The Heed 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 (isolated analogue and digital sections to ensure the best possible playback and accurate performance). The inputs consist of 5 + 1 digital inputs (1 x RCA coaxial S/PDIF input, 1 x BNC coaxial S/PDIF input, 2 x Toslink optical input, 1 x asynchronous USB input & 1 x auxiliary input for expansion card). The auxiliary input should allow for possible streaming facilities in the future.
Beautifully concieved and built - the Abacus has easy to use front panel controls, with simple toggle switch for input selection. A remote control enables simple remote switching of the digital inputs. A circular display gives you the sampling frequency for simple and informative feedback.
The Abacus is perfectly partnered with its stablemate the Elixir integrated amplifier, and can be purchased together as a 'Duo' system for a perfect 'proper' high quality entry level Hi-Fi system - to span the digital and analogue world.
Available with a black casing/black front or grey casing/silver front (please specify on order).
