A power amplifier is an essential device for configuring the audio system with its role in the process of operating the speakers. Since the beginning of the use of the vacuum tube to the establishment of the class D amplifier, nowadays which is called the digital amplifier, the amplification technology for the amplifier has been dramatically evolved.

Although some believe that digital amplifier is insufficient as a high-end audio device, but, based on SOtM’s unique technologies, the sPA-1000 will be the one can break this bias.

Since we designed the Class D amplifier module for sPA-1000 which is not like the most Class D amplifiers that use the ready-made modules by a few amplifier module companies, it means that the sPA-1000 is inherently different from others, and can outperform.

In particular, the sPA-1000 uses the power stabilization technology (pumping reducer technology) to the power circuit which removes the power pumping phenomenon – when playing music on the speaker, the electromotive, force is generated and it changes the power voltage-, and with this special power circuit, the sound could become more natural and bring more details, and most of all, you can play very precise low and mid-high ranges music. 

In addition, from the input stage to the speaker output stage, fully balanced circuit has been applied to withstand the noise generated inside and came from outside the product.

Such several special technologies applied to the sPA-1000 is the great advantage of the products which is barely found in any other D class amplifier. These techniques will give you a chance to get closer to the essence of music by clearly expressing the nuances of the performers’ playing music.

The SOtM’s Ultimate products which are completed with a simple and modern design that have been verified through a multiple design awards, the full ultimate system can be perfectly composed to enjoy the best sound with perfect shapes.
