For decades, audiophiles have organized their systems with a source component, such as a CD player, along with a preamplifier and a power amplifier driving a pair of speakers. However, times have changed and today many music lovers have replaced their physical media with digital music files. It is for this purpose that the C 510 DirectDigital™ Preamp/DAC was created. Harnessing the power of DirectDigital, the C 510 accentuates all music tracks, delivering a gripping and engaging musical experience when combined with your favourite power amplifier.
