years the company grow and grow and now Audio Physic is one of the famoust speaker manufacturers in Germany.

AMAZON Audio developed its first AMAZON speaker – the AMAZON Line Source in 2001. It was also a dipole construction working with 16 fullrange units on each side. AMAZON Audio was the 2002 recipient of the Image Award for the best speaker of the year.

Now, Hartmut has reached his dream by creating AMAZON A.M.T. One which is one of the most unusual and exquisite 2-way loudspeakers currently available. Its no-frills, yet elegant design is based on the tried-and-tested design principle “form follows function.” The speaker’s open baffle design (it consists merely of an acoustic baffle holding the transducers and a stiff frame required for static reasons) uses no coupled enclosure whatsoever, thereby avoiding any undesirable sonic side effects, which in turn results in a lively sound and stunning dynamics, completely devoid of any “boxiness”. By experimenting with the speaker’s positioning in the room, you can also influence the room’s acoustic response in respect of critical modes, due to the speaker’s dipole design.

The secret lies in combining a Wide Range Air Motion Transformer (A.M.T.) for the high end with an extremely fast, short-stroke 15″ cone driver for the low end, resulting in a lively and seamless sonic reproduction down to the lowest octaves. The filter technology developed by AMAZON Audio permits a low crossover frequency of only 700Hz for the A.M.T., while minimizing the number of components in the signal path. The entire system’s efficiency amounts to more than 92dB.

The A.M.T.’s functional principle differs completely from that of conventional spherical, ribbon or cone tweeters. The air oscillation is not generated by piston-like membrane movements along the reference axis, but instead by utilizing a lateral force acting across the reference axis, i.e., rotated by 90 degrees. The membrane, which is pleated like a bellows, accelerates the air equally to the front and the back when driven. Due to this principle and its inherent speed, the A.M.T. is the ideal tweeter for use in dipole speakers with an incredibly clean and accurately delineated sonic reproduction up to 24 kHz.

Due to its lightweight, yet stiff membrane, the woofer’s ultra-fast response constitutes a perfect match for the A.M.T, which is renowned for its extremely short rise time. Instead of long strokes, the woofer works with a high membrane surface and a powerful generator, which makes conventional long-stroke woofers sound and measure like “slow trains” by comparison. In order to absorb the resulting impulses, the woofer’s die-cast basket is embedded into a solid baffle made from sandwiched materials and measuring 40mm in thickness.
