The DAC9 digital-to-analog converter decodes most current formats with state-of-the-art vacuum tube technology.
Five digital connections - USB, RCA, BNC, AES/EBU, and Toslink - provide connectivity to all of your digital sources.
OVERVIEW
The DAC9 digital-to-analog converter decodes most current formats with state-of-the-art vacuum tube technology. Five digital connections - USB, RCA, BNC, AES/EBU, and Toslink - provide connectivity to all of your digital sources. Quad DAC architecture provides a balanced digital signal, wide dynamic range, and decoding resolutions from red book CD up to 384 kHz and native DSD sampling rates.
A pair of 6H30 vacuum tubes are the heart of the analog circuit. Both balanced and single-ended connectors are provided for output connectivity. Native-rate upsampling and selectable digital filters allow customization of the digital signal.
FOUNDATION SERIES
Audio Research is pleased to introduce the Foundation Series. From the same engineering and design team responsible for the award-winning Reference Series, the Foundation family of vacuum tube components has been created to provide incredible musical experiences. Spatial definition, dynamics and detail abound while providing the most natural musical experience.
Since 1970, High Definition has been more than ARC’s trademark; it has been their guiding principle for all products. The Foundation Series continues this passion and philosophy, offering the listener stunning playback, great value, and unparalleled long-term support.
All products at Audio Research follow the exact same path from concept to production, regardless of the series or model. The Foundation Series shares the same lineage, build quality, and many design characteristics found in the more costly Reference Series. The result is a consistency in the Audio Research sound, and the ability to create a range of components which offer exceptional performance and value.
