    NAD C 658 Preamplifier & DAC With BluOS Streaming

    The NAD C 658 is a Preamplifier and Digital Audio Converter with BluOs streaming capabilities. BluOs is a music management software that allows users to stream and access music on any device within your home network, allowing users to project audio using a smartphone, tablet, or controller. This powerful preamp helps audiophiles upgrade their sound system for the 21st Century by fulfilling the roles of a network streaming device, digital audio converter, and a standard preamp, all in one. This creates a highly controlled and balanced sound, in one neat, cost-effective package.

    High Resolution in Every Detail
    Most NAD components have been High Res for 45 years with very wide bandwidth, low distortion, and ultra-low noise. We just never had High Res source material to play. With High Res digital recording and streaming, combined with advanced technology like MQA, record companies are opening their vaults and releasing Studio Master Quality recordings. MQA decoding is available through BluOS Streaming content. The C 658 is pure High Res from input to output and features the ESS Sabre 32bit DAC , one of the best performing DACs on the market today with its 118dB Dynamic Range and incredibly low jitter spec. All preamp functions are executed in the digital domain including the same wide range non-truncating digital volume control used in our Masters Series components. This offers an incredibly short analog signal path that, rather uniquely, is identical for all volume settings. Sophisticated active power supplies provide super clean voltages to all circuits to keep noise and distortion at the edge of measurability.
