Merason Reuss Digital to Analog Convertor
Merason's newly launched Reuss DAC builds upon the success of the Frerot. By utilising two DAC modules in mono configuration a 5dB improvement is achieved.
The Reuss has one USB, one RCA, one Toslink and one AES input. The USB input is based on Amanero technology and ensures a low-jitter music signal thanks to two precise oscillators, which is then galvanically isolated by capacitive isolator components. The signals arriving at the other inputs are also galvanically isolated and de-jittered by means of transformers and capacitors. This guarantees that no external interference can affect the sensitive signal.
The task of digital-to-analog conversion is performed by two 1794A converter modules from Burr Brown. For a 5 dB improvement in dynamic range, each channel has its own device. The analog current signal is elaborately converted into a voltage signal in a discrete setup, which is buffered in Class A technology and routed to the output. The Reuss is fully balanced, i.e. a total of four independent channels are implemented from the two converter modules to the output.
Power supply: Each functional unit has its own power supply, and in total there are twelve of them. Two output channels each are supplied by a separate linear supply with an oversized transformer.
The sound influence of components and circuit variants as well as various layouts were thoroughly tested in countless sessions by experienced listeners. This applies in particular to capacitors, voltage regulators, converter components, transistors, resistors, signal processing, I/V converters and output stages.
The manufacture of the housing, the front panel and the control knobs and the printing, component placement, assembly, commissioning and inspection are carried out exclusively in Switzerland.
