Audioaéro’s La Fontaine valve-output-stage digital front-end is offered in black or silver as a "music center" consisting of a full CD/SACD player with a DAC section that accepts five digital inputs (with USB for up to 192kHz processing, €17,000), or it can be purchased as a standalone DAC (€12,000). With variable output and two analog inputs, La Fontaine can double as a preamp.
