Welcome to the world of serious non-oversampling D/A converters. Audial is specialist in this area, and Audial DACs design is always the outcome of serious and devotional research and development.

At this moment Audial offers three D/A converters. Two reference Model S units based on TDA1541A chip, one of them having a classic S/PDIF input, and another one inteded for use with PC via USB interafce.

The third is the D-09, which applies somewhat simpler approach in a D/A and output stage design, and expands on flexibility.

The table below points out the main features of Audial DACs.
