Integrated Amplifier

The abacus is one of the most recognized calculating tools of humankind. It has been used for thousands of years, for its simplicity, and for its general acceptance that connects people of various cultures and beliefs.

Our Abacus digital to analogue converter is an exquisite tool for the task, connecting you to the world of the musician, doing the precise calculations needed for the mutual understanding. Being a gateway between the digital and analogue worlds, the Abacus is not only a computing machine, it is the very source of the analogue sound amplified through your system. This sound needs to be fascinating right from the beginning, isn't it?

The Abacus can interpret this seductive Heed sound from a great variety of digital sources, even if the music is coded in extremely highly detailed PCM or DSD signal.

PCM and DSD are the two main methods for digital recording. The Abacus can handle PCM signals up to 384 kHz and 32 bits, and natively processes the double speed DSD. Quartz based clocks and well-designed linear power supplies ensure that the resolution of digital processing is always perfect.

The analogue buffer stages of the Abacus are made of discrete components, to allow the best possible first steps for the analogue signal.
