Upsampling Digital-to-Analogue Converter


The Ar38SE was designed to match the Ti48 Transport. Using the custom I2S digital connection, the pair functions as a high-end CD player but with the added benefits that the separation of the transport and DAC sections convey.

As a standalone product however, the Ar38SE is itself a high quality audiophile DAC with upsampling capabilities to 24 bits/96khz.

In designing the Ar38SE, our aim was to create the most natural sounding digital audio component possible with today's technology. Therefore, the Ar38SE only uses a passive second-order filter and discrete Class A analogue stages. Upsampling CD data results in higher bandwidth of the converted data. This allows the use of a gentle second order filter, following the digital section, to remove most of the ultra-sonic hash (a normal result of the digital-to-analogue conversion) from the analogue output. The use of such a low order filter reduces phase changes and filter-related ringing of the signal.

The entire analogue stage, including the output section, is implemented with a single-ended, Class A, discrete circuit operated without feedback loops. The whole design is DC-coupled, a feature very seldom found in single-ended designs.

The SE model differs from the original Ar38 by the addition of a separate power supply for the digital section. This vastly improves the resolution and clarity of the DAC.

When connected to the Ti48 transport, using our custom I2S link, the data can be upsampled in the Ti48 to 24 bits/192khz and then transmitted directly to the Ar38SE's DAC chips, thereby ensuring that interface jitter is negligible.

Other digital sources connected to the Ar38SE using the S/PDIF (coaxial) link will be upsampled to 24 bits/96khz.
